| 中文摘要 |
| 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度的同质性和异质性;并以珠江三角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。 |
| 英文摘要 |
| The principles and specific indicators for urban ecologcal suitability were described. Based on the natures of urban ecosystems,the factors composition analysis and fuzzy maximum tree method were suggested to estimate the homogeneity and heterogeneity of the ecological suitabilities among cities within a region. By exemplifying the group of cities in the Pearl River Delta,the scores of compositional factors and the fuzzy sub-tree sets for the ecological suitabilities of cities were calculated. The results show that the method gave reasonable conclusions and was more practical. |
