摘要: 为合理评估石葵河流域健康现状,构建了由河岸特征、河岸植被、河流水文特征、流域形态特征和社会经济5个标准层及19个评价指标组成的河流健康评价体系,并在此基础上构建各个指标所对应的评价标准。通过层次分析法对各个指标的权重进行计算,依据构建合理的评价模型对其综合评价。结果显示:石葵河流域健康综合评价指数EI为3.75,处于基本健康状态。分析存在的主要问题,并提出河流改善的建议,为石葵河的河流规划、管理和水资源合理开发利用提供了参考。Abstract: A river health assessment system consisting of river bank characteristics,river bank vegetation,river hydrological characteristics,watershed morphological characteristics,social and economical and evaluation indicators was constructed to reasonably evaluate health status of the Shikui River Basin.The weight of each index was calculated by using analytic hierarchy process to build a reasonable evaluation model and comprehensive evaluation.Results showed that the EI of Shikui River Basin was 3.75 in the basic state of health.Main problems and suggestions were put forward,which provided some reference for river planning,management and rational development and utilization of water resources of Shikui River.
