Optimization of City Landscape Pattern Based on GIS in Lu'an City

Sun Xianbin,Li Chuanwu,Fu Xianlan(Department of Urban Construction and Environmental Sciences,Wanxi University,Lu'an,Anhui 237012)  
Landscape pattern and ecological processes is the key topic of landscape ecology.Landscape pattern optimization based on ecological function and process is one of the key methods to improve landscape efficiency and stability.With GIS technology,the paper makes a quantitative analysis of Lu'an City landscape pattern,and the resistance model is employed to optimize landscape pattern.Based on an accumulative cost distance model,ecological sources and cost path,the optimization of landscape pattern of ecological sources and corridors is established.Strengthening the protection of core sources and improvement of landscape connection is the key to the optimization of city landscape.The research provides scientific basis to utilization of urban land and ecological protection.
