基于函数型数据的长江经济带生态建设动态综合评价

Dynamic Comprehensive Evaluation of Ecological Construction of the Yangtze River Economic Belt Based on Functional Data

从生态建设的经济、社会、生态环境3个方面选取16个代表性指标,基于多指标面板数据,运用熵权法与函数型分析相结合方法对长江经济带2006-2017年的生态建设进行动态评价,深入分析各地区生态建设的变化趋势,探讨函数型综合评价在生态建设中的应用价值。得出结论:长江经济带地区在2006-2017年期间生态建设上升趋势明显;生态环境水平:东部地区呈U型分布,中西部地区呈上升趋势;生态保护和压力:东中西不断上升,且变化趋势相似;经济和社会因素对生态建设影响最大,其次为环境污染和环境治理;生态建设的发展状况与经济建设有一定的趋同特征,且具有明显的聚集现象;对于近两年生态建设发展状况,11个地区上升变化趋势相似。总体而言,函数型综合评价模型对长江经济带的动态生态建设情况分析有效且合理。

This paper selects 16 representative indicators from the economic,social,and ecological environment 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 is dynamically evaluated,and the trend of ecological construction in each region is analyzed in depth. From this,the application value of functional comprehensive evaluation in ecological construction is explored. It is concluded that the ecological construction of the Yangtze River Economic Belt has a rising trend during 2006-2017. Ecological environment level:the eastern region is U-shaped,and the central and western regions are on the rise. 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.
