摘　　要：通过对阿什河哈尔滨段农业区和工业区柱状沉积物的无机磷(IP)、有机磷(OP)、钙结合态磷(Ga-P)、铁铝结合态磷(Fe/Al-P)、总磷(TP)以及有机碳(TOC)的测试和分析,研究了阿什河哈尔滨段沉积物各形态磷的时空分布特征,结果表明工业区的污染程度远大于农业区,农业区的污染主要来源于农业化肥的流失以及生活污水的排放,工业区的污染来源于工业废水和生活污水,通过单项污染指数法对沉积物进行污染评价,结果表明TP存在一定的安全风险。Through the analysis of inorganic phosphorus(IP),organic phosphorus(OP),calcium-bound phosphorus(Ga-P),iron-aluminum-bound phosphorus(Fe/Al-P),total phosphorus(TP)and organic carbon(TOC),and the temporal and spatial distribution characteristics of various forms of phosphorus in the sediments of the Harbin section of the Ashi River were studied.The pollution in the area mainly comes from the loss of agricultural fertilizers and the discharge of domestic sewage,while the pollution in the industrial area comes from industrial wastewater and domestic sewage.The single pollution index method is used to evaluate the sediment pollution.The results show that TP has certain safety risks.

关 键 词：沉积物 污染评价 磷形态 分布特征
