| 摘 要： | 2005年3月～2008年7月,对大宁河5个采样断面的富营养化现状进行监测,并由此建立了Chla浓度预测模型。结果表明,处于回水腹心区的断面水体易发生富营养化现象,其优势种在春季时段主要是拟多甲藻和梅尼小环藻,而夏季时段主要是美丽星杆藻和水花微囊藻;Chla与CODMn、TN和TP呈显著正相关,而与SD呈显著负相关（α=0.05）。以2009～2010年监测数据作为案例进行验证,多数模型Chla预测值与实测值吻合较好,相对误差〈±70%,故可以用Chla预测值对水体富营养化状况作出初步预测。 |

| Abstract: | The eutrophication actualities of five sampling transect have been monitored from March 2005 to July 2008 in Daning River.It showed that it was much easier to break off eutrophication phenomena for transect in the central backwater reach.Meanwhile,the dominant species of eutrophication water were Peridiniopsis sp.and C.meneghiniana in spring,but were A.formosa and M.flos-aquae in summer.The Chlorophyll-a(Chla) prediction models based on the monitoring data were founded.It indicated there were significant po... |
