Abstract: In the last eight years,the production of livestock in Jiangsu Province has been increased gradually.Based on the investigation data of 1997-2004,and according to the discharge rate of various livestock,this paper calculated the fecal pollution of livestock and its pollution load from 1997 to 2004.The result showed that the fecal amount of livestock was increased significantly,and the fecal pollution load had been increased from 12.5 t/ha in 1997 to 14.9 t/ha in 2004.Meanwhile,the higher fecal pollution load was mainly distributed along the coast and the Changjiang(Yangtse) River,which has already been exceeded the critical value.The results indicated that the fecal pollution of livestock in Jiangsu Province became a serious problem.Therefore,it is urgently needed to strengthen prevention and control of the feces pollution from livestock.
