Research on the characteristics of the production-living-ecological land use transformation map in the Zhengzhou metropolitan area
Based on the land use data of Zhengzhou metropolitan area from 1980 to 2020 and constructing the classification system of production-living-ecological land,this paper used the method of geoscience information atlas to explore the characteristics of space-time transfer atlas and fluctuation potential atlas of production-living-ecological land in four time series units from 1980 to 1990,1990 to 2000,2000 to 2010 and 2010 to 2020,and analyzed the transformation law and development process of production-living-ecological land in Zhengzhou metropolitan area in the past 40 years.The results showed that:(1)The structure of production-living-ecological land in Zhengzhou metropolitan area was dominated by agricultural production land and rural living land.The agricultural production land continued to decrease,and the industrial and mining production land,urban living land and rural living land continued to grow.(2)The ecological land such as water area and forest land continued to transfer to agricultural production land,mainly distributed in the plain and along the Yellow River.The transformation of agricultural production land into urban and rural living land and industrial and mining production land was relatively significant,which was mainly distributed in the outer suburbs of the main urban area of Zhengzhou and the periphery of built-up areas such as local cities and counties.(3)In the rising trend map,the area of new agricultural production land was mainly before 2000,and the areas of new urban and rural living land and industrial and mining production land were mainly after 2000.In the falling trend map,agricultural production land became the source of other land changes,and the shrinkage continued to be serious.These achievements can provide technical support for the intensive use of land space and land management and early warning in Zhengzhou metropolitan area.
