Based on statistical data of livestock and poultry breeding in Guangzhou City,livestock and poultry pollutant and its spatial distribution characteristics were estimated by adopting emission factor and chorisogram method.The environmental impacts of livestock and poultry pollutant on water body were also studied.The results are as follows.(1) The livestock and poultry farms of Guangzhou presented obvious circling structure and orbicular distribution around the center of Guangzhou,and the major distribution regions located in the suburb districts.(2)The total pollutant amount from livestock and poultry breeding in Guangzhou was large especially circling in suburban regions.(3)The water quality of water sources such as Liuxihe River,Dongjiang River,Zengjiang River and Pearl River West Channel etc.,was seriously affected by livestock and poultry pollutant input.According to the current situation and spatial distribution of livestock and poultry breeding of Guangzhou,pollutant prevention measures and sustainable development policies were proposed,which could be benefit to pollutant prevention and environment management of livestock and poultry breeding.Furthermore,it also provides reference for regional livestock and poultry production sustainable development research.
