府河汛期生物多样性及水生态环境质量状况评价

Evaluation of biodiversity and water ecological environmentquality of Fuhe River during flood season

以常年有水入白洋淀的府河为研究对象,从河流浮游动植物、底栖生物、鱼类、大型维管束植物等方面开展汛期府河水生态环境质量状况调查与评价。通过府河水生态环境质量综合评价指数FEQI结果显示:府河水生态环境质量状态为上游良好、中游和下游中等。研究发现,不同水文条件下水生生物密度及生物量存在局部差异;府河的生物多样性趋于平稳。总体来看,保定市府河水生态环境质量状态在中等-良好之间,上游段良好,中游下游河段水质中等。

Taking the Fuhe River,which has water flowing into Baiyangdian all year round,as the research object,a survey and evaluation of the ecological environment quality of the Fuhe River during the flood season was conducted from the aspects of planktonic flora and fauna,benthic organisms,fish and large vascular plants.The comprehensive evaluation index FEQI for the ecological environment quality of Fuhe River showed that the ecological environment quality status of Fuhe River was good in the upstream,moderate in the middle and downstream.Research has found that there were local differences in the density and biomass of aquatic organisms under different hydrological conditions.The biodiversity of Fuhe River tended to stabilize.Overall,the ecological environment quality of the Fuhe River in Baoding City ranged from medium to good,with good water quality in the upstream section and moderate water quality in the middle and downstream sections.
