摘要
从白河和潮河的河流水文、水质状况、河流地貌、生物状况以及社会服务功能等5个方面共16个指标,构建了河流健康评价体系,并运用改进的层次分析法和模糊综合评价法相结合构建综合评价模型,对2条河流进行水生态健康评价。结果表明白河和潮河总体都处于“理想状况”,但生物状况均处于亚健康状态,建议后续应在白河和潮河生物方面持续开展水生态保护与修复工作,提升河流整体的健康水平。
A river health evaluation system was constructed based on 16 indicators of river hydrology,water quality status,river geomorphology,biological conditions and social services of the Bai River and Chao River,and a comprehensive evaluation model was built using an improved analytic hierarchy process and a fuzzy comprehensive evaluation method.The results showed that the Bai River and Chao River were in an"ideal condition"overall,but their biological conditions were sub-healthy.It is recommended that continuous water ecological protection and restoration work should be carried out on the biological aspects of the Bai River and Chao River to improve the overall health of the rivers.
