摘要
在国内外研究成果基础上,总结了长江流域等重点区域的污染物输出系数,修正估算出西充河流域西充县境内的TN、TP的污染负荷。运用输出系数。区域非点源污染TN负荷为926.87t/a,TP为89.15t/a,其中农业人口污染、畜禽养殖污染和农田土地径流污染对非点源TN、TP贡献率较大,其中农业人口污染是TN和TP的主要污染源,且TN负荷量远大于TP负荷量。西充河流域西充县境内非点源污染要得到相应的重视,并加以治理。
Based on research results at home and abroad, the Yangtze River and other focal point of pollutants output factor are summed up. Xichong River West County section of TN, TP pollution load are estimated. The export coefficient model is used. TN regional non-point source pollution load of 926.87 t/a, TP was 89. 15 t/a, of which agricultural population of pollution, livestock and poultry breeding farm land runoff pollution and non-point source pollution on TN, TP larger contribution rate, of which agricul- tural population of pollution is the main source of TN and TP and TN load is much larger than TP load. Xichong River West County domestic non-point source pollution should getappropriate attention and proper treatment.
