摘要
Abstract
The reachability of urban green space is an important factor affecting the efficiency of green land use,and also is an important basis for the construction of green space. Taking the central urban area of Changchun city as the researched area, based on the data of urban residential land and population distribution,using GIS spatial analysis technique,using the population gravity center model based on population weight,the author simulated the pattern of newly-increased green land in the researched area, generated the new spatial distribution of green space pattern by using the method of buffer analysis,and quantitatively ana-lyzed and evaluated the results. The optimized scheme of park green space pattern in Changchun increased the reachable popula-tion of park green space by 50.3 percent,and enhanced the reachable park green space area by 22.5 percent under the condition of increasing park green space area by 5.5%.关键词
