开敞空间率影响下的高密度空间聚类特征研究
Study on Spatial Clustering Characteristics of High-density Areas Under the Influence of Open Space Ratio:An Empirical Analysis of Xicheng District,Beijing,Based on Spatial Autocorrelation and Entropy Weighting
摘要
Abstract
While high-density areas promote the intensive use of resources,they also tend to lead to a decline in spatial quality.However,existing research largely remains at the level of qualitative descriptions,and there is still a lack of systematic quantitative analysis to reveal the underlying interactive mechanisms.Open space ratio,as a key counter-indicator,can effectively moderate the interrelationships among floor area ratio,building density,and building height.Taking Xicheng District in Beijing as a case study,this research quantitatively reveals the clustering characteristics of high-density spaces through the global Moran's I index,correlation analysis,and the entropy weighting method.The result found that:In terms of spatial distribution,floor area ratio,building density,and building height all exhibit significant spatial clustering(global Moran's I ranging from 0.27 to 0.43),whereas the open space ratio exhibits a random distribution(global Moran's I=0.013,p>0.1),indicating greater flexibility in planning controls.Regarding indicator correlations,the open space ratio exhibits a very strong negative correlation with floor area ratio and building density,with Spearman's correlation coefficients of-0.975 and-0.752,respectively,quantitatively revealing the inverse relationship between development intensity and open space.The results of the spatial intensity model reveal the hierarchical relationships among the indicators:building height(0.40)and floor area ratio(0.36)are the dominant factors determining spatial utilization efficiency;in contrast,the weight of the open space ratio(0.05)ranks last,with an influence only one-eighth that of building height,indicating that vertical development intensity has a far greater impact on current intensity levels than spatial openness.This provides data-driven decision support for accurately identifying potential renewal areas characterized by"high density and low intensification,"thereby facilitating the refined renewal of high-density districts during the existing stock phase.关键词
