文摘内容 Based on GIS technology,from the perspective of landscape ecology and by taking Dianbai County for example,the paper had made landscape layout division according to land use types and studied dynamic change of local land use through indexes’ change.The result showed that coastal mudflat in Diantai County had increased obviously while water area had decreased substantially and other lands also decreased in a way from 2005 to 2009.The number of land use patches increased,fractal dimension and isolating degree appeared to be in increasing trend,and diversity and evenness degree presented to be in decreasing trend.Spatial heterogeneity of landscape layout reduced,and dominance and fragmentation degree of it increased.Human activity made larger interference on landscape layout.
