VARIATIONS IN THE EBINUR LAKE AREA CAUSED BY HUMAN ACTIVITIES AND CLIMATIC CHANGES
-
摘要: 新疆艾比湖地处我国西北干旱区,为典型的内陆封闭性湖泊,由于受内陆极端干旱气候及人类活动的影响,导致湖泊面积显著变化。湖泊面积变化所导致的生态环境恶化已成为制约当地社会经济发展的重要因素。以不同年份的多源遥感数据为数据源,分析了1972-2008年湖泊面积变化情况,并分析了特征年内湖泊面积变化的原因。认为气候要素中降水对湖泊面积影响较大,另外,人类活动引起绿洲变化,而绿洲农业灌溉用水对湖泊面积变化影响较大。同时,还分析了湖泊萎缩引起的湖泊水质恶化以及湖滨植被退化和区域沙漠化等环境效应,结果表明,湖泊面积是流域生态保障的重要指标,可作为反应湖泊流域生态情况的重要指标。由此提出了保护艾比湖生态环境的若干建议。Abstract: The Ebinur Lake of Xinjiang is a typical closed inland lake located in the arid region of northwestern China. Because of the arid climate and human activity, the lake area changed dramatically in the past decades. Lake area shrinkage caused by the ecological environment deterioration has become important restraining factors for the social development. Based on multi-source remote-sensing data from different years, changes in the lake area and oasis in Xinjiang (1972-2008) are analyzed, and the reasons and impact factors for the changes in typical years are pointed out. We find that precipitation is one of the most important factors, and human activity such as agriculture irrigation in the catchments shown as oasis change has great influence on lake area. Furthermore, the detailed influences on the water quality, desertification and waterside vegetation are discussed, and a conclusion is reached that the lake area is the most important factor to ensure the nice environment of the watershed and the key index to measure the environment balance. In the end, some suggestions related to the lake protection are proposed.
