浙江省城市化与生态环境协调度及其胁迫关系探讨

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.

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

The coordination degree and interactive coercing model together with AVDM and SEM were used to determine the index weight and an eco-environment and urbanization evaluation system was built.The interactive coercing relationship and coordination type of Zhejiang Province in 2000-2014 were studied.There exist interactive coercing relationship between eco-environment and urbanization in Zhejiang Province, the evolution path follows the bi-exponential function;the former has significant constraint on the latter, the latter causes obvious coercing 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 response.Comprehensive coupling coordination types of Zhejiang Province in 2000-2014 could be divided into 4 stages, which are running coordination phase (2000-2003), basic coordination phase (2003-2005), antagonistic coordination phase (2005-2010) and good coordination phase (2010-2014).
