| 摘 要： | 利用多期遥感影像,对青藏高原南羌塘地区纳木错湖泊流域北部进行解译,提取了多时相地学信息图谱,发现1992-2005年间,湖泊面积扩张且整体变化呈加快趋势。分析了研究区内典型湖泊的变化特征,确定了稳定增加的湖泊面积。通过多时相地学信息图谱检测的变化信息与区内多年气象数据的复合分析,探讨了湖泊变化与气候变化的响应关系。

| Abstract: | Researches were performed to reveal the overall development trend of south Qiangtang area by extracting multi-temporal TUPU using interpretation results of several remote sensing images from 1992 to 2005. The results of TUPU deriving reveal that there has been a sharp augment in lake area extension of the study area-Namco watershed of south Qiangtang-during the past 15 years. The typical lake was used to analyze some specific variation features, and the steadily increased area was extracted as well. Based on analyzing the variation information from multi-temporal TUPU together with the meteorological data, the authors used some factors to interpret the rapid extension of lakes in Qinghai-Tibet Plateau, such as the average annual precipitation, which could affect the increase of lake areas indirectly by reacting on the movement of glaciers. |
