摘要
于2005-2007年对山西岚漪河岚县区段内的农业面源污染现状进行连续监测,并将农业面源产污划分为化肥施用、畜禽养殖、农村废弃物和生活废物等四大类。在此基础上,计算出2005-2007年岚漪河岚县段内农村废弃物年生产总量为(6125.2±246.2)t,生活废物年产量达(133.26±0.27)t,N、P的年排放量分别为(121045.7±3706.3)、(42962.4±1270.0)kg。分析表明:畜禽养殖和化肥施用是引起岚漪河N和P污染的主要原因。
The present situation of the agricultural non-point source(NPS)in Lanyi River of Lan County,Shanxi Province was investigated between 2005-2007.And the agricultural NPS was divided into four categories,the application of chemical fertilizers,the livestock and poultry raising,rural waste,and domestic wastewater.The annual average amount of the rural and the domestic waste was(6125.2±246.2)t and(133.26±0.27)t respectively during 2005 and 2007.The annual average amount of nitrogen and phosphorus emissions was(121045.7±3706.3)kg and(42962.4±1270.0)kg respectively.Analysis also shows that livestock and poultry raising and chemical fertilizers are the major causes of nitrogen and phosphorus pollution in Lanyi River.
