Embodiment Construction
[0050] The present invention is described in further detail now in conjunction with accompanying drawing.
[0051] The most important work of the present invention comprises three parts:
[0052] 1) Based on the EPIC model, improve the ammonia emission from farmland fertilization, develop an advanced agricultural pollution source emission information processing system with Chinese characteristics, and establish the latest agricultural source pollutant discharge inventory;
[0053] 2) Establish an air quality simulation and forecast model that considers the impact of agricultural ammonia, and continuously improve PM 2.5 level of simulation and forecasting;
[0054] 3) Calculate the contribution of agricultural emission sources to PM in major agricultural areas in my country 2.5 contribution and put forward corresponding control countermeasures.
[0055] Such as figure 1 The shown air quality simulation and analysis system considering agricultural ammonia emissions, the simu...
