【摘要】 2015—2016年期间对海河干流10个位点进行连续水质监控。受两岸土地利用类型影响,海河干流下游氮磷浓度水平显著高于中上游。受降雨、闸口、气候、生物作用、陆源污染等多重因素影响,氮磷营养盐的季节分布特征基本呈现为春夏季浓度水平较低,秋季陡然上升至峰值后于冬季平缓下降的趋势。相关性分析及因子分析表明,海河干流水体Chl.a含量受WT及氮磷含量的影响。更为持久的水质监测有助于进一步厘清海河干流藻华发生机制。更多还原

【Abstract】 Water samples were continuously collected at 10 sections of Hai River trunk stream from 2015 to 2016. Due to differences in land use along Hai River trunk stream,Nutrient levels in the lower reaches( S8 ~ S10) of the stream were much higher than in the other two sections,especially in the fall. The seasonal trend in eutrophication along Hai River trunk stream was the result of multiple effects of rainfall,dams,climate,biological action,point source pollution as well as non-point sourse pollution. It was found that the concentration of Chlorophyll α in Hai River Trunk Stream would be affected by temperature,N and P. Further more comprehensive and in-depth study of contaminant sources and a continuous monitoring of water quality of Hai River Trunk Stream,will be beneficial for the exploring the trends of water quality variation and the mechanism of algae bloom.更多还原
