昆明市城市用地结构对空间绩效的影响研究

The Impact of Urban Land Use Structure on Spatial Performance in Kunming

摘要: 文章基于城市土地利用的结构信息熵和均衡度的原理，对昆明市2003年、2008年和2014年的城市用地结构的变化状况进行计算分析，构建昆明城市空间绩效的指标体系，用AHP决策分析法计算出各项指标权重后根据综合评价模型算出空间绩效值，通过SPSS软件对昆明用地结构信息熵与绩效值进行线性回归分析。结果表明：研究期间内昆明市城市用地结构在不断完善，有向均衡化转变的趋势，随着城市用地结构的改变城市空间绩效值也有相应的提高，说明城市土地结构信息熵对空间绩效有一定的拉动作用。

Abstract: The principle of information entropy and equilibrium degree of the city based on land use in Kunming City, 2003, 2008 and 2014 were analyzed and calculated with the change of city structure, constructing the index system of Kunming city spatial performance, calculating the index weight according to the comprehensive evaluation model to calculate the spatial performance value. AHP decision analyzes the structure and performance of Kunming with information entropy value of linear regression analysis of SPSS software. The results show that the urban land use structure of Kunming is constantly improving and tends to be balanced during the study period. With the change of urban land use structure, the urban spatial performance value has been improved correspondingly, which indicates that the information entropy of urban land structure has a certain pulling effect on the spatial performance.
