Based on data collected at four stations in Daning River in the spring of 2004 and 2005, phytoplankton community structure, vertical distribution, abundance, biomass, C contents, diversity index, richness index and evenness index were studied. The causes of eutrophication and water blooms in Daning River were analysed and control measures were then put forward. The dominant species were Asterionella Formosa, Cryptomonas ovata, Cyclotella caspia, Stephanodiscus neoastraea in the spring of 2004 and those were Pandorina morum, Eudorina elegans, Cyclotella caspia, Cryptomonas ovata in the spring of 2005. Average cell densities, biomass, C contents in the spring of 2004 and 2005 were 171.1×10^5 cells/L, 12.2 mg/L, 1732.2g C/L and 113.1×10^5 cells/L, 10.1 mg/L, 1395.9g C/L, respectively.

报道了大宁河2004年春季和2005年春季浮游藻类的种类组成、垂直分布、数量、生物量以及C含量的调查结果，并应用多样性指数、丰富度指数和均匀性指数对其水质进行了综合评价；对大宁河蓄水后出现的富营养化现象和春季发生&水华&的原因进行了探讨，同时提出了控制水体富营养化的建议。2004年春季，藻类优势种为美丽星杆藻、卵形隐藻、里海小环藻和新星形冠盘藻；2005年春季的优势种为实球藻、空球藻、里海小环藻和卵形隐藻。2004年和2005年的细胞密度、生物量和C含量分别平均为171.1×10^5 cells/L，12.2 mg/L，1732.2g C/L和113.1×10^5 cells/L，10.1 mg/L，

This paper analyzes the trends and variations of cross-section profile parameters in lower Yellow River with the methods of time series analysis. The analysis results show that since 1950s, cross-section profile parameters in lower Yellow River have change with trend, especially after 1990s, the bankfull discharge and bankfull area all show decreasing trends at all the four stations. The bankfull width at Huayankou, Gaocun and Lijin station and the average depth at Huayuankou and Aishan station and the maximal depth at Gaocun station show decreasing trends while the bankfull water level at Gaocun and Aishan station and width-depth ratio at Aishan station show increasing trends.

本文采用时间序列分析的方法对黄河下游河道断面形态参数变化趋势及其变异点进行了分析，分析结果表明从20世纪50年代以来，断面形态参数发生了趋势性变化，特别是90年代以来各站平滩流量和平滩面积均有显著的下降趋势，花园口站、高村站和利津站平滩河宽出现了显著下降趋势，花园口站、艾山站平均水深显著下降，高村站和艾山站的平滩水位显著抬高，艾山站的宽深比也有显著增大的趋势。

It is shown from the assessment results that (1) both the TN and TP fluxes discharged from the Changjiang River to the Changjiang River estuary sea area increased continuedly, the DIN concentration in the sea areas increased continuedly, and the Si concentration decreased continuedly, which resulted in the significant changes in N/P/Si ratios;(2) the chlorophyll a concentration in the sea areas increased continuedly, and the significant changes in community structure of phytoplankton occurred;(3) the species and biomass of benthos declined greatly, and the bottom oxygen-poor water area increased significantly;(4) the range and occurrence frequency of red tide events in the sea areas increased greatly, and the algal toxic infection events of mussel were frequently found in the sea areas.

结果表明，长江向长江口海域输送总氮和总磷通量持续增大，长江口及其邻近海域无机氮浓度持续增高而硅浓度持续下降，并由此导致N/P/Si与比值的显著变化；该海域叶绿素a浓度持续增大，浮游植物群落结构也发生了显著变化；该海域底栖生物种类和生物量都大大减少，底层水低氧区面积也显著扩大；该海域赤潮事件无论是规模还是频率都大大增加，藻类毒素DSP/PSP贻贝传染事件也时有发生。
