摘要
在分析城市河流生态系统健康概念和内涵的基础上,借鉴前人研究成果,以水量、水质、河岸带、物理结构和水生生物建立评价指标体系,运用层次分析法求得各评价指标权重,采用模糊数学构建评价模型,对六盘水市水城河生态系统健康进行评价,结果表明,水城河生态系统健康处于不健康等级,最大隶属度值为0.259 5,为六盘水市水城河的规划和治理提供了科学参考。
Based on the analysis of the concept and connotation of ecosystem health of urban river, referencing to previous research results, the evaluation index system is established with the water quantity, water quality, riparian zone, physical structure and the a- quatic organisms. The analytic hierarchy process （APH） is used to calculate the weight of each evaluation index weight and the fuzzy mathematical is used to establish the evaluation model to evaluate the ecosystem health of Shuicheng River in Liupanshui city. The results show that the ecosystem health of Shuicheng River is at unhealthy level, the maximum membership degree value is 0. 259 5. This provides scientific reference for the planning and management of the Shuicheng river in Liupanshui city.
