The evolution characteristics and optimization path of the production-living-ecological functions in Zhengzhou metropolitan area from 1980 to 2020
The study focused on the evolution characteristics of the production-living-ecological functions in Zhengzhou metropolitan area from 1980 to 2020,based on the land use classification data,the GIS spatial exploratory analysis method was used to measure the production-living-ecological functions characteristics of Zhengzhou metropolitan area,and the optimization regulation strategy was put forward.The results showed that,the production and ecological functions of Zhengzhou metropolitan area continued to decline,while the living functions centered on the main urban area of Zhengzhou expanded rapidly;the production functions of the metropolitan area continued to move eastward,the living functions continued to gather around the built-up areas of various cities,and the ecologi-cal functions were concentrated in the western mountainous areas and along the Yellow River,showing a trend of dispersion and frag-mentation;the areas with high comprehensive level of production-living-ecological functions in Zhengzhou metropolitan area were mostly located in the areas surrounded by Xingyang,Xinzheng and Zhongmou,and continued to gather to the core area,and the indi-cators showed an upward trend.Following the principles of increasing the proportion of compound functional land,appropriately ex-panding the land for living functions,intensively utilizing the land for production functions,strengthening the integration function of industry and city,and scientifically distributing the proportion of the number of production-living-ecological functions,this paper put forward the balanced layout strategy of production-living-ecological functions in spatial distribution,in order to promote the sustain-able utilization of land space in Zhengzhou metropolitan area.
