摘要
For the purpose of (1) investigating the relationship between urban planning and the atmospheric environment, and (2) improving the atmospheric environment through rational and scientific planning, an urban sub-domain scale model is developed in the form of a three-dimensional non-hydrostatic model with k - epsilon closure. The distribution and azimuth of buildings, the screening of shortwave radiation by buildings, and the underlying surface type as characteristics of the urban environment are included, the ground temperature is calculated using the force-restore method, and the concentration equation is solved simultaneously. The model is evaluated using special field observations and wind-tunnel experiment data, showing that model results meet the observational and experimental data generally well. Based on the model, an index system and evaluation method is set up to assess the impact of urban meteorology and the atmospheric environment using urban sub-domain planning. As an example, two layouts of a specific sub-domain in Beijing are assessed. The impact assessment system of urban meteorology and the atmospheric environment using urban sub-domain planning, which includes the urban sub-domain scale numerical model, index system and evaluation method, provides an effective approach to improve the atmospheric environment through rational and scientific planning.
