摘要
选取1991、2001、2010年遥感影像数据(Iandsat TM/ETM),通过几何校正等预处理,在地理信息系统平台上对巴里坤湖区面积进行水体辨识与水域面积计算。同时,结合1981-2011年研究区站点的气象数据,探讨其对气候变化的基本响应状况。结果表明,1991年巴里坤湖总水域面积为97.47 km2,2001年为45.65 km2,2010年为36.18 km2,湖泊水域面积萎缩,是气候因素和人为因素共同作用的结果。
Through the geometric correction of pretreatment, Barkol Lake area was discriminated and the water area in geo- graphic information system platform was calculated using the remote sensing images chosen from 1991, 2001 and 2010 land- sat（TM/ETM）. Combined with the meteorological data of 1981-2010, the response of Barkol lake area to the climate change was analyzed. The results showed that Barkol Lake area became less and less, such as in 1991 （97.47 km2）, 2001（45.65 km2） and 2010（36.18 km2）,caused by climate factors and human factors.
