摘要
以廊坊市凤河为研究对象进行河流健康评价,为给凤河今后的河流健康治理提供方向,实现当地河流水生态健康发展的目标。在较为完善的评价标准基础上通过逐项评价和AHP-模糊数学模型评价2种方法对凤河进行科学、合理、适合本地实际情况的河流健康评价。构建了涵盖“盆”“水”生物、社会服务功能的4个准则层及对应下属12个指标层的评价体系。评价结果表明在逐项评价法中凤河健康状况为健康,在AHP-模糊数学模型评价中凤河隶属于“非常健康”等级测度0.411 0,隶属于“健康”等级测度为0.343 8,隶属于“亚健康”等级测度为0.223 9,隶属于“不健康”等级测度为0.021 3,隶属于“劣态”等级测度为0,廊坊经济技术开发区凤河流域在河岸带宽、底泥污染物、水质方面等方面表现不佳。提出的评价方法为受城市影响大、人工化高的河流开展健康评价提供参考。
This paper takes Fenghe River in Langfang City as the research object to conduct river health evaluation, which is expected to provide a direction for the future health management of Fenghe River and achieve the goal of healthy development of the water ecology of local rivers.On the basis of the relatively perfect evaluation standard, the scientific and reasonable health evaluation of Fenghe River is carried out by the item-by-item evaluation method and the AHP-fuzzy mathematical model, which is suitable for the local actual situation.An evaluation system is constructed, which consists of four criterion layers covering “basin”,“water”,“biology”,and social service functions and 12 subordinate index layers.The evaluation results show that Fenghe River is healthy according to the item-by-item evaluation method.In the evaluation of the AHP-fuzzy mathematical model, Fenghe River is “very healthy”,with a grade of 0.411 0.By this method, the grade of “healthy” is 0.343 8,and the grades of 0.223 9,0.021 3,and 0 denote the health status of “sub-healthy”,“unhealthy”,and “bad”,respectively.The Fenghe River Basin in Langfang Economic and Technological Development Zone has poor performance in terms of riparian bandwidth, sediment pollutants, and water quality.The proposed evaluation method can provide a reference for the health evaluation of rivers heavily influenced by cities and artificial interventions.
