摘要
为了对河南省经济发展与水土资源承载力的耦合关系及时空分异进行分析,采用信息熵权法,压力—状态—相应框架和耦合协调度模型等方法对河南省18个地市1999—2013年的水土资源和经济发展状况进行了量化研究。结果表明:(1)河南省经济发展速度高于水土资源承载阈值的增长,水土资源与经济发展缺乏同步性;(2)河南省水土资源与经济发展的耦合协调程度总体为良好协调类型;水土资源与经济发展对比关系主要为水土资源略微滞后型;(3)河南省水土资源与经济发展耦合协调度的空间分布特征为豫东、豫南协调水平最高,豫北次之、豫西最低。该研究不仅能够揭示二者的动态关系,减小水土资源对经济增长的阻尼效应,还能为河南省经济、社会与环境可持续发展提供理论和技术支撑。
In order to analyze coupling characteristics and spatiotemporal variation between economic development and the bearing of water-land resource in He′nan Province,entropy weight and coupling coordination degree model was used in quantitative research on water-land resources,Pressure—State—Response framework and economic development of 18 cities in He′nan Province from 1999 to 2013.The results showed that the speed of economic development in He′nan Province had exceeded the growth of water-land resource,which indicated that the variation between water-land resource and economic development were not synchronized;in general,coupling coordination degree of He′nan Province was at a good level,the correlation between water-land resource and economic development was a slight lag of water and land resources;the spatial distribution of coupling coordination level between water-land resource and economic development was that east and south He′nan covered the highest,followed by north He′nan,and west He′nan was the lowest one.The research results can not only reveal the dynamic relationship between the two,reduce damping effect of water-land resources for the economic growth,but also provide theoretical and technical support for economic,social and environmental sustainable development in He′nan Province.
