本文报道了１９８２～１９９０年５次对北门滩生物资源的调查结果。该湖水型为ＮａＭｇｓＯ＿４Ｃｌ型，平均盐度６．９２ｇ／Ｌ，ｐＨ值８．６～１０．３，碱度１０．３ｍｍｏｌ／Ｌ．共见到９０种浮游植物、６４种浮游动物、４种底栖动物和７种鱼类。浮游生物优势种类有衣藻、孟氏小环藻、舟形藻、湖生卵囊藻、铜绿微囊藻、绿裸藻、啮蚀隐藻、褶皱臂尾轮虫、壶状臂尾轮虫、角突臂尾轮虫、环顶巨腕轮虫、大型、等刺温剑水蚤等．浮游植物生物量１７．８５ｍｇ／Ｌ，浮游动物和底栖动物的平均生物量分别为８．０８ｍｇ／Ｌ和０．００３ｇ／ｍ￣２．文中还讨论了北门滩水化学和水生生物学特点并与硝池进行了比较。
This paper reports the results of five surveys of biological resources in Beimen County from 1982 to 1990. The lake water type NaMgsO_4Cl type, the average salinity 6.92g / L, pH value of 8.6 to 10.3, basicity 10.3mmol / L. A total of 90 species of phytoplankton, 64 species of zooplankton, 4 species of zoobenthos and 7 species of fish were found. The dominant species of plankton are Chlamydomonas reinhardtii, Cyclotella spp., Navicular algae, Oocysts lacustris, Microcystis aeruginosa, Euglena gracilis, echinoderms, Brachionus plicatilis, Brachionia pratense, Angle Bursa rotifer, Ring top giant rotifers, large, and other thorns warm water flea. The phytoplankton biomass was 17.85 mg / L, and the average biomass of zooplankton and zoobenthos were 8.08 mg / L and 0.003 g / m ~ 2, respectively. The paper also discusses the characteristics of water chemistry and aquatic biology in Beimen area and compares it with that of nitrate pool.
