摘要
报道了１９８２～１９９０年间对盐池生物资源所进行的５次调查的结果。该湖水型一般为ＮａＭｇＳＯ４Ｃｌ型或ＭｇＮａＣｌＳＯ４型。盐度４．９５～３１１．５ｇ／Ｌ，ｐＨ值７．５～１０．６，碱度２．５～２２．４ｍｍｏｌ／Ｌ。共见到５３种浮游植物、４７种浮游动物、５种底栖动物和１种鱼类。浮游生物优势种类主要有盐藻、隐头舟形藻、舟形藻、孟氏小环藻、小颤藻、普通小球藻、湖生卵囊藻、卤虫、褶皱臂尾轮虫、蒙古裸腹氵蚤、短角异剑水蚤等。笔者针对盐池的水化学和生物特点进行了讨论，并与硝池、北门滩进行了比较。
This paper discribes the results of the chemical and biological surveys of Lake Yanchi located in Jinnan Region, Shanxi Province, China, during 1982￣1990. The water type of the lake is NaMgSO 4Cl or MgNaClSO 4 subtype, the salinity 4.95￣311.5 g/L, pH value from 7.5￣10.6, alkalinity 2.5￣22.4 mmol/L. Fifty three species of phytoplankton, 47 species of zooplankton, 5 species of zoobenthos and 1 species of fish were found in the lake. As far as plankton, the dominant species are Dunaliella salina, Navicula cryptocepha, Navicula spp ., Cyclotella meneghiniana, Oscillatoria tenuis, Chlorella rulgaris, Oocystis lacustris, Artemia sp. , Brachionus plicatilis, Moina mongolica, Apocyclops royi and ect. The chemical and biological features as well as utilization of the resource in the lake were discussed, and compared with the other saline lakes.
