泛长江三角洲地区经济发展与生态环境耦合协调关系分析

以泛长三角地区41个地级市以上的政区为例,运用改进熵值法计算经济发展及生态环境系统的综合得分,并运用耦合协调模型分析1999~2013年两系统的耦合协调度及其演变,最后通过经济发展与生态环境系统得分排名划分4种类型,提出未来泛长江三角洲经济发展分类指导建议。研究结果表明:(1)1999~2013年泛长三角地区经济发展与生态环境的耦合度C∈0.5,0.8],整体位于磨合阶段;而系统协调度D∈0.3,0.5],整体属于中度耦合协调;(2)1999~2013年泛长三角经济发展与生态环境系统耦合协调度呈现上升态势,但经济发展与生态环境系统综合评价值仍表现负相关的特征;(3)未来苏南地区、皖江地区、杭甬地区需要进一步调整产业分布结构,提升城市经济发展环境;而苏北地区、皖西地区、浙西南地区需要进一步增加城市经济发展的软、硬实力各种要素的投入,并将城市生态环境优势转化为经济增长优势。

COUPLING AND COORDINATING BETWEEN ECONOMIC DEVELOPMENT AND ECOLOGICAL ENVIRONMENT IN THE PAN YANGTZE RIVER DELTA

With the rapid development of urbanization and industrialization, urban population growth, economic development, resources energy consumption and urban spatial expansion produce marked impacts on ecological environment; at the same time, the ecological environment through the environment selection, funds fight and policy constraint on urban development; environmental degradation, resource depletion, ecological destruction and a series of problems are increasingly highlighted, environmental problems have been the restricting problem of regional economic development. Exploring the relationship between economic development and ecological environment has been the hot topic, it is the inevitable requirement of urban sustainable development strategy. In this paper we took the Pan Yangtze River Delta as the research object. We used the improved entropy method to calculate the economic development and the comprehensive index of ecological environment system. Then we used the coupling-coordination model to analyze economic development and ecological environment system coupling-coordination and its evolution. Finally through the economic development and ecological environment system score ranking classification quadrant, we proposed some urban economic development suggestions in the Pan Yangtze River Delta. The results showed that: (1)the coupling of economic development and ecological environment was between 0.5 and 0.8 during 1999-2013, on the whole located in the running-in stage; while the coordination degree of economic development and ecological environment was between 0.3 and 0.5, generally presenting a moderate coupled coordination; (2)economic development and ecological environmental system coupling and coordination degree raised in the Pan Yangtze River Delta during 1999-2013, but the economic development and ecological environment comprehensive evaluation index system was negatively correlated; (3)in the future, the south of Jiangsu, Wanjiang belt and Hangzhou-Ningbo region need to adjust the industrial structure, improve the environment of urban economic development; and the north of Jiangsu, the west of Anhui and the southwest of Zhejiang need to strengthen urban economic development inputs such as infrastructure and technology, transfer the ecological environment advantage into urban economic development advantage. Meanwhile, it should be pointed out that, this paper also has certain limitation. In this paper economic development and ecological environment system are divided into different subsystems, using the improved entropy method assignment, it has certain scientific and reference, but there are not comprehensive about indicators, need to deepen analysis indicators selection; in addition, we analyzed the coupling-coordinate pattern evolution of economic development and ecological environment system in the Pan Yangtze river delta from 1999 to 2013, but failed to reveal the influence factor and driving mechanism of the pattern generation and evolution, it is also a focus on strengthening direction in this paper.
