盐碱地鱼池水化学因子与浮游植物的调查研究

Investigation on Chemical Water Factors and Phytoplankton in Ponds on the Saline-alkali Land

对山东黄河两岸和河口地区盐碱地鱼池的水化学因子与浮游植物进行了调查研究，确认鱼池水型属和型的氯化水，ｐＨ变化在７．６～８．９之间，盐度在０．９～８之间，营养盐含量比一般淡水鱼池低，浮游植物甚至不如小型水库、湖泊丰富。

An investigation was conducted on water chemical factors and phytoplankton in pondson the saline-alkali land in the coastal region along the Yellow River in Shandong and in its estuarialarea. According to the investigational result we confirmed that the water type belongs to oxidized waterof and type in which pH varies between 7.6～ 8.9,salinity between 0.9～8 and thecontent of nutrient salt is generally lower than that in the fresh water ponds and the content of phytoplankton is even far lower than that in the small-tuped reservoir and lakes.
