| Abstract: | A study on the change in landscape structure of lake wetland was conducted with the support of GIS by using remote sensing data for 1979,1989,2001 and 2008 as basic information resource.The selected indexes included number of patches,total patch area,percent of landscape,mean patch size,patch density and landscape shape.Results showed that,in the past 30 years,the wetland area of the study area increased firstly and then decreased obviously year by year with the accelerated process of urbanization.From 1989... |
