摘要
研究了白洋淀几个主要淀区春季浮游植物的生物量、叶绿素含量和生产量。各淀区浮游植物生物量（ｍｇ／ Ｌ） 平均为４５．２６１，以寨南最大（１１３．１３８），藻 淀最小（０．８６２）；叶绿素含量（μｇ／ Ｌ） 平均为７．５７３ ３，其中南刘庄最大（１７．６９０ ４），藻 淀最小（０．２４５ ７） ；最高生产层以碳计的日产量（ｇ／（ｍ３ ·ｄ））平均为０．２８５，其中南刘庄最大（１．０５５），藻 淀最小（０．０１５） ，水柱日产量（ｇ／（ｍ２ ·ｄ）） 平均为０．４３１，其中寨南最大（１．００１），藻 淀最小（０．０１３）。
This article reported the biomass, chlorophll content and production of phytoplankton in the Lake Baiyangdian, in April, 1998.The average biomass (mg/L) was 45.261. The maximum biomass of 113.138 occurred in Zhainan lake region and the minimum biomass of 0.862 in the Zaozhadian lake region. The average chlorophyll content (μg/L) was 7.573 3. The maximum chlorophyll content of 17.690 4 occurred in Nanliuzhuang lake region and the minimum chlorophyll content of 0.245 7 in the Zaozhadian lake region. The average daily yield (carbon)of the highest productive layer was 0.285 g/(m3·d). The maximum daily yield of the highest productive layer of 1.055 g/(m3·d) occurred in the Nanliuzhuang lake region and the minimum daily yield of the highest productive layer of 0.015 g/(m3·d)occurred in Zaozhadian lake region. The average daily yield of the water column was 0.431 g/(m2·d). The maximum daily yield of the water column of 1.001 occurred in Zhainan lake region and the minimum daily yield of the water column of 0.013 occurred in Zaozhadian lake region.
