Water content of grassland ecosystem and its economic value in Qinghai-Tibet Plateau based on RS and GIS

摘要：

Introduction Vegetation change is a key factor influencing regional water balance.Many previous researches have shown there is a close correlation between vegetation cover and soil water.In recent years,many scholars,at home and abroad,have conducted a lot of studies on soil water,but few of them on Qinghai-Tibet Plateau.An accurate evaluation of soil water content of the grassland ecosystem in Qinghai-Tibet Plateau is important for people to understand the functioning of grassland ecosystems and effectively protect the natural grassland.This paper,in accordance with the theory of large scale ecosystem function,will effectively evaluate the soil water-holding capacity of the grassland ecosystem and its economic value in the plateau using RS and GIS.
