区域城市生态环境适宜度比较方法研究

根据城市生态系统的性质，提出利用同向因子合成分析和模糊最大树方法，量化分析区域内城市之间生态适宜的同质性和异质性；并以珠江三角６洲地区城市群为算例，计算了城市生态环境适宜度的合成因子得分值和模糊子树集。结果表明，利用该方法得出的结论合理，具有较好的适用价值。

Comparative Study on Ecological Suitability of Cities Within a Rain

The principles and specific indicators for urbanecoledcal suitability were described. Based on thenatures Of urban ecosystems, the factors composition analysis and fuzzy maximum tree methodwere suggested to estimate the homogeneity andheterogeneity of the ecological suitabilities amongcities within a region. By exemplifying the groupof cities in the Pearl River Delta, the scores ofcompositional factors and the fuzzy sub--tree setsfor the ecological suitabilities of cities were calculated. The results show that the method gavereasonable conclusions and was more practical.
