| 1 | Spatiotemporal variations of Chinese lakes and their driving mechanisms since the Last Glacial Maximum:A review and synthesis of lacustrine sediment archives显示文摘In this article,the author provides the first synthesis and classification of available environment-indicating proxies for lacustrine sediment.A review of spatio-temporal variations in lakes from the Tibetan Plateau,the dry areas of Northwestern China,the Yunnan-Guizhou Plateau and the plains of Eastern China since the LGM is then provided.The driving mechanism for variations in lake processes and characteristics is also discussed based on various temporal scales.The author then proposes that future investigations be conducted to:(1) strengthen the study of theoretics and interpretation of environment-indicating proxies,(2) enhance the study of high-resolution time series and spatial variability of lake environment evolution,(3) provide more attention on the influence of human activities on lake environments,and(4) boost construction of the Quaternary lake database of China. | SHEN Ji | 2013 | Chinese Science Bulletin2013，58，1： | 20 |
| 2 | 黑龙江省五大连池近百年环境变化研究显示文摘2009年6月用重力采样器在黑龙江省五大连池的三池和五池分别采集岩芯钻孔(wdlc-3孔和wdlc-5孔),运用核素^(210)Pb和^(137)Cs进行定年,同时分析了岩芯沉积物的理化指标,包括烧失量(LOI_(550℃))、总磷(TP)、总氮(TN)、粒度、金属元素和磁化率,研究近代五大连池湖泊环境演化过程以及人类活动的影响。结果表明:1920s~1950s,湖泊沉积物中值粒径较大,LOI_(550℃)和TN呈增长趋势,两孔Al和Fe含量呈增长趋势或处于高值阶段,可能与该期人类活动如开垦荒地有关;1950s~1980s,中值粒径较小或呈减少趋势,而TN,Al和Fe及重金属的含量呈增加趋势,人类活动如毁林、毁草开荒开始成为湖泊环境变化的主导因素;1980s~2000s阶段氮、磷增加更为迅速,重金属的含量也呈快速增长趋势,这可能与化肥、农药、含磷物品、含铅汽油的大量使用以及增强的工业活动有关;2000s以来,湖泊主要面临营养水平增加导致的富营养化问题。 | 桂智凡 薛滨 姚书春 魏文佳 | 2011 | 第四纪研究2011，31，3： | 8 |
| 3 | Effect of precession on the Asian summer monsoon evolution:A systematic review显示文摘Geological climatic records and model simulations on the Asian summer monsoon climate change induced by insolation forcing of the Earth's precession are systematically reviewed in this paper.The presentation of the questions on the mechanism of the Asian monsoon evolution at the precession band,currently existing debates and future research directions are discussed.Since the early 1980s,more and more observed evidence and simulated results,especially the absolute-dated stalagmite records and orbital-scale transient model runs in the last few years,have indicated that the quasi-20ka period in the Quaternary monsoon climate change is caused by precession.However,debates still exist on the dynamic mechanism how precession affects the Asian monsoon.The 'zero phase' hypothesis says that the Asian monsoon is merely controlled by summer insolation in the Northern Hemisphere(NH) while the 'latent heat' hypothesis emphasizes the dominant effect of latent heat transport from the Southern Hemisphere(SH) besides the role of the northern insolation.The two hypotheses have separately been supported by some evidence.Although we are cognizant of the importance of northern solar radiation and the remote effect of southern insolation,it has still a long way to go before comprehensively understanding the evolutionary mechanism of the Asian monsoon.In view of the problems existing in present researches of monsoon-dominated climate change at the precession scale,we propose that studies on the environmental significance of geological monsoon proxies,feedback processes in the long-term transient simulations and intercomparisons between observations and modeling results should be strengthened in the future. | LIU XiaoDong SHI ZhengGuo | 2009 | Chinese Science Bulletin2009，54，20： | 8 |
| 4 | 鹤庆深钻孢粉记录揭示的气候变化与西南季风演化显示文摘本文在鹤庆深钻孢粉分析的基础上,把各孢粉类型划分成不同的孢粉生态组,结合孢粉多样性指数,系统重建云南鹤庆地区2.78Ma以来的古气候演化所经历的8个大的阶段,与西南季风在滇西北地区8次大的变化相对应:即在2.729—2.608Ma和0.118Ma—11.83kaBP期间,气候整体湿润,冬、夏季降水的季节性较强,反映西南季风相对较强盛;1.447—0.342Ma期间,气候整体逐渐变湿,冷暖、干湿变化幅度逐渐变大,气候组合特征逐渐变复杂,反映西南季风逐渐增强,其波动幅度也逐渐变大,并于0.991—0.342Ma期间达到最强盛,其波动幅度也最大;而在2.780—2.729Ma、2.608—1.447Ma和0.342—0.118Ma期间,气候普遍相对温暖干旱,西南季风相对较弱。 | 肖霞云 沈吉 王苏民 肖海丰 童国榜 | 2009 | 古生物学报2009，48，2： | 5 |
