Abstract:

Our purpose is to analyze the difference of the settlements landscape under several spatial granularities.In this study,we combined GIS and landscape analysis method,took the land use data of Zhenjiang in 2009，calculated spatial transfer probability between the settlements landscape and others and landscape pattern indices based on Rule of Centric Cell and Rule of Maximum Area.The results are as follows.(1) Relative error of each landscape pattern under Rule of Maximum Area was bigger than the others.(2)In terms of the changes of the settlements landscape,the landscape indices,containing Patch Density,Aggregation Index and Patch Cohesion Index were reducing as the granularity rised,while other indices,PerimeterArea Fractal Dimension,Largest Patch Index and Euclidean NearestNeighbor Distance were raising.It indicated that the patches of settlements pattern became less fragmented,the area became bigger,the patches trended to be into the group,and the spatial distribution became more discretely.(3)The change of the settlements pattern indicated that Rule of Maximum Area outstanded overall distribution law,while Rule of Centric Cell expressed spatial distribution characteristics.(4)Scaling Effect of Rule of Maximum Area was related to the special neighboring property and area structure
