摘要
利用EOS/MODIS资料,对2004年春季至秋季间分布在甘肃省河西境内的2个面积最大的水库———红崖山水库、双塔水库和位于内蒙古额济纳旗的东、西居延海湖泊的水体面积进行监测计算,并与近年同期平均值进行了对比分析,结果表明疏勒河、石羊河及黑河流域下游的水库湖泊水体面积都有不同程度的减小。
Using the EOS/MODIS data, the water areas of eastern and western Juyan Lake in Ejinaqi, as well as Hongyashan and Shuangta reservoirs, which are the biggest in Gansu province, were monitored and calculated from spring to autumn in 2004, and a contrast analysis was done by comparing with average values of the latest 3 years in the same period. The results show that the areas of reservoirs and lakes locating in the downriver of Heihe, Shiyanghe and Shulehe valley have decreased in different degree, and this means the environment is deteriorating in these areas.
