艾比湖流域城镇化与水土资源效益测评及协调性分析

为推动艾比湖流域城镇与水土资源开发的协调发展并深化研究,以艾比湖流域各县市为研究对象,构建城镇化与水土资源效益评价指标体系,运用熵值法和主成分分析法计算并评价2005、2010和2015年3个时间点的城镇化水平、土地资源效益和水资源效益;利用耦合协调度模型分析三者的耦合状况及协调发展状态.结果表明:2005-2015年艾比湖流域城镇化水平与水土资源效益整体不高,水资源效益发展速度明显低于其他二者的发展速度,其中独山子区发展最好,温泉县较低;各县市的城镇化水平和水土资源效益的耦合度和协调发展度类型差异较大,各城镇的耦合度类型从主要集中在拮抗阶段到磨合阶段,协调发展度类型由勉强失调转变为初级协调.

Evaluation and coordination analysis of urbanization and land and water resources efficiency in Ebinur Lake Basin

In order to promote and deepen the coordinated development of urbanization,water and land resources in Ebinur Lake Basin,counties and cities of which were taken as the study area.With evaluation index system constructed,by means of entropy method and principal component analysis,this paper calculated and evaluated the urbanization level,water and land resources efficiency in year 2005,2010 and 2015,respectively.Coupled degree model was applied to analyze the coupled coordination development.The results showed that from 2005 to 2015,the urbanization level,water and land resources efficiency of Ebinur Lake Basin were not high and the development speed of water resources efficiency was obviously lower than the others.Among all counties and cities,the efficiency development of Dushanzi district was the best and that of Wenquan country was the lowest.With the coupled coordination development degree of counties and cities varied greatly,the coupled types concentrated from the antagonistic stage to the grinding stage,and the coordination development types were turned from uncoodination into primary coordination.
