【摘要】：公园绿地空间布局和结构会影响到城市居民的健康和城市生态格局,对城市规划建设至关重要。因此,评价城市公园绿地的空间分布具有重要的现实指导意义。本文以武汉市七个中心城区为例,采用含有距离衰减系数的重力型两步移动搜索法(G2SFCA),探讨居住区尺度下不同等级公园绿地的空间公平性。结果表明:(1)距离因素会改变公园绿地的空间公平性,并且不同等级公园绿地的空间公平性变化存在差异;(2)武汉市中心城区公园绿地空间公平性评价结果并不理想,"严重不公平"级别所占面积比重始终比较大;(3)区域性公园绿地的空间公平性要优于全市性公园绿地的空间公平性;(4)公园绿地空间分布呈现不均衡特征,空间公平性的区域差异较大。街道人口数量、公园绿地数量、公园绿地的服务能力是造成其空间公平性区域差异的重要因素。因此,应该结合人口需求科学地规划公园绿地的数量和等级,以实现公共资源的有效利用。
[Abstract]:The layout and structure of park green space will affect the health of urban residents and the urban ecological pattern, which is very important to urban planning and construction. Therefore, the evaluation of urban park green space distribution has an important practical significance. Taking the seven central urban areas of Wuhan as an example, a gravity two-step moving search method (G2SFCA) with distance attenuation coefficient is used to study the spatial fairness of park green space of different grades in residential area. The results are as follows: (1) the distance factor will change the spatial fairness of the park green space, and there are differences in the spatial equity change of different levels of park green space; (2) the evaluation result of the fairness of the park green space in Wuhan city center is not ideal, and the proportion of the area occupied by the grade of "serious unfairness" has always been relatively large; (3) the spatial fairness of regional park green space is better than that of citywide park green space; (4) the spatial distribution of park green space is unbalanced, and the regional difference of spatial fairness is great. The number of street population and the service ability of park green space are the important factors that cause the regional difference of spatial equity. Therefore, the number and grade of park green space should be scientifically planned in order to realize the effective utilization of public resources.
