摘要
城市化的快速发展致使大城市城区人口规模不断扩张,以城市公园为代表的城市公共服务设施资源的需求急剧上升,但公园绿地资源与人口匹配协同性较差、配置效率低下、服务质量难以满足多样化需求等空间不公平问题日益突出。以深圳市龙岗区27个城市公园为例,利用空间句法(sDNA)与Moran′s I分析从接近度、穿行度和空间集聚差异三个方面对龙岗区城市公园空间公平性特征进行精准测度,提升城市公园空间公平性优化的空间效率。结果表明:龙岗区城市公园与人口分布存在“空间错位”现象,城市公园与城市居民需求匹配性差;龙岗区接近度呈现“南强北弱、西强东弱”的态势,区域发展不协调;龙岗区城市公园本底的路网结构整体的穿行度较差,中部区域明显高于周围其他区域;城市公园空间集聚差异表现出全局和局部接近度空间集聚显著、中心区域优势明显、穿行度空间集聚态势不清晰的特点。未来龙岗区城市公园发展中应优化本底的路网结构,提高路网密度,丰富不同等级路网间的连接方式,提升公园质量等方式改善其空间公平性水平,提高城市公园空间服务效率、协调性与人口分布的匹配程度,为深圳市公园城市建设和龙岗区公园体系规划提供新的思路。
The rapid development of urbanization has led to the continuous expansion of population in urban areas of big cities,and the demand for urban public service facilities represented by urban parks has sharply increased.However,spatial inequality issues such as poor coordination between park green space resources and population,low allocation efficiency,and difficulty in meeting diverse needs in service quality have become increasingly prominent.In order to improve the spatial efficiency of optimizing the spatial fairness of urban parks,this article took 27 urban parks in Longgang District,Shenzhen as an example,and used spatial syntax(sDNA)and Moran′s index analysis to accurately measure the spatial fairness characteristics of urban parks in Longgang District from three aspects:proximity,traversal,and spatial agglomeration differences.The results have indicated that there was a spatial mismatch between urban parks and population distribution in Longgang District,and the matching between urban parks and the needs of urban residents was poor;The proximity of Longgang District showed a trend of"strong in the south and weak in the north,strong in the west and weak in the east",and the regional development was not coordinated;The overall passability of the road network structure in Longgang District′s urban parks was poor,with the central area significantly higher than other surrounding areas;the spatial agglomeration differences of urban parks showed significant differences in global and local proximity spatial agglomeration,obvious advantages in the central area,and unclear spatial agglomeration trends in terms of traversal.In the future development of urban parks in Longgang District,the basic road network structure should be optimized,the road network density should be increased,the connection methods between different levels of road networks should be enriched,and the quality of parks should be improved to increase their spatial fairness level,enhance the efficiency and coordination of urban park space services,and match the degree of population distribution.This study will provide new ideas for the construction of Shenzhen′s park city and the planning of Longgang District′s park system.
