河南省相对资源承载力时空演化特征研究

Study on time-spatial evolution characteristics of relative carrying capacity of resources in Henan province

采用相对资源承载力测度模型,并借助GIS空间表达工具,研究了2000~2013年河南省相对资源承载力的时空演化特征.研究结果表明:(1)河南省人口相对于综合承载力长期处于超载状态,自然与经济两种资源承载力协调性较差,自然资源承载力大于经济资源承载力.(2)各地市间资源承载力差异显著,郑州、黄淮及南阳地区自然资源承载力强;郑州、南阳、洛阳及豫中、黄淮地区人口大市经济资源承载力、综合承载力强;仅有郑州综合承载力长期处于盈余状态,南阳及黄淮4市人口严重超载.

With urbanization being propelled constantly and economic growing rapidly,the contradiction between regional development and resource environment has been growing larger at significant pace,which seriously jeopardizes and dampens regional-social progress.Therefore,it is of great importance to study the carrying capacity of resources for regional development.Using measure model of relative carrying capacity of resources and GIS spatial expression tool,the time-spatial evolution of relative carrying capacity of resources in Henan province in2000-2013is studied.Results show:(1)The population of Henan province is surplus with respect to the comprehensive carrying capacity.The coordination of natural and economic resources is in shortage,and carrying capacity of natural resources is greater than that of economic resources.(2)The difference of carrying capacity of resources between different cities is noteworthy.There are strong carrying capacities of natural resources in Zhengzhou,Huang Huai and Nanyang regions.There is strong carrying capacity of economic resources in Zhengzhou,Nanyang,Luoyang,Xuchang,Zhoukou,etc.Comprehensive carrying capacity of Zhengzhou,Nanyang,Zhoukou,Luoyang,Zhumadian and other cities are relatively stronger.Only the comprehensive carrying capacity of Zhengzhou is in surplus state in the long term,while Nanyang,Huang Huai and other two cities are in serious superfluous state in terms of population load.
