本文报道1982、1984和1990年对内陆盐水湖——硝池进行水化学和水生生物调查的结果。1)湖水盐度平均10.3～78.3g/L,水化学类型按Hammer分类法属NaMgSO_4Cl型。2)共见到42属浮游植物和62种浮游动物,底栖动物和鱼类的种数很少。浮游植物平均生物量1.33～26.6mg/L,优势种有:舟形藻、孟氏小环藻、盐藻、卡德藻、扭曲蹄形藻、普通小球藻、湖生卵囊藻、啮蚀隐藻、光甲藻、裸藻、小三毛金藻、蓝球藻和席藻。浮游动物平均生物量0.07～20.1mg/L,优势种有:褶皱臂尾轮虫、环顶巨腕轮虫、单趾轮虫、卤虫、象鼻溞,蒙古裸腹溞、细巧华哲水蚤、亚州后镖水蚤、等刺温剑水蚤和短角异剑水蚤。底栖动物生物量平均6.6(<1～42.5)mg/m~2,以二齿沼摇蚊幼虫占优势。3)文中讨论了硝池的水化学特点、浮游生物和生态因子的关系以及渔业利用等问题。
This article reports the results of the hydrochemical and aquatic surveys of inland lagoons-nitrophones in 1982, 1984 and 1990. 1) The salinity of the lake is 10.3 ~ 78.3g / L on average, and the chemical type of water is NaMgSO_4Cl by Hammer classification. 2) A total of 42 phytoplankton species and 62 species of zooplankton were found, with fewer species of zoobenthos and fish. The average biomass of phytoplankton was 1.33 ~ 26.6mg / L, the dominant species were: Navicula algae, Cyclotella monocytogenes, Dunaliella salina, Cade alga, Twisted Cholera, Chlorella vulgaris, Lake Oocysts, Cryptophyta, Photinuclear, Euglena gracilis, Chlamydomonas reinhardtii, Chlorella and mycelia. The average biomass of zooplankton was 0.07 ~ 20.1mg / L, the dominant species are: Brachionus plicatilis, Giant rotundiformes, Rotifers, Artemia, Trichosanthes, Mongolian gibbons, Fleas, Asian dart darter, and other thorns temperature Daphnia magna and short-angle Ishii Daphnia. The average benthic biomass was 6.6 (<1 ~ 42.5) mg / m ~ 2, and the dominant species were B. chironomus larvae. 3) The paper discusses the chemical characteristics of the nitrate pool, the relationship between plankton and ecological factors and the use of fisheries and other issues.
