摘　　要：选取长春城市公园绿地作为研究对象,根据研究区遥感影像图,结合吉林统计年鉴,利用ArcGIS的网络分析模块(Network Analysis),得出长春市公园不同时间成本的可达性范围图。评价了长春城市公园的空间分布和服务情况,分析了长春及其各行政区城市公园绿地的可达性。结果显示,研究区只有10.6%的居民能够在15 min内到达公园,28%的居民能够在30 min内到达公园。长春城市公园数量不足并且空间上分布不均匀。南关区和朝阳区公园的可达性最好,绿园区和宽城区次之,二道区公园可达性最差。Changchun urban park green space is selected as the research object. According to the remote sensing images of the study area and Jilin statistical year book,the accessibility maps of Changchun urban parks in different time costs are obtained using network analysis model of Arc GIS. The spatial distribution and service of Changchun urban parks are evaluated and the accessibility of urban parks in Changchun and its administrative districts are analyzed. The results show that only 10. 6% of the residents can reach parks within 15 minutes,and 28%of the residents can reach parks within 30 minutes. The number of city parks in Changchun is insufficient and the space is not evenly distributed. The parks in Nanguan and Chaoyang districts have the best accessibility,followed by that of Lüyuan and Kuancheng,with Erdao as the worst.
