Coupling and Coordination Measurement and Interactive Analysis of ESRE System in CPER
Based on the coupling and coordinative characteristics of economic,society,resource and environment(ESRE)system in Central Plains Economic Region(CPER),taking economic,society,resource and environment as three composite systems respectively,through the quantitative integration measure,the paper aims at probing into the coupling interaction and coordinating relationship of ESRA system of Central China.The results show that the coupling degree of ESRE system is low,and the time sequence of coupling degree in CPER is at resisting stage from 1995 to 2012.The coupling coordination degree of ESRE system rose from 0.351 3 to 0.434 9in 1995 2012,and coordination intensity was in the middle level.The order degree of economic and social system had a more substantial increase with the improvement of new urbanization level,while the order degree of resource and environment system was in a fluctuated status.This shows that the sped up process of economic and social system in CPER in several years has brought more and more pressure to its environment system,so it is necessary to correctly handle and coordinate the relationship between the rapid developing urbanization and the increasingly severe environmental condition in CPER,and the measures should be taken as soon as possible to urge the development direction of the coupling ESRE system coordinately.From the spatial distribution status,the coupling coordination degree is similar to comprehensive coordination index,which presents Northwest Southeast distribution pattern.The spatial distribution pattern of coupling degree is different from coupling coordination degree and comprehensive coordination index,and some individual level was in inverted state.The main influencial factors of coupling coordination degree are still economic and social factors,although the resource and environment factors has some effect on coupling degree but little effect on the overall coupling coordination degree.
