Research on the Impact of Urban Land Use Structure Based on Big Data on Space Performance in Kunming

Abstract

Based on the big data of urban land use, this paper calculates and analyzes the changes in Kunming's urban land use structure in 2003, 2008 and 2014 respectively, constructs the index system of Kunming's urban space performance, and performs the linear regression analysis on the information entropy and performance value of the land use structure by SPSS software based on the space performance value calculated by comprehensive evaluation model after calculation of the weight of each index by AHP decision analysis method . The results show that Kunming's urban land use structure was constantly improving and tending to be balanced during the study period. With the change of urban land use structure, the value of urban space performance also increased accordingly, indicating that the information entropy of urban land structure has a certain pulling effect on space performance.
