| 1 | 长江流域全新世环境考古研究进展显示文摘长江流域是我国重要的经济区和人类文明孕育、诞生和发展区,也是水旱等自然灾害频繁发生的地区,在该区开展全新世环境考古研究,对弄清全新世10.0~3.0 ka BP无文字记载期的环境演变和人地关系互动影响有着重要的科学意义。近年来,长江流域全新世环境考古主要以古洪水和海面变化事件地层学为依据和线索,从遗址时空分布学研究、典型遗址考古地层学研究,以及区域内自然沉积地层记录的环境演变背景特征研究这三个方面入手,在长江流域的上、中、下游地区均获得了有重要意义的进展,表明长江流域全新世环境考古正在向更深更广的领域发展。同时,国际环境考古研究也在不断深入发展,新出版的PAGES Magazine杂志就特别关注了分辨率高达一年至数月的过去沉积记录;遥感、GIS等技术和DNA等分子生物学技术正不断在环境考古领域得到应用。 | 朱诚 吴立 李兰 郑朝贵 李中轩 马春梅 谭艳 赵泉鸿 王坤华 林留根 江章华 丁金龙 孟华平 | 2014 | 地理学报2014,69,9: | 20 |
| 2 | High-resolution geochemistry records of climate changes since late-glacial from Dajiuhu peat in Shennongjia Mountains,Central China显示文摘A peat core with depths of 297 cm was obtained from the Dajiuhu Basin(31°29′27″N,109°59′45″E,1760 m)in Hubei Province,Central China.10 AMS ages provide a time control and reveal that this core spans the past about 16.0 kaBP(calibrated age)(1 4C age:13.3 kaBP).Multi-proxy indexes analysis of geochemistry shows the following character of climate and environmental changes since about 16 kaBP:(1) The climate during the late-glacial period was cold and wet as a whole,but fluctuated continually.11.4- 12.6 cal.kaBP,12.6-15.2 cal.kaBP and 15.2-16 kaBP were corresponding respectively to the Younger Drays,Bφlling-Allerφd Warm Period and the Oldest Drays.(2)Inheriting the some climate characteristics of the late-glacial,the climate during the early-Holocene was wet and temperature increased gradually,during which an obvious dry event around 10.6 cal.kaB appeared.(3)The climate during the mid-Holocene was genarally warm and wet.During 9.2-7.5 kaBP,temperature increased gradually, precipitation was less comparatively and the 8.2 kaBP cold event which might be representative in the globe was reflected markedly.Then,multi-proxy records were relatively stable during 6.7-4.2 kaBP, which shows the best water and thermal condition in the Holocene Optimum.(4)Around 4.2 kaBP,the climate and environment transform from warm and wet to cool and dry,which may result in the collapse of the Neolithic Culture and midwifery the civilization of Xia Dynasty in this region.After 0.9 kaBP,the climate turned cool and wet.Climate and environmental changes archived in Dajiuhu peat respond to the global changes since the late-glacial period and can be contrasted to the changes recorded in other high-resolution archives from the East Asia Monsoon region,which take on the variety model that the monsoon strengthened abruptly after the late-glacial,was strong during the early Holocene,subse- quently declined and became weak after the middle Holocene with dry climate.According to our analysis,the driving mechanism should be the response of solar radiation changes in the East Asia Monsoon region at middle latitudes. | MA ChunMei ZHU Cheng ZHENG ChaoGui WU ChunLin GUAN Yong ZHAO ZhiPing HUANG LinYan HUANG Run | 2008 | Chinese Science Bulletin2008,53,S1: | 19 |
| 3 | Characteristics of paleoflood deposits archived in unit T0403 of Yuxi Site in the Three Gorges reservoir areas,China显示文摘Based on the detailed analyses,multi-proxies such as AMS 14 C dating,grain size,component and morphology of heavy minerals,micromorphology of zircon,magnetic susceptibility,Rb/Sr and Hg content are used to research the paleoflood sediments archived in the Yuxi Site.The research indicates that, since 7.6 kaBP,at least 16 times of paleoflood with water level above Wusong Elevation 147.024 m(a.s.l.) left deposits in the Neolithic layers of unit T0403 from the Yuxi Site.The results are induced from the following aspects:(1)The plaeoflood sediments take on great similarities with modern flood sediments in the Yuxi Site and Zhongba Site in probability cumulative curves which mainly show a pattern of 3 segments in fluvial pattern.(2)There is some resemblance between the heavy mineral components and the zircon shape characteristics of paleoflood deposits and those of modern flood deposits.(3) Magnetic susceptibility values(40.44―70.10SI)are lower than those of sediments from cultural layers (59.59―188.68SI).(4)Hg values(290.71―742.51 ng/g)are lower than those of sediments from cultural layers(344.16―10518.17 ng/g).(5)Rb/Sr values are higher than those of sediments from cultural layers, while those of the 4th,5th,6th,7th,8th cultural layers are high,which shows that they are inundated by paleoflood.The reason for many flood deposits existing is related to the site situated on the first terrace where the Yuxi River joins with the Yangtze River.As there are some similarities between the plaeoflood sediments and those of the Zhongba Site,it is feasible to confirm the existence of paleoflood sediments based on the above points. | ZHU Cheng MA ChunMei XU WeiFeng BAI JiuJiang ZHENG ChaoGui ZHU GuangYao WANG HuiLin CHEN Ye LU XueFeng | 2008 | Chinese Science Bulletin2008,53,S1: | 16 |

| 5 | 江汉平原钟桥遗址地层揭示的史前洪水事件显示文摘通过野外考古调查研究,利用对钟桥遗址疑似古洪水层和研究区现代洪水沉积物的锆石微形态、粒度、磁化率、Rb/Sr等地球化学指标的比较、AMS14C技术和考古器物断代,发现钟桥遗址在4800~4597 cal.a BP、4479~4367 cal.a BP和4168~3850 cal.a BP分别经历了三次古洪水事件并相应堆积了古洪水沉积层;结合江汉平原及其周边地区众多遗址的古洪水沉积层时代对比证据,揭示了屈家岭文化中晚期(4900~4600 cal.a BP)和石家河文化末期至夏代(4100~3800 cal.a BP)两次大洪水事件在江汉平原地区非常普遍。对史前洪水发生环境背景的进一步分析,反映江汉平原在5000~4500 a BP及4000 a BP前后的时段气候表现得不稳定,古洪水事件与气候环境变化驱动的江汉平原湖群扩张存在一定的联系,并影响区域新石器文化兴衰过程。同时,其它证据也表明该区社会发展过程和环境变化过程特别是古水文过程的矛盾在石家河文化末期已特别突出,发现具有全球意义的4000 a BP前后气候异常引起的大洪水事件是江汉平原地区石家河文化消亡的重要环境因素;而石家河文化末期该区内部或同中原以及其它地区间的冲突,都加速了石家河文化的崩溃。这些研究成果,提供了可靠的大禹时代史前洪水证据来说明其对新石器文化兴衰的社会影响,对于揭示4000 a BP气候事件中区域气候水文变化的响应规律,亦具有重要的科学意义。 | 吴立 朱诚 李枫 马春梅 李兰 孟华平 刘辉 王晓翠 谭艳 宋友桂 | 2015 | 地理学报2015,70,7: | 13 |
| 6 | 长江三峡库区中坝遗址地层洪水沉积粒度特征及其沉积环境显示文摘通过对三峡库区中坝遗址1981年洪水沉积和疑似古洪水沉积的粒度对比分析,发现它们的平均粒径、分选系数、偏度、峰度和众值粒径都在同一值域范围内;频率分布曲线相似,呈单峰态;概率累积曲线都呈明显的三段式。从而推断出中坝遗址的文化间隙层为古洪水沉积。在考古断代和AMS14C测年基础上,对洪水沉积环境研究发现,中坝遗址洪水沉积大多发生在我国的暖期,但周朝和宋代的洪水沉积发生在我国冷期,这与我国气候小循环和当地独特的地貌特征有关。清代以后,沉积物平均粒径明显变大,表明当地植被已经退化;沉积物平均粒径和峰度变化幅度大,说明人类活动使当地生态系统变得脆弱,气候多变。 | 田晓四 朱诚 尹茜 孙智彬 | 2007 | 沉积学报2007,25,2: | 12 |

| 8 | Reconstruction of flood events over the last 150 years in the lower reaches of the Changjiang River显示文摘The reconstruction of paleofloods in the Holocene has become one research highlight for the present global change study.The core sediments from one newly-emerged bar in the lower Changjiang River(Yangtze River)mainstream were collected for grain size and organic elemental measurements,with aim to reconstruct the flood events over the past 150 years.Major grain size parameters such as mean grain size,probability cumulative curve and C-M diagram of the core sediments clearly indicate the flood event deposition.Furthermore,the TOC/TN ratios in the sediments can indicate flood events considering that during the flash floods,strong surface erosion in the upper and lower reaches of the Changjiang River can transport a large amount of undecomposed plant debris and organic components with relatively low C/N ratios into the lower mainstream.Based on 210Pb dating and sedimentary geochemical results,the research profile recorded several large floods happened from 1850 to 1954,which agrees well with the historical documents and hydrological observations.Interesting to note that the flood events since the 1960s cannot be distinctly recognized on the basis of sediment grain size and organic elemental compositions of the profile,which mainly reflects the intensive human activities over the last fifty years,especially condense dam construction,have significantly changed the characters of suspended sediment into the lower mainstream. | ZHAN Wang YANG ShouYe LIU XiaoLi LI JianWei CHOI ManSik | 2010 | Chinese Science Bulletin2010,55,21: | 9 |
| 9 | Spatial pattern and temporal trend of prehistoric human sites and its driving factors in Henan Province, Central China显示文摘Yangshao 文化(约 6.95.5 ka BP ) 和 Longshan 文化(约 4.64.0 ka BP ) 在河南省过时的时期起了重要作用。由于 Yangshao 文化地点的空间分发,他们在 Longshan 时期与那些比较有一个面向河的趋势。除了地面因素,在两个时期的地点的分发服从于 paleo 环境的变化。Yangshao 文化在 Holocene 最佳时期发源,并且 Longshan 文化在过时的结束以前在气候的变化开始了。但是后者比前者做的拥有了更多的地点和更宽的范围。文化在富有的降雨和温暖的时期快发展了,并且分别地在 5.4 ka BP 和 4.0 ka BP 为突然的冷却事件凋谢了。因此,河南省过时的文化的可持续性不好是期望。虽然,古老的耕作在人的地点,和需要的分发扮演了不能替代的部分因为耕作空间提示了人的地点向河南省的东方平原从西方的多山的区域膨胀。而且,附近的文化流进河南省并且复杂文化模式。而且,在 Erlitou 时期的地点的特征建议一些社会因素在河南省在过时的年龄的结束扰乱了空间模式。 | LI Zhongxuan ZHU Cheng WU Guoxi ZHENG Chaogui ZHANG Pengju | 2015 | Journal of Geographical Sciences2015,25,9: | 7 |
| 10 | 黄河兰州段高河漫滩洪水沉积及其气候意义显示文摘根据兰州黄河高河漫滩沉积剖面中60个样品的粒度分析,研究了兰州黄河140aBP来河漫滩沉积指示的洪水变化。结果表明,黄河兰州段高河漫滩沉积剖面分层明显,对洪水的发生和短期降水量变化反映清楚,分辨率高,能够作为较好的指示洪水和降水量变化的指标。黄河河漫滩沉积物的粒度成分反映了沉积时期洪水搬运动力的强弱变化,粒度成分较粗,指示沉积时期洪水搬运动力较强;粒度成分较细,指示沉积时期洪水搬运动力较弱。研究剖面分为10个沉积阶段,指示了10次大小不同的洪水和10个降水较多的年份。10个洪水阶段之间为没有洪水发生或洪水规模很小的阶段,指示降水正常或贫乏的年份。剖面第4层为1904年的洪水沉积,代表的最大洪水流量为8500m3/s,第5、6、7、8、9、10阶段洪水规模都要小于1946年,最大洪水流量小于5900m3/s,即140~100aBP间最大洪水流量小于5900m3/s。剖面粒度特征随着深度具有明显的粗细变化规律。根据各层粒度组成特征及确定漫滩洪水深度的依据,可以得出剖面10个阶段河漫滩洪水深度和规模,由大到小的变化顺序依次为第4阶段>1阶段>2阶段>8阶段>3阶段>9阶段>7阶段>5阶段>6阶段>10阶段。LS剖面10个洪水阶段都是由兰州及以上黄河流域或洮河、大通河、大夏河等支流当年降水量明显增加造成的。 | 王长燕 赵景波 郁耀闯 | 2008 | 海洋地质与第四纪地质2008,28,4: | 6 |
| 11 | 长江三峡库区全新世环境考古研究进展显示文摘充分利用长江三峡工程文物抢救性发掘的宝贵机会,通过对重庆市忠县中坝遗址、丰都县玉溪遗址等典型遗址和神农架大九湖泥炭地层环境考古研究,摸索出了一套利用年代学、沉积学、重矿物组分鉴定、锆石形态统计、地球化学和环境磁学方法辨别考古遗址地层中古洪水沉积的方法;建立了该区地表孢粉-气候的转换函数,并将其用于对神农架大九湖泥炭地层的研究,弄清了该区全新世以来环境演变的背景,并将自然沉积地层环境演变记录与典型考古遗址地层古洪水事件作了对比分析。遗址时空分布研究表明:长江三峡库区旧石器时代至宋代677处遗址时空分布总趋势是从西往东、从高往低逐渐增加的,遗址多沿江河分布,且在河流交汇处呈聚集状态,这与人类多选择河流1~2级阶地为生、河流交汇处鱼类资源丰富有关。研究表明:中坝遗址能延续5000a的原因一方面与其盐业遗址的属性有关,另一方面与其长期具有良好生态环境有关。从该遗址T0202探方出土近20万件动物骨骼的分类统计证明了这一点。7.6kaBP以来,水位在吴淞高程147.024m以上的古洪水至少在玉溪遗址T0403探方中留下了16次沉积记录。神农架大九湖297cm厚的泥炭及其148个孢粉样品和10个AMS14C测年数据表明,该泥炭地层为本项目提供了理想的全新世自然环境演变背景,尤其8.2kaBP前后的降温事件很明显,6.7~4.2kaBP为中全新世最适宜期,4.2kaBP前后由暖湿转为凉干,3.5~0.9kaBP季风降水整体较弱,0.9kaBP前后转为较凉湿。根据对中坝和玉溪两处遗址地层的研究,在8.2~6.7kaBP期间出现有10个古洪水层;在6.7~4.2kaBP全新世最适宜期遗址地层中出现有8个古洪水层;在3.5~0.9kaBP降水减少的时期,中坝遗址中仅出现2个洪水层(即西周时期的37-1和战国早期的第21层);在0.9kaBP以来降水较多的时期,中坝遗址中存在3个洪水层(即宋代中期的11C-1层、清代的5-1层和1981年的2B-2层)。这表明,8.2~6.7kaBP的洪水在三峡地区次数是最多的,6.7~4.2kaBP的洪水数量次之。长江三峡库区的这一古洪水发生规律或许可以解释长江中游的江汉平原在7.8~5.1kaBP期间遗址数量偏少的原因。 | 朱诚 马春梅 李兰 孙智彬 郑朝贵 白九江 朱光耀 黄润 | 2010 | 地学前缘2010,17,3: | 6 |
| 12 | Reconstructing the extraordinary palaeoflood events during 3200-2800 a BP in the upper reaches of Hanjiang River Valley, China显示文摘Palaeoflood hydrology study is a leading subject in global change study. Through field investigation in the upper reaches of Hanjiang River, palaeoflood slackwater deposits(SWD) were found in the bedrock gorges of the Yunxi reach. The results of field observation, laboratory analysis including particle-size distribution and magnetic susceptibility, and comparison with modern flood deposits, the SWD were identified as the most typical Holocene palaeoflood deposits of the Hanjiang River. By using stratigraphic correlation and OSL dating method, the palaeoflood event was dated to be 3200–2800 a BP at the turn from the middle to late Holocene. According to the palaeoflood peak stage and hydraulic parameters, the peak discharges of the palaeoflood were reconstructed as 48,830–51,710 m3/s by using the slope-area method. At same time, the flood peak discharges of 1983, 2005 and 2010 severe floods were reconstructed with the same method and hydraulic parameters in the same cross section. The error between the reconstructed and gauged discharges was 1.99%–4.21%. This showed that the reconstructed palaeoflood peak discharges were reliable. The flood peak discharge-frequency relationship at 10,000-year time scale was established by a combination of the gauged flood, historical flood and palaeoflood hydrological data. These results are very important for hydraulic engineering and flood mitigation on the Hanjiang River. | ZHA Xiaochun HUANG Chunchang PANG Jiangli ZHOU Yali | 2014 | Journal of Geographical Sciences2014,24,3: | 5 |
| 13 | 江苏宜兴骆驼墩遗址地层全新世沉积环境研究显示文摘主要通过对骆驼墩遗址地层样品的粒度和重砂矿物的鉴定、样品中锆石形态的对比研究,铷锶值的测定与分析,了解该区域全新世以来的沉积环境及其气候变化,探索气候变化与人类文明和文化发展的关系。对骆驼墩遗址文化层下的自然淤积层的粒度分析和锆石形态研究发现该区域在人类出现之前可能经历过浅水泻湖环境;结合重矿物及铷锶研究发现,该区域在全新世早期降水量较大,气候较为湿热,之后气候逐渐变得温暖湿润,为人类文明的出现和文化的发展提供了一个优越的气候条件;通过对地层中文化层样品的重矿物鉴定及百分含量分析、ZTR稳定系数及Rb/Sr分析发现,全新世的气候是不断变化的。尤其在马家浜文化时期、良渚文化时期和广富林文化时期气候经历过温湿与干凉的交替变化过程。同时良渚文化时期的中晚期稳定系数出现了该地层的最高值,说明当时气候较为湿热,降水量偏多,这与良渚文化的消失与洪水有关的结论相一致。 | 李兰 朱诚 林留根 张广胜 欧阳杰 周慎明 | 2010 | 第四纪研究2010,30,2: | 5 |
| 14 | Archaeological discovery and research on the remains of the paleoflood of the Yuxi site显示文摘The research of the paleoflood remains from archaeological sites is one of the most important jobs in the environmental archaeology.Based on the traditional archaeological methods and the archaeological finds from the Yuxi site,Fengdu County of Chongqing,the paper analyzes the difference between the cultural layers and the possible paleoflood layers from various angles,such as contents,shapes of gravels,pottery,etc.,identifies the possible paleoflood deposit layers,i.e.the paleoflood remains of the Yangtze River,and discusses the periodicity of the floods. | BAI JiuJiang ZOU HouXi ZHU Cheng | 2008 | Chinese Science Bulletin2008,53,S1: | 5 |
| 15 | Animal diversities and characteristics of environmental change revealed by skeletons unearthed at Zhongba Site of Chongqing City,China显示文摘Nearly 200000 animal skeletons are unearthed in the Unit T0202 from Zhongba Site of Zhongxian County.According to the analysis of 129165 specimens,these skeletons may be classified into 5 kinds, namely,Mammalia,Osteichthys,Aves,Amphibian and Reptilia,which belong to 13 orders,28 families and 42 genera.In this paper,based on archeological dating and AMS 14 C data,through statistically analyzing the unearthed skeletons and studying the change of the smallest individual numbers,these research results detected the following:1)In almost all the time of 2370―200 BC,in Zhongba region, some animals distributed widely,such as Muntiacus sp,Elaphodus cephalophus and Muntiacus sp. inhabiting in glade and grassland,Scrofa sp.and Canis familiaris raised by the ancient people,rodentia rabbit and Rattus rattus,which suggested that a fairly good ecological environment of forest and grassland was preserved at that period and the predecessors began to raise domestic animals from 1750 to 1000 BC,which has lasted until today.2)Rhinoceros only lived during 2000―1750 BC,1000― 700 BC and 700―500 BC,which indicates that the ecological environment of grassland and wetland might be better in these phases.3)Macaca sp.and Ursus arctos appeared only after 1750―1000 BC, which may show that the forest condition is better for animals to live during 1750―200 BC.4)The smallest individual numbers of Bublus sp.,bos sp.and otters emerged during about 2370―1750 BC, which perhaps infers that water area during the early period was wider than that of the late period.5) Since skeletons of rhinoceros are discovered in strata of Zhongba Site during 2000―1750 BC and 1000―500 BC,according to the climate and ecology environment which rhinoceros live in now,the average annual temperature and precipitation during 2000―1750 BC and 1000―500 BC are supposed to be probably higher than that of today.Although Zhu Kezhen considered that the first low temperature period in the past 5000 years of China was between 1100 BC and 850 BC,massive pollen of Morus, Ulmus,Fagus,Quercus,Castanea,etc.were found in Dajiuhu peat at that time,which should indicate that the climate was still moderate for living things to live at least in Dajiuhu basin and Zhongba Site.6) Because skeletons of Gervus albirostris were unearthed during 310―200 BC at Zhongba Site,based onthe climate and the ecological environment those animals live in now,the average annual temperature and the average annual precipitation in Zhongba area between 310 BC and 200 BC should be lower than those of today,which is confirmed by the TOC research of Zhongba Site strata. | ZHU Cheng MA ChunMei OUYANG Jie LI ZhongXuan YIN Qian SUN ZhiBin HUANG YunPing R.K.FLAD LI Lan LI YuMei | 2008 | Chinese Science Bulletin2008,53,S1: | 4 |
| 16 | Reconstructing past subsistence patterns on Zhongba Site using stable carbon and oxygen isotopes of fossil tooth enamel显示文摘The oxygen and carbon isotopic ratios in human and animal tooth enamel were measured to reconstruct the subsistence patterns on Zhongba Site between 2400 and 4200 aBP.The results indicate that human consumed chiefly C4 resources,such as millet,and the C3 plants,such as rice and wheat,constituted only a small fraction of the human diets,normally no more than 15%.There are significant differences in food sources between human and pig,and the percentages of C3 plants in pig diets were higher than those in human diets.But theδ13C values of pig partially overlap those of human,demonstrating some similarities in their food sources.The differences in water sources between human and pig are significant.There are significant differences in food and water sources between cattle and deer. This indicates that the two kinds of mammals subsisted in different niches.But theirδ13C values also partially overlap each other,suggesting some similarities in their food sources.There are both signifi- cant differences in meanδ13C andδ18O values between the omnivores,human and pig and the herbi- vores,cattle and deer,implying significant differences in food and water sources between the two categories.During the period the dietary habits of human had not changed,but the pig breeding strategies had changed,from breeding in house to breeding in confinement,and the proportion of C3 plants in pig food increased with time.The scope of human migration had been considerably large by the Warring States because of the development of productive forces. | XiaoSi Tian Cheng Zhu XinWang Xu ChunMei Ma ZhiBin Sun Qian Yin Qing Zhu Wei Shi | 2008 | Chinese Science Bulletin2008,53,S1: | 4 |
| 17 | Environmental archaeology of the Dachang region in the Daning Valley,the Three Gorges reservoir region of the Yangtze River,China显示文摘Environmental archaeology of archaeological sites on both sides of the Dachang section in the Daning River,the Three Gorges of the Yangtze River,shows that riverbed evolution has a great influence on the distribution of archaeological sites during the prehistorical and historical period,and it restricts human activity and the development of ancient culture.Field investigation,dating data,paleocurrent analysis of 100 gravels on the riverbed and archaeological excavation reveal that the riverbed of the Dachang section developed in the Shuangyantang region during the early stage,after about 30 kaBP it shifted westward gradually and reached the present place.Along with the westward shift,the focus of ancient culture changed for several times.In the Western Zhou Dynasty's period,the east riverbank of the Daning River was the main residential area.During the Han Dynasty,along with the westward shift,the living space of ancient people was no longer confined to the east riverbank and the focus of culture moved westward.Then the Zhangjiawan site became the main dwelling district.In the late Han Dynasty, the villages were flooded and the ancients had to immigrate to a high place.Tombs of the Han and the Jin Dynasties outcropped on the flood plain of the east bank because their surface sediments were eroded by several flood events and the westward shift of the riverbed. | ZHANG Yun 1 &ZHU Cheng 2 1 State Key Laboratory of Vegetation and Environmental Change,Institute of Botany,Chinese Academy of Sciences,Beijing 100093, China 2 School of Geographic and Oceanographic Sciences,Nanjing University,Nanjing 210093,China | 2008 | Chinese Science Bulletin2008,53,S1: | 4 |

| 20 | 重庆市玉溪遗址古洪积地层的粒度特征显示文摘通过玉溪遗址T0403探方11个古洪积层粒度参数分析,发现该遗址古洪积层的特征是:①遗址古洪积层粒度频率曲线为单峰正偏,分选差,概率累积曲线为典型三段式,且推移质组分〉40%;②洪积层角闪石、磷灰石等不稳定矿物含量高于现代洪水层,表明古洪积层主要为近源沉积。联系到古洪积层形成期(6.3~7.5 ka B.P.)属于全新世大暖期的高温波动期,干湿波动是造成玉溪地区洪水频发的主要原因,同时根据遗址文化地层出土的器物判断,古洪积层沉积粒度特征变化与新石器人类的农业生产活动有关。 | 李中轩 闫慧 朱诚 吴国玺 | 2012 | 土壤通报2012,43,3: | 4 |
