Abstract: To understand potential environment pollution from livestock and poultry breeding in Anhui Province during the recent ten years, this paper studied spatial and temporal characteristics of environmental risks from livestock and poultry breeding in Anhui Province from 2004 to 2013 based on statistical data of livestock and poultry breeding and farmland area in Anhui Province. Results show that there is a great difference between livestock manure nitrogen load of farmland and livestock manure phosphorus load of farmland. Most of the countryside of Anhui Province belongs to no environmental risk area. High environmental risk is mainly in the municipal districts of Hefei City, Feixi County, Changfeng County and so on. Low environmental risk is mainly in Lingbi County, Quanjiao County and so on. In addition, the largest number of counties in Anhui Province belonging to environmental risk region is in 2005 (28 counties). In 2006 and 2013, there are 26 counties belonging to environmental risk region. The lowest number of the counties in Anhui Province belonging to environmental risk region is in 2007 (11 counties). This study could provide scientific basis for sustainable and healthy development of livestock and poultry breeding.
