摘要
运用模糊数学理论,建立了城市生态系统评估的基本模型,设计了评价城市生态系统的指标集,以上海市近5年的统计数据为依据,计算了相应的评估值,根据该市生态环境的现状以及模型值与传统方法结果的对比,表明本模型的计算较为准确。
A basic evaluative model of urban ecosystem is put forward and the evaluative index set for city ecological system is also designed based on the theory of fuzzy mathematics. According to latest 5 years statistics of Shanghai city, the volue of ecological environmental index are calculated. Evaluative conclusion proved that the model is of higher reliability by comparing the situation of ecological environment of this city and its model value with the traditional method.
