【摘要】 根据1980～2003年对大伙房水库及上游流域水质调查情况,对库区主要营养物(N、P)等进行了分析。结果表明:水库主要污染物为氮、磷。上游流域的种、养殖、生活污水是水库氮、磷污染的主要因子。论述了水库营养物(N、P)物流来源及平衡关系和污染份额。确立了水库汇水区内存在的问题和治理对策。更多还原

【Abstract】 The levels of main nutrients, nitrogen (N) and phosphorus (P), were monitored and analysed in Dahuofang reservoir and its tributaries from 1980 to 2003. The results showed that the nitrogen and phosphorus, as the main pollutants, were principally derived from agriculture and domestic sewage. The paper reported the nitrogen and phosphorus budgets, and pollution share. The main ecological problems and countermeasure were discussed.更多还原
