The invention is suitable for the technical field of city planning, and provides a design method and
system for
smart city planning, and the method comprises the following steps: calling city road network information and service facility information, the service facility information comprises a plurality of service facilities, and each service facility corresponds to a
facility type, a service coordinate and service energy efficiency; calculating the energy efficiency cardinal number of each living area, calling the
population number of each living area, and calculating the
per capita energy efficiency value; and determining
facility planning information based on the position of each living area, the
per capita energy efficiency value and the
facility type, wherein the
facility planning information comprises the
facility type, the planning position and the service energy efficiency. According to the method, the energy efficiency cardinal number of each living area is calculated by integrating the weight of the service facility, the service energy efficiency, the distance
attenuation coefficient and the
path distance, and the service facility supply level of each area can be accurately reflected. By calculating the
per capita energy efficiency value, the supply and demand matching degrees of service facilities in different areas can be visually compared, and data support is provided for facility supplementation.
