摘要
基于2008年农业统计数据,对苕溪流域所辖6个区县的水环境农业面源污染进行了分类调查,并采用等标污染负荷的评价方法对各类污染源进行评价。结果表明:2008年各农业非点源污染源流入苕溪流域水体的COD,TN和TP分别占总量的67.82%,28.75%和3.42%,等标污染负荷率COD,TN和TP分别为6.88%,58.37%和34.75%。就各农业非点源污染源来看,畜禽粪便污染源的等标排放量和污染负荷最大,成为威胁苕溪流域水体的最大污染源。
Comprehensive evaluation of agricultural non-point source pollution around six counties around Tiaoxi River was conducted by equal standard pollution loading method in 2008.The results indicated that the lose rates of COD,TN and TP were 67.82%,28.75% and 3.42%,respectively.The equivalent standard pollution loading rates of COD,TN and TP were 6.88%,58.3% and 34.75%,respectively.The equivalent standard pollution loading rates of animal and poultry feces,chemical fertilizer,breeding fish ponds,and domestic living sewage were 43.87%,23.95%,17.34% and 14.84%,respectively,which showed that the animals and poultry feces was the greatest agricultural non-point source of water system in Tiaoxi River drainage area.
