Abstract: Based on investigations of rural population,size of livestock,amount of farm fertilizer and aquatic products,and pollution coefficients of production and emissions from the first China Pollution Source Census,the current status of water pollution from agricultural non-point sources in Nansi Lake basin in Shandong Province was estimated for 2009.The results showed that the total amounts of CODCr,TN and TP discharged from rural life,farm fertilizer,livestock and aquiculture were 192,278.71,103,126.04 and 6,990.82 t,respectively in Nansi Lake basin.CODCr was mainly from rural life,which accounted for 56.44% of total CODCr.TN was mainly from agricultural fertilizers,which accounted for 48.37% of total TN pollution.Rural life and livestock were also big contributors to TN pollution.Livestock was a major source of TP,accounting for 65.06% of the total TP pollution.The pollution from aquaculture was relatively low,but its effects should not be ignored.
