| 摘 要： | 城市环境质量综合评价中,影响环境的因素很多。这众多的因素在不同的层次中对城市环境起综合的影响作用,它们往往带有“模糊性”。采用一般数学方法难于揭示其客观的结论,更难于在不同城市或区域之间进行有效的比较。本文采用模糊数学对其诸因素进行多层次综合评判,用其各个等段上的隶属度反映城市环境质量的综合定性结论,并与等级模糊映射值的转置矩阵进行运算,得出各个城市或城区环境质量综合评价值,用综合评价值相比较有效地反映出各城市环境质量优劣水平。

| Abstract: | In the synthesis assessment of urban environmental qualities, there are a lot of factorsimpacting urban enviromental qualities. Each of them might play the defferent roles in thedefferent layers. Generally, the relationship among them always is fuzzy. It is difficultto get a absolute result using general mathematics and even more difficult to comparethe environmental qualities among several cities. In this paper, the mathematical model for multilayer fuzzy comprehensive judgeme-nts is applied to the synthesis assessment of urban environmental qualitie sin several layers.The result reflects the environmental qualities of defferent urbans in the subordinate level. |
