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。
The results of the survey of hydrochemical and aquatic biota in the four reservoirs of Keqi in July and September of 1994 were reported. 1) The salinity of the water in the reservoir ranged from 0.12 ‰ to 0.15 ‰, and the average ALK was 1.43 mmol / L. The T · H An average of 1.37mmol / L; water chemistry type according to Aleinking classification, Xiangshui Reservoir is C type, the remaining three are carbonate type calcium Ⅰ group (). 2) A total of 40 phytoplankton and 31 species of zooplankton were found. Minimal zoobenthos and fish species. The average biomass of phytoplankton was 1.78 ~ 12.41 mg / L, and the dominant species were Stratiotes algal, Cyclotella, Prunus dactylorhiza, Rhodophyta, Microcystis, Echinochloa crusgalli and Cryptophyta. The dominant biomass of zooplankton was 1.0 ~ 2.16mg / L. The predominant species were Daphnia magna, Daphnia magna, Helicoverpa armigera, Rotifers and Cyst rotifers. At the end of sacrificial animals, the average biomass of 0.37 ~ 1.20g / m ~ 2, mainly water earthworms and several Diptera larvae. 3) The hydrochemistry and aquatic characteristics of several reservoirs are discussed and the types of nutrients and fish productivity are discussed.
