英文摘要	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.; 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.; 福建省科技合作重点项目资助项目(2009I0025)
