摘要
以河南省郑州市四环以内为研究区域,采用电子导航地图的POI数据与GIS空间分析技术,选取缓解热岛效应、休憩娱乐、防灾避险3种城市绿地服务功能,将其服务空间与POI密度图进行叠置分析,探索一种全新的研究方法并对城市绿地服务空间分布进行研究。结果表明:区域内绿地缓解热岛效应、休憩娱乐、防灾避险3种功能服务空间分别占研究区的57.71%,47.36%,68.03%;POI中密度分布区绿地服务水平最高,较低密度区次之,高密度区和极高密度区绿地服务水平较低,绿地服务范围重叠和服务盲区并存;郑州市四环以内城市绿地系统存在服务空间分布不均衡、服务供给不足等问题。以城市规划学与风景园林学理论相结合为城市绿地规划设计实践提供优化策略。
Taking the Fourth Ring of Zhengzhou City,Henan Province as the research area,using the POI data of the electronic navigation map and GIS spatial analysis technology,three urban green space services are selected for alleviation of the heat island effect,recreation and entertainment,and disaster prevention and avoidance,and the service space is compared with the POI heat map.Overlay analysis of the service space and POI heat map,and establish a new research method to evaluate the rationality of urban green spatial distribution.The results show that the three types of urban green space service areas account for 57.71 %,47.36 % and 68.03 % of the study area,respectively.According to the analysis results,the urban green space system within the fourth Ring Road in Zhengzhou has problems such as unbalanced service space distribution and insufficient service supply.On the basis of the study on the spatial distribution of green space service,this paper tries to combine the theory of urban planning and landscape architecture to provide an optimization strategy for the urban green space planning and design practice.
