| 摘 要： | 湖泊变迁敏感地记录着气候与环境变化的信息,是全球变化直接的反映。新疆是我国湖泊面积最多的省区之一,湖泊大多为河流的尾闾湖,易受气候和人为干扰,面积变化大。文中利用MODIS数据,运用NDVI等模型,通过其波段组合并采用目视解译的方法对全疆主要湖泊2000～2009年湖泊面积统计,并通过全疆17个台站降水量、积温、湿润度...

| Abstract: | Changes of lakes record the information of climate and environmental variations sensitively,which is a direct reflection of global change.Xinjiang is one of the China's largest lake area.Most of the lakes are the trail of rivers,which are vulnerable to climate and human interference,and the area change is big.By using MODIS data,NDVI and other models,through its band composition and using visual interpretation,we ananlyzed the area data of major lakes in Xinjiang from 2000 to 2009.Simultaneously,the precipitation,accumulated temperature and moisture index of 17 stations in Xinjiang were analyzed for the climate change.Research showed the area of main lakes in Xinjiang appeared different degrees of change,climate change is the key factors which affect the lake area,while human factors in changing lake area has been weaken. |
