摘要

By using TM remote sensing images of Baiyangdian Wetland in 1989,1999,2003 and 2004,taking the water area between Anxin County and Cangzhou where most of Baiyangdian Wetland water body lies for landscape classification,changes in landscape pattern of Baiyangdian before and after the water supplement were analyzed with landscape indexes calculated by Fragstats3.3. The results showed that after the water supplement,from the perspective of landscape cell index,fractal dimension of major ecosystems in Baiyangdian decreased to some extent;from the perspective of landscape diversity index,diversity index of the study region also decreased,which demonstrated that ecosystem diversity in this region reduced,land cover grew to simplification;and the decreasing evenness degree of the study region also showed the uneven development of its ecosystems. That is to say,water supplement has brought favorable ecological changes to the eco-environment of Baiyangdian,which has further optimized the health condition of ecosystems in this region.
