摘要
以广东省广州市越秀区为例,利用层次分析法和专家咨询法建立供需测度指标体系,并采用两步移动搜索法、服务区分析法、OD成本矩阵法等展开公园绿地供给评价。采用区位熵方法对总人口密度及不同群体人口密度展开居民需求评价,借助协同度模型得出公园绿地空间供需协同度及供需关系评价。结果表明:越秀区公园绿地空间整体供给水平高,但不同街道供给差异大;整体需求水平高且呈横向带状分布;供需布局不平衡,空间分异明显;供需协同度较好,但仍有部分供需失调及供给不足区域亟需优化。
Taking Yuexiu District,Guangzhou,Guangdong as an example,the index system of supply and demand measurement is established by analytic hierarchy process method and expert consultation method,two-step mobile search method,service area analysis method and OD cost matrix method are used to evaluate the park green supply.Using the location entropy method,the resident demand is evaluated for total population density and population densities of different groups;using the coordination model,the evaluation of supply-demand coordination degree and supply-demand relationship of park green space is obtained.The results show that the overall supply level of park green space in Yuexiu District is high,but the supply of different streets varies significantly.The overall demand level is high and distributed in a horizontal strip shape.The spatial difference of unbalanced distribution of supply and demand is obvious.The coordination degree of supply and demand is benign,but some areas with supply-demand imbalance and insufficient supply would be optimized necessarily.
