浮游植物生物量与ｐＨ、总碱度、总硬度、含盐量呈抛物线关系。在ｐＨ７．７５～８．７５，总碱度 ３．５～６ ｍｍｏｌ／Ｌ，总硬度 ９．５～１４．５ ｍｍｏｌ／Ｌ，含盐量 ２．３～３．７ ｇ／Ｌ时，浮游植物发生机会最多，生物量最高。
Phytoplankton biomass and pH, total alkalinity, total hardness, salinity showed a parabolic relationship. At pH7.75-8.75, total alkalinity 3.5-6 mmol / L, total hardness 9.5-14.5 mmol / L, salt content 2.3-3.7 g / L, the plankton Plants have the highest chance of occurrence and the highest biomass.
