Abstract: At present, poultry and pigs were the main livestock breeds in Wuhan, and all large-scale farms were located in the new urban area. The density of livestock and poultry farms, the amount of breeding and nitrogen load of farmland in each administrative region of Wuhan city were analyzed. Three high-density breeding areas, Jiangxia, Xinzhou and Huangpi, were selected, and the area with the most intensive nitrogen emission was selected by taking the street as the unit. It included Wulongquan street, shanpo street and Zhengdian street in Jiangxia district, Liji street, Sandian street, Wangji street and Fenghuang street in Xinzhou district, and Liji street, Mulan township and Liuzhi street in Huangpi district. Finally, considering the actual planting situation of main crops in Wuhan city, it was determined that rice was the more suitable crop variety planted by manure.
