摘　　要：报道了连环湖他拉红泡（卡拉白鱼放养场）的水质季节变化动态及浮游生物组成。结果表明：该水水质透明度为23～35cm，pH=8．00～8．82，硬度为1．2854～3．3315mmol／L，碱度为6．8796～9．6179mmol／L。水呈碱性，水型属碳酸盐类、镁组Ⅰ型水（CME）和软水。水中COD含量为8．56～11．36mg／L；主要营养元素总氮为0．5455～0．7618mg／L，总磷为0．4315～0．4950mg／L，属于中富-富营养型湖泊。湖水中多数理化组分在季节分布上差异不明显，个别测定值在5月（枯水期）较高，9月（平水期）出现回落。浮游植物5个门37个种属，其中硅藻门、绿藻门、蓝藻门3个门有34个种属，占98．93％；浮游植物总平均量为687．56×10^4ind／L，生物量8．8883mg／L。浮游动物共4类31个种属，数量上以原生动物、轮虫为主，占77．67％，生物量桡足类最大，为1．1930mg／L，浮游动物总平均量为270．690ind／L。The monitoring data of water and season changes and plankton of Talahong in Lianhuan Lake were reported. The results indicated that its water quality was good, with transparency of 23--35 cm, pH = 8.00--8.82, DK 1. 285 4--3. 331 5 mmol/L, Alk. 6. 879 6--9. 617 9 mmol/L, and the water type C1^Mg as well as soft water. COD is 8.56--11.36 mg/L. The content of major nutrient elements such as TN is 0. 545 5--0. 761 8 mg/L, which was lower than TN of main lakes in Heilongjiang Province, TP （0. 431 5--0. 495 0 mg/L） is normal. The lake belongs to eutrophication lake. The majority of data did not change obviously during different seasons. However, a few data were high in May, while some were low in September. Phytoplankton belong to 5 Phylum-37 Genus or Species,the most quantity are Bacillariophyta,Chlorophyta and Cyanophyta, the rate is 98.93%. Total average quantity of Phytoplankton is 687.56 ×10^4ind/L, and biomass is 8. 888 3 mg/L; Zooplankton belong to 4 Phylums-31 Genus or Species, protozoon and rotifer have the most quantity（77.67%）, Copepoda have the most biomass（1. 1930 mg/L）, total average quantity of Zooplankton is 270. 690 ind/L.
