龙岩市城市生态安全评价研究

Ecological security assessment of Longyan City

以福建省龙岩市为研究对象,参考国内外有关城市生态安全评价方面的研究成果,以龙岩市2004—2013年的调查资料和统计数据为基础,运用熵值法和层次分析法求各指标综合权重,对城市进行生态安全模糊物元评价.结果表明:龙岩市城市生态系统欧氏贴近度呈现上升趋势,由不安全状态转变为较安全状态,但仍存在恶化的可能.这也反映了龙岩市经济、环境、社会子系统三者间未能做到协调发展.说明龙岩市人与环境的矛盾依然存在,城市生态安全投入仍需进一步加强.

The focus of this article is the urban ecosystem in Longyan,a city located in Fujian Province.After studying various research papers in this field all over the world,a system was created using both the Analytic Hierarchy Process and the Entropy Method on research data to find the index weight.The fuzzy matter-element model evaluation method was applied to the 2004--2013 official survey and statistic data in Longyan,measure the ecology security of Urban Ecosystem.The result showed that the Euclid approach degree of Longyan ecosystem rises consistently during the research period,from insecure state to relatively secure.However,there is still the possibility of deterioration.It also reflects the three core subsystems：economy,environment and society,are not developed well coordinately and the contradiction between human and nature still exist in the city.Therefore,the city government needs to take actions to further improve the local urban ecosystem.
