Evolution of urban construction land structure in Henan Province based on information entropy and equilibrium model

Abstract

The paper aims to accurately identify the evolution characteristics of urban land use structure in Henan Province, clarify the current situation and problems of urban land use structure, and provide reference and basis for the optimization of urban land use structure and urban land allocation. Statistical analysis, comparative analysis, information entropy, equilibrium and dominance were used. From 2007 to 2016, the urban construction land area in Henan Province showed an overall upward trend; from 2007 to 2016, the per capita construction land area in Henan Province showed an overall upward - downward - upward trend. From 2007 to 2016, the information entropy, equilibrium and dominance curves of urban land use structure in Henan Province are in a stable state, which shows that the change of urban land use structure tends to be gentle, the overall fluctuation range is not large, and all types of land are relatively uniform. To a certain extent, it can show that urban land development in Henan Province is relatively mature. In the structure of urban construction land in Henan Province, the proportion of residential land is the highest, and its area and proportion are increasing year by year. This is closely related to the increase of urban population. The proportion of industrial land is higher, but it decreases year by year. The land for urban green space, square and road traffic facilities is increasing year by year, and others. Although the land use area of different types is increasing year by year, the proportion of structure is decreasing year by year, and the urban land use structure of Henan Province is in the stage of continuous adjustment.
