Trend analysis on land degradation in Zoige Plateau based on landscape structure methods

In this research,the data of landscape types of Zoige Plateau in two periods of 1990 and 2000 based on RS and GIS technology was obtained,from which the dynamic transition probability matrix of landscape types was obtained.At the same time,a transferred model of landscape structure was employed to predict the landscape degrading tendency.The results show that high coverage grassland,woodland,water areas,swamp decreased continuously and the land of residence,sandy and unused lands kept increasing,while the changing tendencies of mild,severely degrading grassland and farmland were relatively complex.It can be concluded that landscape degradation will be further deteriorated without any environmental protection.
