| 摘 要： | 生态安全是区域可持续发展的基础保障，是生态建设的核心内容．闽侯县是福州城市扩展的重点区域，亦是福建省会福州生态安全的关键保障区域．本研究运用PSR（“压力-状态-响应”）框架模型构建区域生态安全评价指标体系，选择多目标决策方法熵权“TOPSIS法”（逼近于理想值的排序方法）评价闽侯县2005-2010年的生态安全动态变化特征．结果显示2005-2010年闽侯县生态安全平均水平处于预警状态，闽侯县亟待改变区域发展模式，增强内涵发展刻不容缓；研究发现生态安全等级水平为生态压力-状态-响应的综合作用，生态系统状态与生态安全水平密切相关，而生态压力和生态响应对生态安全水平起着系统动态调节作用．

| Abstract: | Ecological security is the basic guarantee of regional sustainability and core content of eco-logical construction. As an urban expansion area of Fuzhou, the coo-security of Minhou County is closely related to that of the whole city area. This paper uses PSR （pressure-state-response） model to build up an indicator system for the evaluation of regional eco-security, and applies TOPSIS （Tech-nique for Order Preference by Similarity to Ideal Solution） method to integrate the multi-indicators into a comprehensive index according to entropy values for assessing dynamic eco-seeurity of Minhou from 2005 to 2010. Results show that the average level of Minhou eeo-seeurity during the study period is close to a warning level, meaning that it is now an urgent moment to change the developing mode of the county. It is found that the eeo-seeurity level can be a comprehensive indicator of ecological pressure-state-response. |
