生态脆弱民族地区经济发展与生态环境耦合协调评价——以西藏为例

Evaluation on the Coupling Coordination of Economic Development and Ecological Environment in Ecologically Fragile Ethnic Areas——Taking Tibet as an Example

利用熵值赋权法和耦合协调度模型,对2006-2018年西藏经济发展与生态环境耦合协调度进行测度。结果表明:(1)西藏经济发展水平持续快速提升,生态环境水平在波动中缓慢上升;(2)西藏经济发展—生态环境经历了从"经济发展滞后"向"生态环境滞后"的转变;(3)西藏经济发展与生态环境耦合度波动范围为0.44-0.50,耦合关系处于拮抗状态;(4)西藏经济发展与生态环境耦合协调度日益提升,呈现从"轻微失调"向"濒临失调"再向"勉强协调"转变的趋势。未来,应树立和践行协调发展理念,加强生态环境综合治理,提升生态环境水平,转变经济发展方式,降低经济发展对生态环境的胁迫水平。

Taking Tibet as the research area,this paper measures the coupling coordination degree of Tibet’s economic development and ecological environment from2006 to 2018 by using the entropy weighting method and the coupling coordination degree model.The results show that:(1)Tibet’s economic development level continues to rise rapidly,and its ecological environment level rises slowly in the fluctuation;(2)Tibet’s economic development and ecological environment has undergone a change from"backward economic development"to"backward ecological environment";(3)the coupling degree of Tibet’s economic development and ecological environment fluctuates in the range of 0.44 to 0.50,and the coupling relationship is in an antagonistic state;(4)the coupling coordination degree of Tibet’s economic development and ecological environment is increasing,showing a trend of transformation from"slight imbalance"to"near imbalance"and then to"barely coordination".In the future,it should be done to establish and practice the concept of coordinated development,strengthen the comprehensive management of ecological environment,improve the level of ecological environment,transform the mode of economic development,and reduce the stress level of economic development on the ecological environment.
