| 1 | Identifying paleoflood deposits archived in Zhongba Site,the Three Gorges reservoir region of the YangtzeRiver,China显示文摘Based on the principle that the present is the key to the past , detailed analyses, such as AMS 14C dating, grain size, component and morphology of heavy minerals, micro-morphology of zircon, Rb/Sr, magnetic susceptibility and total organic carbon (TOC), were conducted to identify paleoflood sediments archived in Zhongba Site. The results indicate that the plaeoflood sediments bear great similarities with modern flood sediments in the following aspects: (1) probability cumulative curves mainly show a pattern of 3―4 segments; (2) grain-size distribution of suspended matter ranges between 3 and 10Ф; (3) the sediments are well-sorted, most of which are suspended matter (>50%); (4) the same species, quantity and morphology of heavy minerals; (5) scanning electronic microscope images show that shapes of zircon are mainly oval and nearly spheral, rounded due to long-distance transport; (6) higher Rb/Sr values (0.55―0.66)than those of sediments from cultural layers (0.03―0.26); (7) magnetic susceptibility values (133.73―433.05 10-6m3/kg) are lower than those of sediments from cultural layers (959.25―2442.44 10?6 m3/kg); (8) TOC (0.14%―0.33%) are lower than those of sediments from cultural lay-ers (1.13%―2.95%). Our results demonstrate that, except for the 1981 flood, there are at least six paleoflood events that occurred during the Qing Dynasty, the middle of Song Dy-nasty, the early Warring States (400BC―350BC), the West Zhou Dynasty (920BC―900BC), the Xia Dynasty (2070BC―1600BC), and the late Neolithic Age (3000BC―2300BC), respectively . | ZHU Chen ZHENG Chaogui MA Chunmei SUN Zhibin ZHU Guangyao WANG Huilin GAO Huazhong WANG Pengling HUANG Run | 2005 | Chinese Science Bulletin2005，50，21： | 28 |
| 2 | Climate changes in East China since the Late-glacial inferred from high-resolution mountain peat humification records显示文摘High-resolution peat humification records were obtained from Dajiuhu of the Shennongjia Mountains and Qianmutian of the Tianmu Mountains to study climate changes in East China.The analyses of pollen,organic matters,TOC,and Rb/Sr indicate a high degree of peat humification and thus strong decomposition of organic matter when climate was dry.Conversely,when climate was humid,the degree of humification is low because peat was preserved in a waterlogged condition.Peat humification from Dajiuhu occurred not only during the Younger Dryas(about 11.4-12.6 cal ka BP),the Blling-Allerd Warm Period(12.6-15.2 cal ka BP),and the Oldest Dryas(about 15.2-16.0 cal ka BP),but also during the early Holocene(about 11.4-9.4 cal ka BP),the 8.2 cal ka BP cold event,and the Holocene Optimum(about 7.0-4.2 cal ka BP).Both peat humification records since nearly 5 ka BP are consistent,showing that mountain peatland has synchronous responses to the East Asia monsoon-induced precipitation.The LOI data confirm the above observation.The monsoon precipitation since nearly 5 ka BP recorded in these two peat profiles can be divided into three phases.During 4.9-3.5 ka BP,precipitation amount was high but fluctuated greatly.During 3.5-0.9 ka BP,precipitation amount was low.During 0.9-0 ka BP,degree of humification reduced gradually,indicating the increase of monsoon precipitation.Contrast to other high-resolution records from East China monsoon region shows that the monsoon precipitation records of the two peat profiles since nearly 16 ka BP are controlled by a common forcing mechanism of summer solar radicalization in the Northern Hemisphere. | MA ChunMei ZHU Cheng ZHENG ChaoGui YIN Qian ZHAO ZhiPing | 2009 | Science China Earth Sciences2009，52，1： | 22 |
| 3 | 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 |
| 4 | 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 | Relationship between the temporal-spatial distribution of archaeological sites and natural environment from the Paleolithic Age to the Tang and Song Dynasties in the Three Gorges Reservoir of Chongqing area显示文摘The temporal-spatial distribution features including time distribution,horizontal and vertical spatial distribution of archaeological sites from the Paleolithic Age to the Tang and Song Dynasties in the Three Gorges Reservoir of Chongqing area are analyzed based on GIS spatial analysis.The successive pollen record of deposited peat stratum since the Paleolithic Age in the Dajiuhu Basin of Shennongjia is used in combination with the research of the historical environmental evolution to reconstruct the Paleoenvironment in the Three Gorges Reservoir of Chongqing area.Through the comparison of the temporal-spatial distribution of the archaeological sites and the natural environment,the relation between the distribution of the archaeological sites and the natural environment evolution and disaster changes from the Neolithic Age to the Tang and Song Dynasties has been discussed.Study shows that 677 archaeological sites from the Paleolithic Age to the Tang and Song Dynasties in the Three Gorges Reservoir of Chongqing area increase gradually from west to east and from high land to low land.Most of the sites are distributed along the river and aggregated at the confluence.Obviously,the altitudes of archaeological sites in the Paleolithic Age and the Neolithic Age are much higher than those of historical sites.The analysis suggests:(1)the human beings of every times would like to choose the first or the second river terrace as living sites which are nearer to the water source and are easier to with- stand flood.The pre-historical sites of earlier ages are often located at the higher altitude place because of the tectonic uplift and downcutting of rivers since Holocene.(2)Due to the rugged terrain in Chongqing area,most of the sites are located along the river sides,for example,the wide river valley and terrace,which could provide wider living space caused by the lateral erosion and deposition of the river course.(3)The early residents mainly relied on fishing,hunting and agriculture,and the rugged terrain of the mountainous area restricted the development of farming.However,in the confluence region,the fertilized plain provided an ideal location for farming and fishing.(4)The temporal-spatial distribution of archeological sites in this area is significantly affected by the climate condition. | ChaoGui Zheng Cheng Zhu YiShun Zhong PengLian Yin JiuJiang Bai ZhiBin Sun | 2008 | Chinese Science Bulletin2008，53，S1： | 11 |
| 6 | Impact of Holocene climate change on the prehistoric cultures of Zhejiang region, East China显示文摘自从在浙江区域的 Holocene 比较地基于 GIS 空间分析被分析,时间空间的分发史前的文化展示。结果证明史前的文化在 4000 cal 前在这个区域逐渐地膨胀了。BP。著名扩大发生了两次,在 Majiabang-Hemudu 文化时期的,其它在 Liangzhu 文化时期。同时,史前的文化沿着河山谷从西方被传播到东方海岸。在 4000 cal 以后。BP 由 Maqiao 文化代表了每种史前的文化的分布式的区域收缩了。这显然由于散布趋势到东方海岸的结束,它被生产和经济转变的二个不同模式同时分别地在北方和南方浙江区域伴随。在史前的文化地点的分发变化被海平面的变化极大地影响的地方,史前的文化的分发与 Holocene 海平面的变化是密切相关的,特别在 Hangzhou 海湾的河岸上,在他们之间的最靠近的关系地。在 7000 cal 以后。BP,这个过程降低海平面并且 regression-epeirogenesis 为史前的居民提供了更宽的陆上的生活空格。基于史前的文化和在华东海的内部架上在塔恩穆山和泥泞区域的 Qianmutian 亚高山带的泥炭记录的环境进化信息的变化的比较分析,史前的文化的变化在浙江与环境变化被同步,这被显示区域。在 4000 cal 前。BP,史前的文化在的东方扩大浙江在 Holocene 最佳的背景下面发生了,并且在农业文明和海上的文明的联合影响下面是扩大和延期。然而,在 4000 cal 以后。BP,在浙江的史前的文化的地理收缩发生在干燥寒冷的气候趋势的背地面和沿海的海洋的环境的恶化下面。它从史前的文化的发展,扩大和收缩断然被相关到环境变化的上述事实被证实。气候的环境的变化只是为生产模式和经济形式的这些变化和转变的内在的原因。因此,气候的环境是在浙江区域的史前的文化变化的主导的因素,它对文化的分发,传播,扩大和变化施加了大影响。 | WU Li ZHU Cheng ZHENG Chaogui MA Chunmei WANG Xinhao LI Feng LI Bing LI Kaifeng | 2014 | Journal of Geographical Sciences2014，24，4： | 8 |

| 8 | 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 |
| 9 | Impact of Holocene environmental change on temporal-spatial distribution of Neolithic sites in Huaihe River Basin, Anhui Province显示文摘The Huaihe River basin of Anhui is not only a transitional zone of physical geography, but also a convergent area of many cultures in China. It is one of the sensitive ecotones to global changes and the birthplace of Chinese civilization. Using the field archaeological data and the sporo-pollens and the age data of the drilling cores, we analysed Neolithic cultural development and environmental evolution in the Huaihe River basin of Anhui. According to the combination of some research results in archaeology with environmental evolution research, this paper discusses the relationship between culture and environment in the Huaihe River basin of Anhui. The Neolithic cultural development was strongly impacted by the environmental change. The primitive culture (Shishanzi) was developed in the beginning of the Holocene Megathermal Period with distinct regional feature of the culture. From 6.5 kaBP to 5.5 kaBP, the climate changed warmer and wetter. The frequent occurrence of flood and waterlog due to such a climate regime and high sea level caused the earth’s surface environment deteriorated in the Huaihe River basin of Anhui and the interruption of the Neolithic cultural development, hence a lack of archaeological sites. From 5.5 kaBP to 4.0 kaBP, the climate changed from wet to dry, the natural environment was propitious to human survival. Dawenkou Culture and Longshan Culture flourished in this period. The Neolithic cultural development, the number of the sites and their distribution characteristics of the sites in the study area differed apparently from those in Central China and Shandong Province. | HUANG Run ZHU Cheng GUAN Yong ZHENG Chaogui | 2006 | Journal of Geographical Sciences2006，16，2： | 5 |

| 12 | Environmental archaeology on Longshan Culture (4500-4000 aBP) at Yuhuicun Site in Bengbu, Anhui Province显示文摘Based on the samples collected from the west wall of the ABYT2004 at Yuhuicun Site in Bengbu,Anhui Province,the multi-environmental substitute indexes such as the grain-size,Rb/Sr,zircon crystal morphology and magnetic susceptibility were analyzed.The age of archaeological strata was determined by AMS14C dating.According to the results,combined with the information of the ancient human activities and the cultural heritage data obtained from the Longshan cultural archaeological strata,it can be concluded that(1) Before 4500 aBP,the climate was humid and water level was high in the Huaihe River and its tributaries,the drainage basin and its surrounding areas were even flooded,so the site area was submerged and there were no human activities around the site.(2) About 4500 aBP,the climate began to become drier and water level of the Huaihe River and its tributaries began to decline,thus floodplain gradually appeared,Yuhuicun Site and Longshan Culture began to appear.(3) Around 4100 aBP,the climate was humid and rainfall was abundant,which resulted in frequent flood disasters in the whole Huaihe River Basin.(4) After 4100 aBP,the climate gradually transited to be cold and dry,agricultural production was constrained to reduce the food source,Yuhuicun Site was almost abandoned.(5) The environmental information in sedimentary strata and historical records based on ancient books agree with each other.In addition,Yuhuicun Site was related to Dayu Zhishui(Yu the Great in taming the floods) in ancient books. | ZHANG Guangsheng ZHU Cheng WANG Jihuai ZHU Guangyao MA Chunmei ZHENG Chaogui ZHAO Lanhui LI Zhongxuan LI Lan JIN Aichun | 2010 | Journal of Geographical Sciences2010，20，3： | 3 |
| 13 | Understanding Citizens’ emotion States under the Urban Livability Environment through Social Media Data: a Case Study of Wuhan显示文摘It is recognized that a city with a livable environment can bring happiness to residents.In this study,we explored the social media users’emotional states in their current living spaces and found out the relationship between the social media users’emotions and urban livability.We adopt six urban livability indicators(including education,medical services,public facilities,leisure places,employment,and transportation)to construct city livable indices.Also,the Analytic Hierarchy Process(AHP)spatial statistic method is applied to identify and analyze the different habitable regions of Wuhan City.In terms of citizen’s emotion analysis,we use Long Short-Term Memory(LSTM)neural network to analyze the Weibo text and obtain the Weibo users’sentiment scores.The correlation analysis of residents’emotions and city livability results shows a positive correlation between the livable city areas(i.e.,the area with higher livable ranking indices)and Weibo users’sentiment scores(with a Pearson correlation coefficient of 0.881 and P-Value of 0.004).In other words,people who post Weibo in high livability areas of Wuhan express more positive emotional states.Still,emotion distribution varies in different regions,which is mainly caused by people’s distribution and the diversity of the city’s functional areas. | Lai CHEN Chaogui KANG Chao YANG | 2022 | Journal of Geodesy and Geoinformation Science2022，5，2： | 3 |
| 14 | A framework for mixed-use decomposition based on temporal activity signatures extracted from big geo-data显示文摘Mixed use has been extensively applied as an urban planning principle and hinders the study of single urban functions.To address this problem,it is worth decomposing the mixed use.Inspired by the concept of spectral unmixing in remote sensing applications,this paper proposes a framework for mixed-use decomposition based on big geo-data.Mixeduse decomposition in terms of human activities differs from traditional land use research,and it is more reasonable to infer the actual urban function of land.The framework consists of four steps,namely temporal activity signature extraction,urban function base curve extraction,mixeduse decomposition,and result validation.First,the temporal activity signatures(TASs)of each zone are extracted as the proxy of human activity patterns.Second,the diurnal TASs of routine activities are extracted as urban function base curves(i.e.endmembers).Third,a linear decomposition model is used to decompose the mixed use and obtain multiple results(urban function composition,dynamic activity proportions,and the mixing index).Finally,result validation strategies are concluded.This framework offers method extensibility and has few requirements for the input data.It is validated by means of a case study of Beijing,based on a social media check-in dataset. | Lun Wu Ximeng Cheng Chaogui Kang Di Zhu Zhou Huang Yu Liu | 2020 | International Journal of Digital Earth2020，13，6： | 2 |
