Total quantity control is an important means and measure of protecting the quality of the air and environment.
Generally speaking, the existing calculation of the total quantity in environmental control is discussed under assumptions
in the closed system. This is largely inconsistent with the practical facts. In this paper, the region is regarded as an open
environment system, Datong Economic Development Zone is taken as the background, and the quality control of the air
and environment is taken as the objective. Next, the concentration contribution curve and distribution function of the
dispersal of air pollution sources are analyzed, the share and proportion of contribution of the interior and exterior
pollution sources of the development zone are calculated. An optimization model of the total pollutant discharge is
constructed, and the total quantity of pollutant discharged by the development zone is measured, calculated and analyzed.
