【摘要】：公園綠地空間布局和結(jié)構(gòu)會(huì)影響到城市居民的健康和城市生態(tài)格局,對(duì)城市規(guī)劃建設(shè)至關(guān)重要。因此,評(píng)價(jià)城市公園綠地的空間分布具有重要的現(xiàn)實(shí)指導(dǎo)意義。本文以武漢市七個(gè)中心城區(qū)為例,采用含有距離衰減系數(shù)的重力型兩步移動(dòng)搜索法(G2SFCA),探討居住區(qū)尺度下不同等級(jí)公園綠地的空間公平性。結(jié)果表明:(1)距離因素會(huì)改變公園綠地的空間公平性,并且不同等級(jí)公園綠地的空間公平性變化存在差異;(2)武漢市中心城區(qū)公園綠地空間公平性評(píng)價(jià)結(jié)果并不理想,"嚴(yán)重不公平"級(jí)別所占面積比重始終比較大;(3)區(qū)域性公園綠地的空間公平性要優(yōu)于全市性公園綠地的空間公平性;(4)公園綠地空間分布呈現(xiàn)不均衡特征,空間公平性的區(qū)域差異較大。街道人口數(shù)量、公園綠地?cái)?shù)量、公園綠地的服務(wù)能力是造成其空間公平性區(qū)域差異的重要因素。因此,應(yīng)該結(jié)合人口需求科學(xué)地規(guī)劃公園綠地的數(shù)量和等級(jí),以實(shí)現(xiàn)公共資源的有效利用。
[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.
