浙江省城市化与生态环境协调度及其胁迫关系探讨

Study on the Relationship between Urbanization and Ecological Environment Coordination and Stress in Zhejiang Province

运用交互胁迫、耦合协调模型,结合主观均方差分析法和客观结构熵值法确定指标权重,通过建立指标体系研究2000—2014年浙江省生态环境和城市化的交互胁迫关系和协调类型。结果表明:浙江省生态环境和城市化之间存在交互胁迫关系,演变状态符合双指数函数;前者对后者有显著的约束作用,后者对前者有显著的胁迫作用。对城市化综合水平影响程度大小依次为经济、社会与人口城市化,对生态环境综合水平影响程度大小依次为生态环境压力、状态与响应。2000—2014年浙江省综合协调耦合类型分为磨合协调阶段(2000—2003年)、基本协调阶段(2003—2005年)、拮抗协调阶段(2005—2010年)和良好协调阶段(2010—2014)4个阶段。

The coordination degree and interactive coercing model together with AVDM and SEM were used to determine the index weight and an eeo-environment and urbanization evaluation system was built. The interactive coercing relationship and coordination type of Zhejiang Province in 2000--2014 were studied. There exist interac- tive coercing relationship between eco-environment and urbanization in Zhejiang Province, the evolution path fol- lows the bi-exponential function; the former has significant constraint on the latter, the latter causes obvious coer- cing on the former. The influence degree of the comprehensive level of urbanization follows as economy, society and population urbanization; and for ecological environment is the ecological environment pressure, the state and the re- sponse. Comprehensive coupling coordination types of Zhejiang Province in 2000--2014 could be divided into 4 sta- ges, which are running coordination phase （2000--2003）, basic coordination phase （2003--2005）, antagonistic coordination phase （2005--2010） and good coordination phase （ 2010--2014）.
