| 摘 要： | 考虑反映城市河流生态系统的水量、水质、河岸带、水生生物与物理结构等5个方面,构建了城市河流生态系统健康评价指标体系.城市河流生态系统健康评价模型采用模糊模式识别模型,各指标权重利用层次分析法确定.根据评价指标的选择原则,选取8个评价指标,提出5级评价标准,对浑河沈阳段2009年的河流生态系统健康状况进行评价,结果表明:浑河沈阳段处于不健康状态.评价结果与实际情况进行对比,证明评价结果是正确的.水资源过度开发利用和污水排放是河流健康状况不良的主要原因.

| Abstract: | This paper establishes a health assessment index system of urban river ecosystem by considering water quantity and quality,riparian,aquatic biological and river physical structure reflecting the urban river ecosystem.The fuzzy pattern recognition model is applied to the urban river ecosystem health assessment and AHP is used to determine the index weights.Based on the choice principle of assessment index,this paper chooses eight assessment indexes and advances five grade assessment standards.The ecosystem h... |
