摘要
为更准确地反映哈尔滨公园绿地的防灾避险功能服务情况,推动城市公园应急避险功能布局的合理化和公平化,现从公共服务设施区位理论出发,基于GIS分析平台从可达性和服务效率2个角度对哈尔滨公园绿地的防灾避险功能服务状况进行评价。结果表明:通过可达性分析得到研究区在500 m和1 000 m服务半径范围内分别只有13.67%和28.99%的区域能够在发生灾害时快捷迅速地到达公园绿地;通过基于人口的服务效率分析得到在500 m和1 000 m服务半径范围内分别只有23.8%和51.89%的研究区人口能够在发生灾害时及时到达公园绿地避险。由此可知,哈尔滨具有防灾避险功能的公园绿地数量不足且空间分布不均匀,哈尔滨公园绿地防灾避险服务的公平性和服务效率均有待提高。
To reflect green space of Harbin city parks＇ service situation more accurately, bringing a great rationalization and equity to distribution. The article evaluated the green space of Harbin city parks＇ service situation based on both angles of accessibility and service efficiency by GIS-based analysis platform. The results showed that using accessibility analysis showed under 500 m and 1 000 m service radius only 13.67% and 28. 99% of the study area can reach green space of Harbin city parks easily when the disaster happened;and only 23. 8% and 51.89% of the citizens can get to the disaster-prevention parks when using analysis of service efficiency. The number of Harbin＇s disaster-prevention based green space is not enough, the equity and service efficiency of Harbin＇s green space disaster-prevention functions is hoped to be improved.
