中文摘要	在对柴窝堡地区多期陆地资源卫星、中巴资源卫星以及Modis遥感影像解译基础上,结合器测气象资料、地下水以及湖泊水深等数据,对柴窝堡湖面积变化及其环境效应进行了研究。结果表明:20世纪70年代以来湖泊总体呈下降趋势,但到20世纪末至21世纪初期受流域降水增加影响,湖泊面积出现一定程度的扩展,面积最高达到约29.5 km2（2002年）。近几年,由于流域降水减少,人为提取地下水量增加,湖泊水位出现快速下降。2008年湖泊水位比1971年下降了约2.2 m,湖泊面积缩小到约27 km2。由于柴窝堡湖为陡岸平底型湖泊,湖泊水位下降初期引起的面积萎缩并不明显,但当前湖泊处于面积快速萎缩转折的水位。随着湖泊水位的进一步下降,将会引起面积的快速收缩,以至干涸,从而加剧湖泊周边地区土壤碱化、沙化、植被退化等生态环境问题,对区域社会经济发展产生重要的影响。
英文摘要	Chaiwopu Lake is located at Chaiwopu Basin of Urumqi in the arid regions of Northwest China.The lake area change and its environmental effects were studied by interpreting remote-sensing images including MSS (multispectral sensing system),Landsat TM/ETM,Modis and CBERS (China - Brazil earth resources satellite)from 1975 to 2008.The factors driving lake area change are also analyzed using data from Urumqi and Dabancheng meteorological stations,groundwater level and lake water depth data.By measuring the relief map (1:1 000 000),lake area of 1971 is 30 km2 including the adjoining west small lake.Lake surface area declined from 1971 to 2008 generally,but the lake area enlarged to 29.5 km2(in 2002)during the early 2000s because of the enhanced regional precipitations,successively,lake area declined with the declined regional precipitations and decreased ground water runoff,because Urumqi water resource projects abundantly draw out ground water for northern and western Chaiwopu lake.Lake surface level in 2008 is 1091.66 m,which is lower than the level of 1971 by 2.2 m.Lake area has declined to 27 km2.Because Chaiwopu lake has a steep-shore and flat-bottom morphology,the scale of lake surface area change is not obvious in the initial periods of lake level declining,however,the lake level is in the turning point now,successively,lake area will shrink sharply.In the arid region,lake is very important in maintaining regional ecological environment,so the shrinked or disappeared water surface will result in some environmental problems such as total dissolved solid increased,soil and vegetation degenerated,etc,which will deeply affect the regional socio-economic developments.
