摘要
针对地铁施工对城市生态环境影响日益严重这一现状,建立了地铁施工诱发城市生态环境安全的"社会—经济—自然"复合生态安全评价指标体系;结合系统动力学方法构建地铁施工情境下城市生态系统安全的动力学模型;提出基于云模型的模糊数据挖掘方法,通过单指标相对隶属度计算进行预警分析,结合多属性决策,得到综合指标的预警区间变化趋势图;并以武汉市地铁施工项目为实际背景,实现对武汉市地铁施工诱发城市生态安全系统动态预警的时空演化分析,得到武汉市地铁施工诱发城市生态安全系统目前处于较差状态,需要重点加强改进的结论。
For the urban ecological environment induced by subway construction is worsening,the paper established a complex evaluation index system based on ＂social-economic-natural ＂complex ecosystem,built the dynamics model of urban ecosystem induced by subway construction based on system dynamics,and proposed the fuzzy data mining method based on cloud model. The method realized that warning analysis of single index by calculating the relative membership degree,combined with multi-attribute decision-making, and gave the change chart of warning internal of the comprehensive index. At last,Wuhan Metro construction was set as an example to achieve the dynamic warning and space-time evolution analysis of subway construction-induced urban ecological environment security system in Wuhan,the condition of which is finally proved to be the poor state and needs to be improved.
