多维测度下沈阳市城市开发强度空间特征研究

Research on Spatial Characteristics of Urban Development Intensity in Shenyang City under Multi-Dimensional Measurement

城市开发强度是城市开发利用累积程度及承载密度的综合反映,选取土地开发、建筑建设、功能集聚、人口承载4个维度表征城市开发强度,对沈阳市城市开发强度进行小尺度测度并揭示其空间特征。结果表明:多维测度下沈阳市城市开发强度呈单核心与多中心分布相结合的空间特征;各维度开发强度耦合协调性空间差异明显,在中心城区及周边新城中心呈圈层式结构;各维度测度下开发强度呈现较为显著的空间异质性和空间集聚状态。

Urban development intensity comprehensively reflects the degree of accumulation and bearing density of urban development and utilization,selects the four dimensions of land-building,function and population to characterize the intensity of urban development,and measures the intensity of urban development in Shenyang at a small scale and reveals its spatial characteristics.The results show that the urban development intensity of Shenyang city shows the spatial characteristics of combining single-core and multi-center distribution under multi-dimensional measurement,the spatial difference of coupling and coordination of development intensity in various dimensions is obvious,and the circle structure is in the center of the central urban area and the surrounding new city center,and the development intensity shows significant spatial heterogeneity and spatial agglomeration under the measurement of various dimensions.
