三明市城市生态安全评价研究

Ecological Security Assessment of Sanming Urban Eco-system

城市生态安全随着城市化的进程逐渐引起人们的重视.正确的评价城市的生态安全对于制定相应法规和应对措施有着重要的意义.为此,选择三明市为例,对城市进行生态安全模糊物元评价,评价结果显示:三明市城市生态系统安全水平总体呈现上升趋势,整体上升幅度接近33%,由临界安全逐步转变为较安全.反映出在三明市经济与社会快速发展的同时,市区生态环境问题逐渐浮现,环境保护与经济社会发展尚未协调,人与环境的矛盾依然存在.

As the urbanization accelerates,urban ecological security gradually gains increasingly wider attention.An appropriate evaluation of the city ecological security is of great importance for the making of corresponding regulations and solutions.A case study of Sanming City is made to evaluate its ecological security with fuzzy matter-element evaluation model.The results find a generally rising trend of Sanming＇s urban ecological security,which sees an increase of approximately 33%,rising from criticality safety to relative safety.This also shows that with the rapid development of Sanming＇s economy and society,the urban ecological environment problems pop up,and the coordinated development between the environmental protection and the social and economic development is still far from satisfactory,and the conflicts between people and the environment are still wanting a solution.
