The invention provides an urban multi-scale wind environment numerical simulation method, which comprises the following steps of: generating a circular urban terrain model taking a city as a center, embedding an urban building group model into the urban terrain model through model inlaying, and establishing a wide-area urban overall model; extracting a wide-area city overall model by adopting Boolean subtraction operation, segmenting the wide-area city model in a form of a round outside and a square inside, and performing simulation; extracting an embedded local block model, performing interpolation on the boundary, and providing an accurate wind environment boundary condition for the local block model and performing simulation. According to the method, a nested model method is adopted, unreasonable inflow boundary assumption can be avoided in large-scale urban overall simulation, and a reasonable flow velocity boundary is provided for a local block model directly after urban macroscopic wind field simulation
