摘　　要：报道１９９４年７月和９月对克旗四座水库进行水化学和水生生物调查的结果，１）库水盐度０．１２‰～０．１５‰；ＡＬＫ平均１．４３ｍｍｏｌ／Ｌ；Ｔ·Ｈ平均１．３７ｍｍｏｌ／Ｌ；水化学类型按阿列金分类法，响水水库属Ｃ型，其余三座均属碳酸盐类钙组Ⅰ型水（）．２）共见到４０属浮游植物和３１种浮游动物。底栖动物和鱼类种类很少。浮游植物平均生物量１．７８～１２．４１ｍｇ／Ｌ，优势种为直链藻、小环藻、角星鼓藻、角甲藻、微囊藻、壳虫藻和隐藻。浮游动物平均生物量１．０～２．１６ｍｇ／Ｌ优势种为长刺水蚤、长额象鼻水蚤、螺形龟甲轮虫、长三肢轮虫和晶囊轮虫。底牺动物平均生物量０．３７～１．２０ｇ／ｍ￣２，主要是水蚯蚓和几种双翅目幼虫．３）文中讨论了几座水库的水化学和水生生物特点，并探讨了营养类型和鱼产力问题。Hydrochemistry and hydrobiology of four reservoirs in Keshi Ketengqi,Inner Mongolia were surveyed in July and September of 1994. Salinity varied from 0.12‰ to 0.15,alkalinity averaged 1. 43 mol/L and total hardness was 1.37 mmol /L on average.According to the Classification of Hammer, Reservoir Xiang Shui belongs type ,and the others are ,Forty genera of phytoplankton and thirty-one species of zooplankton were found in the reservoirs. Only a few benthos and fishes appeared in the waters.The biomass of phytoplankton was between 1.78 mg/L and 12.40 mg/L, predominantly Melosira,Cyclotella ,Staurastrum,Ceratium,Microcystis, Trachelomonas,and Cryptomonas.The biomass of zooplankton varied from 1.00 mg/L to 2.16 mg/L,with prodominant species of Daphnia longispina,Bosmina longirostris, Keratella cochlearis, Filinia longiseta and Asplanchna sp. The benthic biomass was between 0.37 g/m￣2 and 1.20g/m￣2,predominantly Tubifex and Diptera larvae. The relationship between hydrochemical and hydrobiological characteristics and productivity of fish isdiscussed in detail。
