| 摘 要： | 以青藏高原70年代MSS影像数据与2000年ETM影像数据为主要信息源，基于RS和GIS技术研究近30年来青藏高原湖泊面积的动态变化。结果表明：近30年来在部分湖泊面积减小的情况下青藏高原湖泊总面积和数量是增加的，其面积增加3316．52km^2，但在各区域具有不同的变化趋势。

| Abstract: | Taking MSS image data in 1970's and ETM image data in 2000 as the major data source,the authors studied the dynamic changes of lake areas in Qinghai-Tibet Plateau during the recent 30 years by using RS and GIS technology.The results indicate that the total area and the numbers of the lakes in the Qinghai-Tibet Plateau have increased remarkably with expanding 3 316.52 km2 in total,although the areas of quite a few lakes have been decreasing in the past 30 years.However,the change trends are different in various areas of the Qinghai-Tibet Plateau. |
