Abstract

This paper emphasized the relationship between environment and water, taking ecological demand water (EWD) in the Qaidam Basin, an inner basin in northwestern China, as a key issue to discuss based on landscape mapping. First, the spatial heterogeneity of ecosystem can be reflected well by landscape pattern; landscape patterns adjust closely with environmental changes; finally, water condition is the key ecological factor for landscape pattern in the arid region. The landsat TM image of 1:100,000 on September 22, 1996 was calibrated with topographical map of the same scale, and then landscape patterns were interpreted and mapped
