【摘要】近年来,呼伦湖渔业水域生态环境不断恶化,严重影响渔业生产,故于2009年对呼伦湖进行系统的调查监测。结果表明：呼伦湖水质盐碱化程度相对较高,富营养化比较严重。化学需氧量、非离子氨和氟化物等指标分别超出GB/T11607-89渔业水质标准7.2倍、9.6倍和4.6倍。生物资源量总体有所下降,浮游植物平均生物量为12.598 mg/L,浮游动物平均生物量为2.971 mg/L。%In recent years, the ecological environment of fishery water areas in Hulun Lake continues to deteriorate, which has a significant effect on fishery production. In view of this, we carried out systematic investigations and monitoring in Hulun Lake in 2009. The results showed that the Hulun Lake water was under relatively high salinization and, serious eutrophication. The chemical oxygen demand, non ionic ammonia, fluoride index 7.2 times, 9.6 times, and 4.6 times GB/T11607-89 fishery water quality standard respectively. Overall biological resources declined, the average biomass of phytoplankton was 12. 598 rag/L, and the average biomass of zooplankton was 2. 971 mg/L. 【总页数】5页(64-68)
