摘要

为评估运城市典型流域水生态健康状况，本研究于2024年8月对运城市汾河、涑水河及伍姓湖5个代表性样点的浮游植物群落进行了系统调查。结果显示：5个调查样点共鉴定浮游植物6门49属73种，以硅藻门、绿藻门和蓝藻门为主；浮游植物平均密度为1.870 3×10

cells/L，蓝藻门占比达92.52%；平均生物量为21.38 mg/L，硅藻门贡献最大（75.16%）。浮游植物优势种主要为假鱼腥藻、细鞘丝藻等蓝藻，存在水体富营养化风险。多样性指数表明，水体整体处于中度污染水平。基于此，提出了“控源截污为基础、生态修复为核心、预警监测为保障”的综合治理对策，以期为运城市夏季丰水期水环境精准治理提供科学依据。

Abstract

To assess the health status of the aquatic ecosystem in typical river basins of Yuncheng City， a systematic investigation was conducted on the phytoplankton communities at five representative sampling sites in the Fenhe River， the Sushui River， and the Wuxing Lake in August 2024. The results showed that a total of 73 species were identified in five survey sites， belonging to 49 genera and 6 phyla， primarily dominated by

Bacillariophyta

，

Chlorophyta

， and

Cyanophyta

. The average phytoplankton density was 1.870 3×10

cells/L， with

Cyanophyta

accounting for 92.52%. The average biomass was 21.38 mg/L， with

Bacillariophyta

contributing the most （75.16%）. The dominant species were mainly cyanobacteria of

Pseudanabaena

and

Leptolyngbya， etc.，

which posed a risk of eutrophication. The diversity

index indicated that the water body was moderately polluted. Based on this， the comprehensive management strategy of "controlling the source and intercepting pollution as the basis， ecological restoration as the core， and early warning and monitoring as the guarantee" was proposed， aiming to provide a scientific basis for the precise management of the water environment in Yuncheng City.
