摘　　要：2006年的监测结果显示，温榆河CODM。BOD5、NH4-N、TP和TN含量大于我国地表水环境质量V类标准的1．3～11．7倍，主要污染物为总氮、氨氯和总磷；五项指标（SS、SD、CODMn,TP、TN）的TSIM值为75．11～119．45，属于富营养型水体。温榆河4个监测断面共检出浮游藻类6门148种，绿藻种类最多（48％），其次是硅藻（20．9％）、蓝藻（18．2％），优势种群均为富营养型水体指示种。温榆河浮游藻类密度大，平均为3179．01×10^4 cells／L，绿藻占优势（75．6％），蓝藻次之（14．6％）。The monitoring results in 2006 showed that the content of CODMn, BOD5 , NH4 - N,TP and TN in Wenyu River were respectively more than water environmental standards of the V type water 1.4 times,1.3 times,9.3 times,4. 3 times and 11.7 times. The total nitrogen, ammonia nitrogen and total phosphorus were major pollutants . The TSIM value of the five targets （SS, SD, CODMn, TP, TN ）in Wenyu River were between 75.11 and 119.45,it was longs to eutrophic water body. The phytoplankton communuty was composed of 148 species and dis- tributed among six division. The average density of pbytoplankton was 3179.01 x 104 cells/L, Chlorophyta was the dominance division （75.6%） ,and the second was Cyanophyta（14.6）. The dominance species of phytoplankton of all monitoring sections were indicator species of eutrophic water body.
