英文摘要：

This paper introduces how to set up CFD digital model of city. An accurate and reasonable CFD model is the key to study the relationship between urban planning and city climate. In order to transmit the complicated city into simulatable CFD model, it is necessary to transform the character of building material, digital model of water and characteristic of city into the parameters of CFD model and establish simulation boundary. Further more, the resuits of this method are analyzed and summarized.
