１９９４年夏季和秋季调查表明，岗更湖属碳酸盐类镁组Ⅰ型（ＣｍｇⅠ）淡水湖，水体总含盐量０．２３～０．２９；ｐＨ９．６１（９月份），总碱度２．６５～９．６０ｍｍｏｌ／Ｌ．该湖有１２种浮游植物和７类浮游动物，仅于秋季见到水生昆虫和水丝蚓．浮游植物的优势种在夏季和秋季均为蓝藻，浮游植物、浮游动物和底栖动物的平均生物量（７月和９月）分别为４５ｍｇ／Ｌ、２．６ｍｇ／Ｌ和０．２２８ｍｇ／Ｌ；浮游植物初级产量（Ｏ２）平均为４．２５ｇ／ｍ２．本文讨论了生物区系与水化因子及鱼产潜力之间的相互关系，并将该湖水化学和水生生物学调查的结果与７０年代的进行了比较．
The summer and autumn 1994 surveys showed that the total salt content of water in the Ganggishi carbonate magnesium group Ⅰ (CmgⅠ) was 0.23 ~ 0.29, pH9.61 (September), total alkali Degrees 2.65 ~ 9.60mmol / L. The lake has 12 kinds of phytoplankton and 7 kinds of zooplankton, only in the fall to see aquatic insects and water earthworms. The dominant species of phytoplankton were cyanobacteria in summer and autumn, and the average biomass of phytoplankton, zooplankton and zoobenthos in July and September were 45 mg / L, 2.6 mg / L and 0.228 mg / L, respectively Phytoplankton primary production (O2) averaged 4.25g / m2. This paper discusses the interrelations between biota and hydration factors and fish productivity and compares the results of the Lake Chemistry and Aquatic Biology surveys with those from the 1970s.
