中文摘要: 干旱区湖泊变化与人类活动、气候变化的关系研究是地理学、生态学、历史地理学等研究者共同关注的重要科学问题。针对新疆水资源保护和利用中亟需解决的实际问题和科学问题,结合过去全球变化(PAGES)研究的最新趋势,本项目以过去300年新疆平原区湖泊演变为研究对象,通过对历史文献、古地图、地形图、现代统计数据、遥感影像等多源数据的搜集、整理和集成分析,重建湖泊演化序列、人口和耕地变化序列、气候变化序列,对比、统计、综合分析300年时间段内湖泊动态变化的时空特征、量化分析人文因素和气候因素对湖泊演变的影响,揭示湖泊演变对气候变化的响应。预测未来全球变化下,湖泊演变的方向,为区域水资源保护和利用提供政策制定的科学依据。

英文摘要: The relationship of lake change, climate change and human activities in arid area is an important scientific issue of common concern of geographer, ecologist, historical geographer and other researchers. For protection and utilization of water resources in Xinjiang is an urgent need to be solved in practical issues and scientific issues, this project designed to reconstruct the evolution sequences of lakes on the plain area in Xinjiang, the population change, cultivated land change, climate change through comparing and comprehensive analyzing the historical documents, ancient maps, topographic maps, statistics, and remote sensing images. The aim of this project is to reveal the spatial and temporal change characteristics of the Plain Lakes in Xinjiang of the past 300 years and quantitative analysis of the evolution of the human factors and climatic factors on the lakes, and then predict the direction of the lakes evolution in the future globe change and provide the scientific basis for policy formulation of protection and utilization of water resources in Xinjiang.
