Livestock and poultry excrement area bearing capacity accounting method and device based on water environment capacity

The invention discloses a livestock and poultry excrement area bearing capacity accounting method and device based on the water environment capacity. The method comprises the steps that A, the available water environment capacity of livestock and poultry breeding water in an area is determined; b, determining the average emission coefficient of live pig pollutants in unit equivalent; and C, according to the available water environment capacity of the livestock breeding water in the region and the average emission coefficient of the live pig pollutants in unit equivalent, determining the environmental bearing capacity of the livestock in the region. According to the livestock and poultry excrement area bearing capacity accounting method and device based on the water environment capacity, the area environment bearing capacity is calculated according to the livestock and poultry breeding available water environment capacity and the excrement nitrogen and phosphorus emission coefficients, the accounting model and
