梅州市城市生态安全评价研究

STUDY ON URBAN ECOLOGICAL SECURITY ASSESSMENT OF MEIZHOU CITY

运用"压力-状态-响应"概念模型构建了城市生态安全评价体系,以层次分析法,确定各指标的权重,构建了数学模型,对2003—2010年梅州生态安全水平进行了评价.结果表明:梅州市在2003—2010年生态安全水平整体呈上升趋势.2003—2008年安全等级为Ⅲ,处于临界安全状态.2009、2010年安全等级为Ⅱ,处于较安全状态.

Ecological security assessment index system was established by employing pressure-state-response（P-S-R） concept model and constructed mathematical model by means of Analytic Hierarchy Process（AHP）.Level of eco-security from 2003 to 2010 was evaluated,which indicated an upward trend in general： the eco-security rating from 2003 to 2008 was III,which means that it was in a warning state,and the eco-security rating in 2009、2010 was II,in a quite secure state.
