摘要: 于1998年7~8月间在山东省高青县赵店乡大芦湖养殖场选取一口盐碱池塘的池水为实验用水,用粗盐和碳酸氢钠调节盐度和碱度,以研究盐碱池塘在盐度和碱度升高的情况下其化学、生物因子的变化趋势.结果表明,盐碱池塘中重碳酸盐碱度的升高会在短时间内降低水体pH值、钙离子浓度和COD;但碱度为6.64±0.40mmol·L-1~13.47±0.31mmol·L-1对浮游生物不会产生显著的不良影响.盐度为2.10±0.22g·L-1~11.29±0.99g·L-1会引起浮游生物生物量的降低,并减少浮游生物的种类,降低其多样性指数,影响浮游生物群落结构组成.

Abstract: This paper dealt with the effects of increasing salinity and alkalinity on the chemical and hydrobiological factors in saline alkaline ponds.The experiment was conducted in Daluhu Aquaculture Company,Gaoqing County,Shandong Province during July and August,1998.Raw salt and NaHCO-3 were used to adjust the salinity and alkalinity.The results showed that increasing alkalinity from HCO-3- rsulted in the reduction of pH value,calcium ion concentration and COD in a short term.When alkalinity was increased from 6.64?0.40 to 13.47?0.31 mmol稬-1,no significant effect on plankton was observed. However,when salinity was increased from 2.10?0.22 to 11.29?0.99 g稬-1,it decreased the plankton biomass,species number and diversity index decreased,and affected the composition of plankton community structure.
