摘　　要：基于Landsat-8影像数据,采用ANDWI_ISODATA法对2013─2020年艾丁湖的湖泊面积进行了提取,总体分类精度达到98%以上;在此基础上,根据湖泊干涸期湖底ASTER GDEM数据,对2013─2020年艾丁湖的湖泊水量进行了估算,并分析了艾丁湖湖泊水量的变化特征及其对农业用水的影响。结果表明:艾丁湖湖泊面积和水量的年际变化整体上均呈现出先升高后降低的变化趋势,均在2017年达到最大值,分别为31.17 km^(2)和3369.17万m^(3);湖泊水量的年内变化呈现春季储水、夏季干涸、秋季和冬季回水的规律;在春冬季,湿地保育区水量丰盈,直接与主湖区形成整体湖泊,呈现“J”形;在农作物生长季的4─6月份,艾丁湖湖泊水量对农业用水的补给占到35%左右,而降水占农业用水的比例只有1%左右。Based on Landsat-8 image data,ANDWI_ISODATA method was used to achieve accurate extraction of lake area,and the overall classification accuracy reached more than 98%.On this basis,combined with ASTER GDEM data of lake bottom during lake dry period,accurate estimation of seasonal lake water volume was realized,and the variation characteristics of water volume in Aiding Lake from 2013 to 2020 were further analyzed.The results showed that the lake area and water volume generally increased first and then decreased,and both reached the maximum in 2017,with 31.17 km^(2)and 33691700 m^(3).The overall changes of the lake showed that water was stored in spring,dried up in summer,and returned in autumn and winter.In spring and winter,the wetland conservation area was full of water,and directly formed an overall lake with the main lake area,showing a“J”shape.From April to June,during crop growing season,the water supply of Aiding Lake to agricultural water accounted for about 35%,while precipitation accounted for about 1%.
