丹江口库区湖北水源区农业面源污染现状调查及评价
摘要采用综合调查的方法对丹江口库区湖北水源区31个乡镇的农业面源污染现状进行调查用产污系数法排污系数法测算区域内各类农业污染源产生与排放污染物的总量并引入等标污染负荷法分析和评价该区域农业面源污染现状结果表明在该区域内农业面源主要污染物TNTP和COD的产生量分别为20669324093和1654018t排放量分别为14322816183和454665t种植业源为该区域农业面源的主要污染源其等标污染负荷占所有农业面源等标污染总负荷119678tPO43的5779水产养殖业源农村生活源和畜禽养殖业源所占比例分别为14911425和1305TNTP为该区域农业面源的主要污染物其等标污染负荷分别占所有农业面源等标污染总负荷的5026和4138COD只占836种植业源的TN和TP等标污染负荷量分别占所有农业面源等标污染负荷总量的3608和2171是区域内水体富营养化风险的主要构成因子也是农业面源污染防控的重点关键词农业面源污染现状调查等标污染负荷丹江口库区I
