Based on the numerical simulation in this paper, the local climate of the Majianglong traditional villages in the Lily Town city is analyzed, the influence of the village layout in the traditional villages on the wind environment and the adaptability of Lingnan traditional village layout to the regional climate is studied. The layout characteristics of Majianglong traditional village is the former pond after the village and comb layout. The results show that the traditional grid layout of MajiangLong village obviously influence the microclimate of residential street. The traditional grid layout and relative position of residential plays an important role to the micro-environment of indoor and courtyard. In summer, the area close to the entrance of the cold lane and the edge of residential buildings is a more comfortable wind environment. However, the residential space in the middle of traditional building layout maintains a better thermal comfort environment because of the isolation of street space.
