Ecological Water Requirement Estimates for Natural Vegetation in Arid Areas

Abstract:

Data of natural vegetation coverage in the Central Asia and Xinjiang of Chinese in 2005 was obtained by statistical analysis on MODIS Land cover data, then the ecological water requirement (EWR) of natural vegetation was brought out which based on the evapotranspirtation (ET) retrieval using SEBS model and natural vegetation areas. Results showed that the total EWR of wood land and grass land during the 2005 growing season was 70.10×10⁸m³ and 3251.91×10⁸m³,respectively. It is applicable for reference in the project of regenerating ecology and rationally redistributing water resources in arid areas.
