宁夏回族自治区生态环境与经济发展耦合协调研究

为了研究区域生态环境与社会经济协调发展状况,以宁夏回族自治区为例,通过构建评价指标体系,综合运用熵权法、耦合协调度模型、剪刀差方法以及耦合度模型对宁夏生态环境与社会经济发展状况、耦合协调水平以及耦合度演化趋势进行了综合分析。结果显示:研究期间宁夏生态环境系统综合发展指数呈波动上升的变化趋势,社会经济发展水平逐年上升;耦合协调指数由0.3225上升至0.5962,说明区域生态环境与社会经济的关系不断缓和,趋向于协调发展;剪刀差呈先减后增的“U”型变化趋势,说明两系统发展差异呈先减小后增大的变化态势;宁夏生态环境与社会经济发展耦合度介于(45°,90°],说明两系统处于协调发展阶段,而耦合度整体呈上升态势,说明经济发展与生态环境之间的矛盾开始显现。基于耦合模型所建立的耦合协调度,较好地反映了宁夏生态环境与社会经济之间交互胁迫的耦合发展过程,对于正确认识宁夏生态与经济系统耦合发展规律,促进宁夏生态与经济协调发展具有重大意义。

Research on the Coordinated Development of Ecology and Economic System of Ningxia Hui Autonomous Region

In order to study the coordinated development of regional ecological environment and social economy,Ningxia Hui Autonomous Region was taken as an example,and based on the data of social economy and ecological environment,the evaluation index system was constructed,and the comprehensive analysis on the ecological environment and social economy development status,coupling coordination level and coupling evolution trend of Ningxia was made by using entropy weight method,coupling coordination degree model,scissors difference method and coupling degree model.The results show that during the study period,the comprehensive development index of Ningxia′s eco-environment system presented the fluctuating and rising trend,and the level of social and economic development had been rising year by year;the coupling and coordination index rose from 0.3225 to 0.5962,indicating that the relationship between regional eco-environment and social economy was becoming more and more relaxed,and tended to develop harmoniously;the scissors gap showed the U-shaped change trend,indicating that the development of the two systems was poor in Ningxia,the coupling degree of ecological environment and social economic development was between(45°,90°],indicating that the two systems were in the stage of coordinated development,while the coupling degree was rising as a whole,indicating that the contradiction between economic development and ecological environment began to appear.The coupling scheduling based on the coupling model reflected the coupling development process of the interaction between the ecological environment and social economy in Ningxia,which was of great significance to correctly understand the coupling development pattern of the ecological and economic system and promote the coordinated development of the ecological and economic system in Ningxia.
