基于GIS的城市绿地景观可达性研究——以通化市中心城区公园绿地为例

Accessibility Analysis of Urban Parks Based on GIS:Taking the Central Area of Tonghua as an Example

空间可达性是评价城市绿地系统布局合理性以及绿地空间与人居活动关联度的重要评价手段。该文选用基于网络分析法的城市公园绿地可达性分析方法作为表征通化市中心城区公园绿地可达性的重要依据,在GIS空间中实现对通化市公园绿地信息的提取、整合、分析,进而对通化市中心城区公园绿地的服务效能进行评价。为使得分析结果更为直观,采用2009年和2015年两年的公园绿地数据作为基础数据进行景观可达性的对比分析,总结之前公园绿地的建设状况,发现问题并对今后的公园绿地建设提供意见。

Spatial accessibility is an important, means of evaluating the rationality of urban green space syst.em layout and the correlation between green space and living activities. In the paper, we select urban park green space accessibility analysis method based on netwt^rk analysis as the vital basis of representing the park green space accessibility of Tonghua central area. Besides, the park green space intermation is extracted, integrated and analyzed in the GIS space, and its service efficiency is evaluated. To make the results more intuitive, we use the park green space data in 2009 and 2015 as the essential data for the comparative analysis of the landscape accessibility. Finally, we sum up the construction of the previous park green space,, and find out problems and put, forward some suggestions, so as [o provide reference [or the, constructi（m of park green space in the future.
