| 摘 要： | 遥感技术由于能够快速、 宏观的获得研究区域的数据, 已成为青藏高原热融湖塘动态监测的重要技术手段. 基于野外现场调查和SPOT-5、 QuickBird两种高分辨率遥感卫星数据的特性分析, 结合影响青藏高原热融湖塘发育的一系列特征因素, 探讨了最适合于青藏高原热融湖塘动态监测的高分辨率遥感数据的纠正、 融合和信息提取方法. 应用该方法对2006—2009年间北麓河盆地北侧的红梁河至秀水河段公路沿线局部63 km2范围的热融湖塘进行了变化特征分析, 结果表明该区的热融湖塘个数和总面积在研究时段都有所增加, 其中湖塘由70个增加到75个, 湖塘总面积增量19.65%. |

| Abstract: | Remote sensing technology has become an important tool to dynamically monitor the processes of thermokarst lakes in the Tibetan Plateau, from which macroscopical spatial data can be obtained rapidly. In this work, the data processing methods including data correcting, data fusion and information extraction were proposed and discussed based on the characteristics of the high spatial resolution remote sensing data from QuickBird and SPOT-5, combining with character factors of the thermokarst lakes in the Qinghai-Tibet Plateau. Furthermore, a most suitable procedure was applied to investigate the change of the thermokarst lakes in a limited range, 63 km2 in area, located in the north of the Beiluhe River basin from 2006 to 2009. The area is from Honglianghe to Xiushuihe along the Qinghai-Tibet Highway. The results show that the amount and total area of the thermokarst lakes have slightly increased. |
