Abstract

Based on the theory and method of landscape ecology and QuickBird satellite images,an integrated approach of GIS/RS was employed to analyze the urban forest landscape pattern of Maanshan City.The study area consisted of three districts,which cover the whole build-up area with 63.08 km~2.The landscape pattern of urban forest in the three districts were analyzed and compared by five landscape metrics,including urban forest cover percentage,patch density index,isolation index,landscape diversity index and patch shape index.Sandard deviation,entropy weight and CRITIC methods were applied for comprehensive assessment of urban forest landscape pattern.The three methods show the same sequence of the urban forest landscape pattern: Yushan DistrictHuashan DistrictJinjiazhuang District.The results are helpful for optimizing the urban forest pattern at landscape level.
