摘  要：
基于2010年淮河流域35个地级市城市化和生态环境指标数据,运用模糊物元分析模型建立城市化-生态环境系统指标体系,采用熵值法确定指标权重,构造改进的城市化与生态环境耦合协调度函数,测度淮河流域城市化与生态环境系统交互耦合的协调程度.结果表明:2010年,淮河流域城市化子系统的发展水平低于生态环境子系统,两者综合协调指数值为0.186,两类响应指标之间存在一定差距.城市化与生态环境耦合度的平均值为0.475,流域城市化-生态环境系统处于颉颃阶段.不同城市的城市化发展子系统之间存在较大差异,而生态环境子系统现状发展水平之间差异相对较小.城市化与生态环境协调度的平均值为0.706,表明淮河流域正处于高度协调耦合阶段,城市化与生态环境建设的整体"功效"与"协同"效应较高.

摘  要：
Based on the statistical data of urbanization and eco-environment of 35 cities in the Huaihe River Basin of China in 2010,an index system of urbanization-eco-environment system was established by using fuzzy matter element theory,and the weight of each indicator was calculated by entropy method.The improved function of the coupling coordination degree of urbanization and ecoenvironment was constructed to measure this coupling coordination degree in the Huaihe River Basin.In 2010,the development level of urbanization subsystem in the Basin was lower than that of the eco-environment subsystem,and the integrated coordination index of urbanization and eco-environment was 0.186,indicating that there was a gap between the two types of indicators.The average coupling degree of urbanization and eco-environment was 0.475,indicating that the urbanization -eco-environment system was at antagonistic stage.There was a greater difference in the development level of urbanization subsystem,but a smaller difference in the development level of eco-environment subsystem among the cities.The average value of the coordination degree of all the cities was 0.706,indicating that the Huaihe River Basin was at high coordination coupling stage,and the integrated coherence and synergistic effect of urbanization and eco-environment construction in the Huaihe River Basin was higher.
