Study On Land Carrying Capacity Of Golden Triangle Area In Shanxi,Shannxi And Henan Province

As an important natural and social resource,land resource plays an important role in the social and economic development of the region.With the changes of the times,the demand for land is increasing day by day.However,due to the limited amount and scarcity of land resources,it is impossible for land resources to grow according to people's wishes.Therefore,it is of great significance for the local social and economic development to study the local land resources and evaluate their land carrying capacity so as to plan the local land use.This paper takes the "Golden Triangle Area in Shanxi,Shannxi and Henan Province" as the research object,and uses the land use data,socioeconomic indicators,agricultural production data,etc.of 4 cities and 47 counties in the region in 2018,and uses arc GIS and other means to comprehensively The index method and the ecological footprint method evaluate the construction land carrying capacity and cultivated land carrying capacity of 47 counties,respectively.Finally,the classification and analysis of the land carrying capacity of the study area were made by constructing a classification standard.The analysis results are as follows:Bearing capacity of construction land.Among the 47 counties,7 counties show high bearing capacity.From an administrative perspective,these countiesare mainly concentrated in Linfen City,and from a terrain perspective,they are mainly Mountainous areas have higher carrying capacity due to their small population and underdeveloped economy.Twenty-two counties show low carrying capacity.These areas have relatively developed economies and are basically located in the plains.They are densely populated,which makes the contradiction between people and land larger and the carrying capacity lower.Cultivated land carrying capacity.The research results of cultivated land carrying capacity are consistent with the carrying capacity of construction land.A total of 7counties showed ecological surplus of cultivated land,and they were basically mountain counties.Twenty-two counties show ecological deficits,mainly in the plains,and have relatively developed economies.Comprehensive land resource carrying capacity.Through the construction of hierarchical index labeling,comprehensive analysis of the construction land carrying capacity and cultivated land carrying capacity is carried out to obtain the comprehensive land carrying capacity within the region.A total of 39 counties are overloaded,6 counties are loadable,and 2 counties are critical.Among them,Weinan City and Yuncheng City are all overloaded.Sanmenxia City is overloaded except Lushi County.Linfen City is special.Five countiesare loadable.Two counties are overloaded.Is overloaded,and the rest is overloaded.From the perspective of terrain and economy,all the counties in the loadable state are located in mountainous regions and the economy is relatively backward;while the countiesin the overloaded state are basically plain areas,densely populated and economically developed.Through comprehensive research and analysis,the phenomenon of land overload has become more common,and the phenomenon of land overload in economically developed areas is more common.In the future development,these areas should be optimized and developed to promote sustainable local economic development.
