[目的]通过研究抚河源头水体中浮游动植物的种类及湿地植被分布状况,科学评价抚河源头水生生态环境.[方法]在形成抚河源头活水的抚河第一流--广昌驿前血木岭海拔900 m以上的山涧溪流处随机设置10个采样点,在丰水期进行为期3个月的浮游动植物群落及湿地植被调查.同时研究水温、pH值、总氮、总磷和高锰酸盐指数等.[结果]共检出7大类浮游动植物45 种,其中绿藻数量较多,河生集星藻等优势种明显,未检出甲藻门、枝角类以及轮虫等浮游动植物;湿地植物不仅有大型的乔木,还有灌木、草本及藤本植物,初步统计植物隶属36科46属,共计50种.[结论]抚河源头水生生态环境良好,水质为Ⅰ类水.

[Objective] Through investigating the species of zooplankton and phytoplankton and distribution of hygrophilous vegetation in Fu River's headstream, the aquatic ecological environment in Fu River's headstream was scientifically evaluated. [Method] 10 sampling points were established randomly along No.1 stream of Fu River-the stream in Xuemuling Mountain of Yiqian in Guangchang at the altitude of 900 meters. The zooplankton, plankton and hygrophilous vegetation were in wet season investigated for three months. And the water temperature, pH value, total nitrogen, total phosphorus and permanganate index were studied at the same time. [Result] 45 kinds of zooplankton and phytoplankton were detected in total, belongs to 7 classes. Among them, the amount of green algae was relatively high and Actinastrum fluviatile and other dominants were considerable. Some zooplankton and phytoplankton, including Pyrrophyta, Cladocera or Rotifer had not been detected. The hygrophilous vegetation included arbor, shrub, herbage, and liane. 36 families, 46 genera;50 species of hygrophilous vegetation were preliminarily counted. [Conclusion] The aquatic ecological environment of Fu River's headstream was good and the water was ClassⅠ.
