基于PSR-AHP方法的中山市生态安全评价

ECOLOGICAL SECURITY ASSESSMENT OF ZHONGSHAN CITY BASED ON THE "PRESSURE-STATUS-RESPONSE"-ANALYTIC HIERARCHY METHOD

  • 摘要: 运用P-S-R概念模型,构建中山市生态安全评价指标体系.采用层次分析法,确定各指标因子的权重.通过数学模型计算出各指标的安全值.结果显示,2006年中山市生态环境压力、生态环境状态、人文响应子系统的安全值分别为0.1601、0.2677、0.2736.中山市生态安全综合值为0.7014,属于较安全级别.表明中山市的生态环境系统在人文响应子系统的良好控制下状态较好,生态环境系统承受的压力较小,人口-资源-环境-经济复合系统处于相对协调的状态.但该值也濒临临界安全值等级,有必要进一步加强环境综合整治、优化景观生态格局.

     

    Abstract: An ecological security assessment index system of Zhongshan city was constructed based on the Pressure-status-response conceptual model. The weight of each index was determined by the Analytic Hierarchy method, and the values of ecological security assessment index were calculated. The results showed that the safety values of ecological environment pressure, ecological environment status and humanity response subsystem are 0.1601, 0.2677 and 0.2736, respectively. The comprehensive value of ecological security is 0.7014. The level of ecological security of Zhongshan city is relatively safe. It is concluded that, under the control of humanistic response subsystem, the status of ecological environment is good. The pressure of ecological environment is relatively small. The status of population-resource-environment-economic compound system is relatively harmonious. But the comprehensive value of Zhongshan city is close to critical safety value. It is necessary to optimize ecological environment and improve landscape ecological pattern.
