摘要:
根据江阴市四条主要内河锡澄运河、白屈港河、张家港河及横河的监测数据,分析叶绿素?a(Chla)的动态变化及其与理化水质因子的相关关系,并建立逐步回归多元线性模型,筛选与Chla显著相关的水质因子。结果表明,四条河道Chla存在明显的时间变化和空间分异。不同河道对Chla有显著影响的水质因子各不相同。总体来说,锡澄运河、白屈港河及张家港河Chla的主要影响因子为水温和外源输入,而横河除了这两个因子外,还受P和NH3-N影响。

Abstract:
According?to?the?monitoring?data?in?Xicheng?canal,?Baiqugang?river,?Zhangjiagang?river?and?Heng?river?of?Jiangyin?city,?the?relationship?between?chlorophyll?a?(Chl.a)?concentrations?and?physio-chemical?factors?was?investigated.?Besides,?the?factors?that?are?significantly?correlated?with?Chl.a?using?the?methods?of?multiple?linear?stepwise?regressions?were?selected.?The?results?indicated?that?there?was?an?obvious?temporal?and?spatial?variation?of?Chl.a.?Correlation?analysis?showed?that?the?significantly?important?environmental?factors?which?affect?Chl.a?were?not?always?the?same?in?four?investigated?rivers.?In?general,?the?main?environmental?factors?affecting?Chl.a?were?water?temperature?and?exogenous?inputs?for?the?first?three?rivers,?plus?phosphorus?and?ammonia?for?Heng?river.
