基于熵权法与协调度模型的宁波市生态文明评价

生态文明评价研究是评估城市或区域生态文明建设进程、诊断生态文明建设问题的重要环节, 是探索科学生态文明实践模式的理论前提. 从经济转型、社会和谐、环境友好、空间优化四方面构建生态文明评价指标体系, 采用熵权法确定指标权重, 并运用协调度模型从时、空双维度实证评价宁波10年来的生态文明水平及其演化. 研究发现: (1)2002~2011年宁波生态文明水平呈上升趋势, 生态文明发展趋向科学化, 但稳定性较差, 尚未形成持久动力; (2) 10年间宁波的社会、环境、空间子系统整体趋好, 但经济子系统协调度较低; (3)2011年宁波各行政单元的生态文明综合协调度呈市区高于外围, 北部高于南部的分布特点; (4)聚类将6个县区归为4类, 即宁海与象山亟待全面提升型、余姚与奉化低水平环境友好型、慈溪高水平环境友好型、市区生态文明高质型.

Ecological Civilization Assessment for Ningbo Based on Entropy-right Method and Coordination Degree Model

Study of ecological civilization assessment is the vital part for evaluating the process of constructing ecological cities or districts and finding problems concerned, and it is also the theoretical exploration in scientific practice. Taking Ningbo as a case study, in this paper an index system of ecological civilization is established from the aspects of economy transformation, society harmony, friendly environment, and spatial optimization. The level of ecological civilization and its evolution are evaluated in temporal and spatial perspective for Ningbo ecological conditions in last ten years by applying Entropy-right Method to define the weight of each indicator and Coordination Degree Model. The results are summed up as follows：（1） From 2003 to 2011, the ecological civilization level of Ningbo is on the rise and shows a scientific development trend but with poor stability and shortage of the sustaining momentum;（2） During the ten-year period, the subsystems of society, environment, space of Ningbo demonstrate an overall good trend but with lower coordination degree of economy; （3）The distribution of the comprehensive coordination degree of ecological civilization for each administrative unit in Ningbo can be characterized as：In 2011, the level in urban area is higher than that in peripheral areas, and level in the north is higher than that in the south;（4） Based on the clustering method, the lever is classified into 4 types for 6 sampled counties （cities）, which is specified as： Further-overall-promotion type： Ninghai county and Xiangshan county;Low-friendly-environment type：Yuyao county and Fenghua county;High-friendly-environ-ment type：Cixi county;High ecological quality type：Ningbo city.
