Health influence assessment method and system applied to urban planning scheme

The invention discloses a health influence assessment method and system applied to an urban planning scheme. The assessment method comprises the following steps: (1) spatial data and attribute data based on a current situation and the urban planning scheme; (2) calculating PM2.5 variation (delta Air) and physical activity variation (delta PA) of the current situation and the urban planning scheme scene relative to the current situation; (3) calculating the number change (H) of diseases/death caused by the urban planning scheme; and (4) an evaluator judges whether the planning scheme needs to be optimized or not according to the output of the step (3). The system comprises an index calculation module, a PM2.5/physical activity variation calculation module, a health result calculation module, a planning scheme optimization module and the like. A complete quantitative health influence assessment method is constructed based on an assessment path of construction environment-health risk/health behavior-health resul
