春季九山湖细菌生理类群的分布与主要环境因素的相关性分析

本文研究了九山湖中7种细菌生理类群：产淀粉酶菌（AB），产蛋白酶菌（PB），有机磷细菌（OPB），无机磷细菌（IPB），硝化细菌（NB）及反硝化细菌（DNB），产脂肪酶菌（LB）的分布，以及它们与主要环境因素的相关性，统计分析表明，春季，在九山湖中，OPB与总磷存在显著的正相关，NB与NH^ 4-N存在显著的正相关，DNB与NO^-2-N存在显著的正相关，LB与油脂间存在显著的正相关，OPB，IPB，NB，PB，DNB，AB与水温无显著相关性，而且除DNB与溶解氧（DO）存在一定的负相关外，其余细菌与DO存在不同程度的正相关。

The Correlation Between the Distribution of Physiological Group of Bacteria and Main Environmental Factors in Jiushan Lake

The distribution of seven kinds of physiological groups of bacterial amylase producing bacteria(AB), lipase producing bacteria(LB),proteinase producing bacteria(PB),organic phosphate dissolving bacteria(OPB),inorganicphosphate dissolving bacteria(IPB),nitrifier(NB) and disnitrifier(DNB) in Jiushan Lake and their correlation between physiological groups of bacteria with main environment factors were studied.Statistical analysis indicated that the correlation between TDP and the amount of OPB is quit positive.The correlation between NH 4 N and the amount of NB is quit positive,the correlation between NO - 2 N and the amount of DNB is quit positive,the correlation between oil and the amount of LB is quit positive.The correlation between W T and the amount of OPB, IPB, NB,DNB,AB are not singnificant.Except the correlation between OD and DNB is negative.Others physiological groups of bacteria is positive.
