U.S.-China Cooperative Research: Holocene Environmental History of the Kunming Lake District as Recorded in Lake Sediments

该奖项支持中美生态学家、地球化学家和孢粉学家合作研究中国西南云南高原特定湖泊生态系统的沉积历史。研究了云南五个湖泊的岩心，以确定生态系统对自然和人为压力的响应速率。将测量湖泊沉积物中水生和陆生、生物和化学化石在同位素定年水平之间的积累变化率。中国的这一地区因其植物区系与美国东南部相似而闻名。它也是世界上最古老的集约化农业中心之一。通过这个合作项目，希望我们对农业、工业和城市发展的环境后果的理解将得到改善。

This award supports collaborative research between teams of US and Chinese ecologists, geochemists, and palynologists on the study of sedimentary histories of selected lacustrine ecosystems of the Yunnan Plateau in southwest China. Cores collected from five Yunnan lakes will be studied to determine rates of ecosystem response to natural and anthropogenic stresses. Measurements will be made of changing rates of accumulation of aquatic and terrestrial, biological and chemical fossils between isotopically dated levels in lake sediments. This part of China is well known for its floristic similarity to the southeastern US. It is also one of the world's oldest centers of intensive agriculture. Through this cooperative project, it is hoped that our understanding of the environmental consequences of agricultural, industrial, and urban development will be improved.
