| Abstract: | North-western plateau grassland in Sichuan is one of the five big pastoral areas.Since the past semicentury,serious deterioration and desertification of the local grassland came into being.Moreover,the deterioration and desertification in Ruoergai-Hongyuan of its north caused particular attention,and author also did several investigations.In recent years,similar situation was found in Litang which located in the plateau's south.According to the existing data,author did some preliminary study,and the results showed that the desertification area of the grassland nearby the county seat of Litang enlarged 2.45 times,increased to 1495.70 hm2,accounting for 10.20% of the total area.Furthermore,the degree of desertification there was nothing less than that in the north area,which should cause more attention. |
