| 摘 要： | 根据2009年11月在闽江的多学科综合调查结果,探讨了闽江下游及闽江口水域chl-a含量的分布特征及其与环境因子的关系.chl-a含量分布呈闽江上游水域较低(平均值为3.17μg/dm3),南北两港最高,而后向闽江口逐渐降低的趋势.大樟溪发生水华,chl-a含量高达170μg/dm3,南港chl-a含量最高值为71.4μg/dm3,北港chl-a含量最高值为67.6μg/dm3.闽江北港高含量chl-a区内存在一个低pH、低含量DO区;而南港chl-a含量与盐度、PO4-P含量、DIN含量呈十分显著的负相关关系,与pH、DO含量呈显著的正相关关系;马尾至闽江口水域chl-a含量与盐度、pH、DO含量则呈十分显著的负相关关系,与DIN含量、SiO3-Si含量呈十分显著的正相关关系.北港和南港的高含量chl-a区,分别与北岸福州市污水排放及南部大樟溪高含量chl-a的输入密切相关.

| Abstract: | Based on a multi-disciplinary investigation in Minjiang River in November 2009,the distribution of chl-a concentration and relations with environmental factors were discussed.The upper reach of Minjiang River had a lower concentration of chl-a（3.17 μg /dm3 in average） than that in the South and North branch and it decreased towards the sea in Minjiang Estuary.The maximum contentration of chl-a in the South and North branch were 71.4 μg /dm3 and 67.6 μg /dm3,respectively.There was a zone of high contentration of chl-a with low pH and low contentration of dissolved oxygen in the North branch.There were significant negative correlations of chl-a contentration to salinity,PO4-P,DIN,and positive correlations of chl-a contentration to pH and DO contentration in the South branch.However,it showed negative correlations of chl-a with salinity,pH,DO contentration and positive correlations with DIN,SiO3-Si contentration from Mawei port to Minjiang Estuary.The region of high chl-a contentration in the North and South branch were associated closely with the discharge of sewage from Fuzhou and high input of chl-a from Dazhang Creek. |
