【摘要】 研究了三角帆蚌滤食富营养化水体中藻类的能力.发现三角帆蚌能有效地清除水体中的叶绿素a.通过方差分析的方法得出在96 h即达到显著的清除效果,并且当蚌密度在18.75只/m3时(本实验水体中藻类密度为106个/mL左右)清除的效果最佳.还对实验的结果进行了函数的拟合,发现在贝类滤食过程中叶绿素a含量和时间之间存在对数函数关系.本文提示利用双壳贝类净化富营养化水体是一条可行的途径.更多还原

【Abstract】 Hyriopsis cumingii Lea’s ability to filter algae in eutrophic water was studied.Hyriopsis cumingii Lea was found to be able to eliminate chlorophylla in water efficiently.By analysis of variance,we concluded that the effect of elimination was remarkable after 96h,and that when the density of mussels was 18.75 per m~3 while the density of algae was about 10~6 per mL,the effect of elimination was the best.The function analogue of the experimental results indicated that the content of chlorophyll-a and the time had a logarithm function relation during the purifying process.The study suggested that it was a feasible way to purify eutrophic water with bivalves.更多还原
