【摘要】 本文报道了1981年6月和1982年5月两次对扎陵湖、鄂陵湖水化学、水生生物和鱼类学的调查结果。两湖的盐度较低分别为O.38‰和O.36‰,均属重碳酸盐型的淡水湖。两湖共发现浮游植物63种、浮游动物21种、底栖生物20种和鱼类8种。扎陵湖浮游植物、浮游动物和底栖生物的平均生物量分别为0.9毫克/升,O.2毫克/升,0.9克/米~2;鄂陵湖分别为O.5毫克/升,0.4毫克/升,1.6克/米~2。各类饵料生物的优势种为硅藻、金藻、轮虫、桡足类、摇蚊幼虫和寡毛类。 作者分析了两湖的水化学、水生生物和鱼类学特点,提出了开发利用其鱼类资源的意见。更多还原

【Abstract】 The investigations on hydrochemisty, hydrobiology and ichthyology of Zhaling Lake and Eling Lake were carried out in June 1981 and May 1982. The salinities of the two lakes were 0.38‰ and 0.36‰ respectively. The two lakes belong to the fresh water lake of carbonate type in chemistry. 63 species of phytoplankton, 21 species of zooplankton, 20 species of benthos aod 8 species of fish were found in the two lakes. The average biomass of phytoplankton, zooplankton and benthos were 0.9 mg/l, 0.2 mg/l and 0.9g/m~2 respectively in zhaling Lake, and those in Eling Lake were 0.5 mg/l, 0.4mg/l and 1.6g/m~2 respectively. The dominant species of the prey living things were Bacillariophvta, Chrysotphyta, rotifer, copepod, larvae of Chironomidae and Oligochaeta.The authors have analysed the features of hydrochemisty, hydrobiology and ichthyology of the two lakcs meanwhile make suggestions of exploiting and ultilizating the fishery resoureses of the two lakes。更多还原
