| In 2014,our country proposed building the "Yangtze River Economic Zone"regional development strategy,and promulgated the " relying on the golden waterway to promote the development of the Yangtze River Economic Zone," a clear positioning of the Yangtze River economic zone is ecological civilization Demonstration zone.In 2016,the "Yangtze River Economic Development Plan"launched,further clarified the Yangtze River economic development of the basic idea is the ecological priority,green development.Water ecological civilization construction is the core content of ecological civilization construction,and studying the Yangtze River economic water ecological civilization construction has important practical significance.The construction of water ecological civilization is based on the concept of water and harmony,and the natural law of water ecological environment as the criterion.It aims to realize the sustainable development of water ecology-economy-social system,including water resources civilization,water security civilization,Water environment civilization,water management civilization and water culture civilization.Based on the practice of water ecological civilization evaluation index published by existing ministries and commissions and provincial cities,this paper constructs a set of evaluation index system framework based on the connotation of water ecological civilization,and adopts the principal component analysis method to analyze the Yangtze River economic zone 2006-2015 the status of water ecological civilization.First,the paper analyzes the correlation between the index of eco-civilization construction and the mean value of five-dimension index system.It is found that there is a positive correlation between the comprehensive index of water ecological civilization construction and the indicators of water resources civilization and water management civilization index system in the Yangtze River.Secondly,the comprehensive index of water ecological civilization construction and five dimension indicators in recent ten years.Finally,the civilization level is divided into five categories:complete civilization,more civilized,general civilization,less uncivilized,completely uncivilized,so as to explore the present situation of water ecological civilization construction in three regions.In general,the level of ecological civilization construction in the Yangtze River economic zone has been increasing in the past ten years,but the imbalance between the provinces and the provinces is obvious,and the level of the eastern provinces is better than that of the central and western regions.The western provinces are better than the central area.On the dimension of civilization,the Yangtze River economic belt provinces and cities of the sub-dimension of civilization construction focus is different,the East and West three regional development strategies are also different.According to the status quo of the construction of the ecological civilization of the Yangtze River economic belt,on the one hand,the overall design should be done,combining with the five major development concepts,on the other hand to strengthen the five dimensions of civilized construction.Firstly,sharing the water resources of the Yangtze River;secondly,to coordinate the Yangtze River economic zone with water resources allocation;thirdly,to protect the water environment as green ecological corridor;fourth,to innovate the construction of water ecological civilization management system;lastly,open inside and outside with the idea of water ecological civilization. |
