Health risk assessment method and system for territorial space planning

The invention relates to a health risk assessment method and system for territorial space planning. The method comprises the steps of obtaining a spatial scale of an evaluation scheme; determining a grid unit for carrying out health risk assessment according to the spatial scale; acquiring health risk basic data; determining risk factor data and background factor data according to the health riskbasic data; performing health influence assignment on the risk factor data and the background factor data according to the grid units to obtain various risk factor influence analysis graphs and wind field simulation analysis graphs; performing spatial superposition analysis processing on the various risk factor influence analysis graphs and the wind field simulation analysis graph to obtain a health risk comprehensive analysis grid graph; and determining planning optimization suggestions according to the health risk comprehensive analysis grid map. The method can comprehensively evaluate the negative health influence
