| 摘 要： | 随着城市化进程的发展,大城市郊区绿地资源空间分布不均匀现象日益突出,公园绿地空间可达性分析可以为城市郊区公园绿地空间布局规划提供科学依据。以2005年南京市郊雨花台区公园绿地为研究对象,运用2步移动搜索法（2SFCA）,计算研究区公园绿地可达性指数,并通过在研究区南部增加5个湿地公园的方式,进行规划前后公园绿地空间可达性改善状况的对比分析。研究结果表明：①雨花台区靠近主城区和风景区的北部、东南部可达性指数较高,中部指数中等,而南部偏远农村地区可达性指数偏低;②规划后公园绿地可达性指数低、中等部分几乎全部消失,研究区公园绿地可达性指数将提高到一个较高层次;③规划后,研究区域公园绿地不平衡分布状况得到极大改善,符合雨花台区生态环境建设发展方向。

| Abstract: | With the rapid development of urbanization,the unevenly spatial distribution of green space in suburb parks is increasingly prominent.Research on spatial accessibility analysis of green space in suburb parks can provide scientific basis for spatial planning of green space in metropolis.Green space in Yuhuatai district of Nanjing city in 2005 was chosen as the research object,and two step floating catchment area method（2SFCA）was applied to do spatial accessibility analysis of green space in the case study area.Then five new wetland parks in the southern part of the study area were added to improve spatial accessibility.The results show that： ①the accessibility index in northern and southeastern part of the case study area which is either near the urban area or scenic spot is high,the accessibility index in middle part is medium,but the index in southern remote rural area is low;②after planning,the area with low or medium accessibility index almost disappear,making spatial accessibility of the whole study area increase to a higher level;③after the planning is realized,the spatial distribution of green space in suburb parks will get balanced,which is consistent with the ecological environment construction strategy of the study area. |
