| 1 | 萨拉乌苏河流域MGS3地层段腹足类动物化石种类及气候环境显示文摘毛乌素沙漠萨拉乌苏河流域米浪沟湾剖面与MIS3相当的MGS3地层段中33LS,35LS,37FL和39LS的腹足类—陆生蜗牛和淡水螺类化石,经鉴定为11种,隶属于8科10属.可以划分为:(1)旋螺属-土蜗螺属组合,主要成员是凸旋螺Gyraulus convexiusculus,西伯利亚旋螺Gyraulus sibiricus,小土蜗Galba pervia,奇异土蜗Galba superegra Gredler等;(2)瓦娄蜗牛属组合,主要成员有伸展瓦娄蜗牛Vallonia patens,白云石虹蛹螺Pupilla muscorum,浅圆盘螺Discus pauper等陆生螺类.依据年代测试结果和这些化石现生种的生活习性、栖息环境及地理分布,研究认为,33LS,35LS,37FL,39LS依次距今为26000,29000,33000和38000a,其在时间与气候特点上与格陵兰冰芯GRIP-4,5,6,10间冰段具有较好的对比关系,33LS,35LS,39LS代表了非常温暖湿润时期,37FL次之;MGS3记录的这4个时期的气候波动与MIS3间冰阶全球气候背景下东亚夏季风对毛乌素沙漠的强烈影响有关. | 李保生 陈德牛 David D.Zhang 温小浩 邱世藩 欧先交 杜恕环 牛东风 杨艺 叶建萍 郭云海 | 2007 | 中国科学(D辑)2007，37，12： | 13 |
| 2 | 萨拉乌苏河流域MGS5层段CaCO_3记录的末次间冰期东亚季风与沙漠环境演化显示文摘毛乌素沙漠萨拉乌苏河流域米浪沟湾剖面时代上属末次间冰期的MGS5层段可以进一步划分为5a—5e亚段。其中5a,5c和5e亚段以河湖相和古土壤为主要特征,其CaCO_3含量主体呈现峰态;5b和5d亚段以风成沙丘砂沉积为主,CaCO_3含量主体呈现谷态。研究表明,末次间冰期毛乌素沙漠冬季风盛行时期,沙丘砂强烈堆积,CaCO_3大量迁移;夏季风盛行时期河湖相和古土壤发育,CaCO_3大量聚集。研究还发现,MGS5各个亚段CaCO_3记录的冬夏季风环境与格陵兰冰芯氧同位素5a 5e亚段在时间—气候性质上的变化节奏相当一致。这可能说明,末次间冰期毛乌素沙漠的演化主要受北半球冰量增减导致的东亚冬、夏季风强弱所控制。 | 杜恕环 李保生 David D.Zhang 牛东风 温小浩 陈德牛 欧先交 杨艺 司月君 赵欣楠 | 2009 | 自然科学进展2009，19，11： | 8 |
| 3 | Two centuries of April-July temperature change in southeastern China and its influence on grain productivity显示文摘China is a traditional agriculture based country and one main region for crop production is southeastern China where temperature is a dominant climate variable affecting agriculture. Temperature and social disturbances both influence crop production, yet distinguishing their relative impacts is difficult due to a lack of reliable, high-resolution historical climatic records before the very recent period. Here we present the first tree-ring based warm-season temperature reconstruction for southeastern China, a core region of the East Asian monsoon, for the past 227 years. The reconstruction target was April-July mean temperature, and our model explained 60.6% of the observed temperature variance during 1953–2012.Spatial correlation analysis showed that the reconstruction is representative of April-July temperature change over most of eastern China. The reconstructed temperature series agrees well with China-scale(heavily weighted in eastern China) agricultural production index values quite well at decadal timescales.The impacts of social upheavals on food production, such as those in the period 1920–1949, were confirmed after climatic influences were excluded. Our study should help distinguish the influence of social disturbance and warm-season temperature on grain productivity in the core agricultural region of China during the past two centuries. | Jiangfeng Shi Jinbao Li David D.Zhang Jingyun Zheng Shiyuan Shi Quansheng Ge Harry F.Lee Yesi Zhao Jie Zhang Huayu Lu | 2017 | Science Bulletin2017，62，1： | 6 |
| 4 | Quantitative analysis of the impact of droughts and floods on internal wars in China over the last 500 years显示文摘Although many large-N quantitative studies have evidenced the adverse effects of climatic extremes on social stability in China during the historical period, most of them rely on temperature and precipitation as major explanatory variables, while the influence of floods and droughts on social crises is rarely measured. Furthermore, a comparison of the climate-society nexus among different geographic regions and at different temporal scales is missing in those studies. To address this knowledge gap,this study examines quantitatively the influence of floods and droughts on internal wars in three agro-ecological(rice, wheat,and pastoral) regions in China in AD1470–1911. Poisson regression and wavelet transform coherence analyses are applied to allow for the non-linear and non-stationary nature of the climate-war nexus. Results show that floods and droughts are significant in driving internal wars in historical China, but are characterized by strong regional variation. In the rice region, floods trigger internal wars at the inter-annual and multi-decadal time scales. In the wheat region, both floods and droughts cause internal wars at the inter-annual and multi-decadal time scales. In the pastoral region, internal wars are associated with floods only at the multi-decadal time scale. In addition, the multi-decadal coherence between hydro-climatic extremes and internal wars in all three of the agro-ecological regions is only significant in periods in which population density is increasing or the upper limit of regional carrying capacity is being reached. The above results imply that the climate-war nexus is mediated by regional geographic factors such as physical environmental setting and population pressure. Hence, we encourage researchers who study the historical human-climate relationship to boil down data according to geographic regions in the course of statistical analysis and to examine each region individually in follow-up studies. | Harry F.LEE David D.ZHANG PEI Qing JIA Xin Ricci P.H.YUE | 2017 | Science China Earth Sciences2017，60，12： | 3 |
| 5 | Population collapses in the pre-modern period:case study of the Fuping County, Northwest China显示文摘The pre-modern history of population change in the Fuping County(Shaanxi Province, China)during the Ming and Qing Dynasties(AD 1368-1911) was reconstructed using historical sources.The Fuping County experienced two major population collapses, i.e. the late Ming Dynasty(1550-1640 s) and the 1860-1880 s. The first one was caused by the great AD 1556 earthquake and the extreme droughts and warfare in the 1630-1640 s. The second one was caused by warfare and extreme droughts. As a whole, natural disasters, including extreme drought and great earthquake, were the key direct causes of population collapse, and climatic cooling would be a potential indirect cause. It is very interesting that population collapses occurred almost synchronously in the Fuping County and whole China, and the trends of population change were also very similar. Climate-population relationship in China would be valid at finer geographic level,and climatic cooling could be a potential indirect cause of population collapse. | Jie Fei David D.Zhang | 2017 | Chinese Journal of Population,Resources and Environment2017，15，4： | 0 |
