Abstract:This paper selects 16 representative indicators from the economic, social, and ecological environment (environmental level, protection, and pressure) of ecological construction. Based on multi-indicator panel data, the method of combining entropy weight method and functional analysis is applied to the Yangtze River. The ecological construction of the economic belt from 2006 to 2017 was dynamically evaluated, and the trend of ecological construction in each region was analyzed in depth. From this, the application value of functional comprehensive evaluation in ecological construction is explored, which provides a theoretical basis for ecological construction work in the Yangtze River Economic Belt and enables it to take effective measures. It is concluded that the ecological construction of the Yangtze River Economic Belt has a rising trend during 2006-2017; the level of ecological environment: the U-shaped distribution in the eastern region and the rising trend in the central and western regions; ecological protection and pressure: the eastern, central, and western regions are constantly rising and changing The trends are similar; economic and social factors have the greatest impact on ecological construction, followed by environmental pollution and environmental governance; the development status of ecological construction and economic construction have certain characteristics of convergence, and there are obvious aggregation phenomena; for the development status of ecological construction in the past two years , 11 regions have similar upward trends. In general, the functional comprehensive evaluation model is effective and reasonable for analyzing the dynamic ecological construction of the Yangtze River Economic Belt.
