Analysis of spatial grain effects on landscape pattern in Chancheng district of Foshan city——Analysis on grain effect
Abstract：Taking Changcheng district of Foshan city as the object and the classification and use of the land in Changcheng district as the basis of our research,we use GIS software,landscape pattern software（Fragrats3.3） and Excel as tools to analyze the effect of the changes in spatial grain and the effect of grain size on landscape pattern between the old urban area and Nanzhuang district from the perspectives of the landscape-and the class-level so as to provide some theoretical reference for the landscape indices calculation with suitable grain size and size shifting.We found that the indices of landscape pattern change significantly with the increase of grain size.To make it exact,for the landscape-level in Changchen district,the appropriate spatial resolution is 5,20～40 and 120～140 m;in the old urban area,10,20～40 and 120～140 m;and Nanzhuang district,5,70 and 110 m while for the class-level in Changchen district and the old urban areathe appropriate spatial resolution is 10 or 120～140 m and in Nanzhuang district,10,20 or 120～150 m.
