Paper Abstract

This research revealed the overall trend of change in south Qiangtang, Namco watershed by extracting multi-temporal TUPU using interpretation results of several remotely sensed images from1992 to 2005. The result of TUPU deriving revealed that there has been a sharp augment in lake area extension in the study area during the past 15 years. Typical lakes were used to analyze some characteristics of the change. The steady increase of area was extracted as well. By analyzing the variation information from multi-temporal TUPU together with the meteorological data, the rapid extension of lakes in Tibet Plateau are attributed to several factors, such as the average annual precipitation, which could have affected area of the lakes indirectly by reacting to the movement of glaciers.
