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占额济纳旗的东、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。
关键词: MODI S资料, 水库湖泊水域, 河西内陆河
Abstract:
Using the Shuangta reservoirs,EOS/MODIS data, the water areas of eastern and western Juyan Lake in Ejinaqi, as well as Hongyashan and Shuangta 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 arid lakes locating In the downrlver of Helhe, Shlyanghe arid Shulehe Valley have decreased In different degree, arid this the enVlTOnment 1S deteTlOTatlng In these areas.
Key words: MODIS data, reservoris and lakes, water area, contrast analysis
