| 摘 要： | 利用2005-2008年250 m×250 m的EOS/MODIS卫星资料，通过预处理、几何校正，在C++环境下，进行水体判识与面积计算，对巴里坤湖区面积进行了计算，得到了逐旬的遥感动态监测数据，结果表明：随着温度和降水的季节性改变，巴里坤湖面积呈现周期性变化，自11月下旬湖区进入结冰期直至次年3月中下旬逐步解冻，5-6月湖区面积出现第1次峰值，为融雪积水，7-8月也会出现一次峰值，为降水所致。

| Abstract: | 250 m×250 m EOS/MODIS satellite information between 2005 and 2008 was pretreated and geometrically adjusted. Water area of Barkol Lake was calculated by using C++ program and remote sensed monitoring data was obtained by every ten days. The results showed that with the seasonal change of temperature and rainfall, the area of Barkol Lake varied accordingly. The lake was frozen from November to March and thawed after. The first maximum value of lake area was occurred in May or June, which was caused by snow melting; the second maximum value was observed in July or August, which was caused by the rainfall. |
