海峡西岸经济区生态系统健康评价

基于活力、组织结构、恢复力、生态功能、人类健康等区域生态系统健康标准,综合考虑人为压力、响应措施等因素,构建了海峡西岸经济区(海西区)生态系统健康评价指标体系；针对区域生态系统健康的自然特性与人工特性,采用均方差法和层次分析法,确定了各指标权重；运用模糊综合评价法,建立了海西区生态系统健康评价模型.结果表明:2008年,海西区生态系统健康状态优越,人为压力较轻,区域生态系统健康状况总体较好,但具有显著的空间差异；受固定资产投资、教育经费支出等响应指标的制约,部分地市生态系统健康状况劣于其健康状态.与1992年相比,2000和2008年海西区生态系统健康状况相对较优,驱动要素以经济活力、组织结构、人类健康、人口压力和投资调整等为主；但受建设用地扩张及其引起的自然景观减少、人类干扰增强等制约,2008年海西区生态系统健康状况劣于2000年.

Ecosystem health assessment of economic zone on the west side of Taiwan Strait, China

Based on the standards of regional ecosystem health,including vigor,organizational structure,resilience,ecological function,and public health,and in considering of anthropogenic pressure and response countermeasures,an index system for the ecosystem health assessment of the economic zone on the west side of the Taiwan Strait(Haixi Zone) was built,and,aiming at the characteristics of nature and humanity of regional ecosystem health,the weights of the indices were given by analytic hierarchy process and mean ...
