Abstract

In order to acquire objectively spatial-temporal processes of grassland degradation, MSS images in the mid and late 1970s, TM images in the early 1990s and TM/ETM images in 2004 were used. Grassland degradation in the Three-River Headwaters (TRH) region was interpreted through analysis on RS images in 2 time series, then the spatial and temporal characteristics of grassland degradation in the TRH region were analyzed since the 1970s. Because grassland degradation had obviously regional differences in the TRH region, it could be regionalized into 7 zones, and each zone had different characteristics in type, grade, scale and time process of grassland degradation
