Abstract

With the support of RS and GIS Technology, take 1987, 2000 and 2010 s TM remote sensing images as the data source,use the man-machine interactive visual interpretation method to obtain data of Qinghai Lake watershed wetland landscape, according to the theory of landscape ecology, selection of landscape fragmentation and landscape fractal dimension, analysis of wetland landscape pattern change in Qinghai Lake watershed quantitatively. The results show, 1 the main Alpine swamp of Qinghai Lake is watershed wetland landscape. 2 Qinghai Lake watershed wetland landscape area fluctuates obviously, Changes the landscape structure. 3 1987~2000 wetland landscape area gradually decreased rapidly, Landscape fragmentation and landscape fractal dimension increased significantly. 4 2000~2010 years of wetland landscape area increased rapidly, the fragmentation of the landscape is significantly reduced, the landscape of polymerization degree enhancement.
