摘  要:
研究河南省农业面源污染的来源及污染负荷,对河南省农业面源污染治理具有重要意义。采取输出系数模型法,估算了2014年河南省农业面源污染物总氮和总磷负荷量。结果表明:2014年河南省农业面源污染物总氮负荷量是总磷负荷量的6.7倍,分别是3.87×10~5,5.73×10~4 t/a。三种不同污染源类型总氮负荷贡献率的大小顺序为:耕地>畜禽养殖>农村生活;总磷负荷贡献率的大小顺序为:畜禽养殖>耕地>农村生活。河南省农业面源污染程度区划可分为5个区域:南阳市和驻马店市为重度污染区,周口市、商丘市和信阳市为较重度污染区,新乡市、安阳市、洛阳市、开封市、平顶山市、郑州市、许昌市为中度污染区,濮阳市、三门峡市、鹤壁市、焦作市、漯河市为较轻污染区,济源市为轻度污染区。研究表明,河南省农业面源污染主要来源于耕地、畜禽养殖和农村生活,面源污染在可区划为5个区,区划可为河南省面源污染的分区治理提供科学依据。

摘  要:
Study on the sources and loads of agriculture non-point pollution can play an important role in the agriculture non-point pollution control.Output coefficient model was used to estimate the agricultural nonpoint source pollutants total nitrogen and total phosphorus load in He′nan Province in 2014.The results show that:in 2014,loads of agricultural non-point source pollutants of total nitrogen and total phosphorus in He′nan were 3.87×10~5 t/a and 5.73×10~4 t/a,respectively.The contribution rates of different kinds of pollution of non-point source pollutants to total nitrogen decreased in the order:the cultivated land>livestock farming>rural living;the contribution rates to total phosphorus load decreased in the order:livestock and husbandry>the cultivated land>rural living.Agricultural non-point source pollution degree zones can be divided into five types,Nanyang and Zhumadian cities are the heavily polluted areas;Zhoukou,Shangqiu and Xinyang are the more severe pollution area;Xinxiang,Anyang,Luoyang,Kaifeng,Pingdingshan Zhengzhou,Xuchang are the moderate pollution area;Puyang,Sanmenxia,Hebei,Jiaozuo,Luohe are the lighter pollution areas;Jiyuan City is lightly polluted area.This study suggested that agriculture non-point pollution sourced from farmland,livestock and poultry farming,and rural living,and non-point pollution areas could be classified into five regions,which could provide the scientific basis for the agriculture non-point pollution control.
