Abstract: Global climate change has led to continuous warming and the frequent occurrence of extreme weather events, posing serious challenges to the human settlements. Traditional settlements, as forms of habitat that have undergone natural selection and evolution, have formed a series of unique architectural patterns adapted to the local climate. Therefore, in-depth research on the conservation and planning of traditional settlements, especially on the mechanism of their arbor space's effect on microclimate, is crucial for exploring the theory and methods of climate adaptation for energy conservation in the region, as well as for improving the comfort of future habitat construction. Based on field investigation and numerical simulation, the microclimate of farmhouse forest and its derived models in western Sichuan was simulated, focusing on the spatial distribution characteristics and trends of meteorological parameters such as air temperature, relative humidity, wind speed and direction, and thermal comfort, aiming at analyzing the mechanism of the spatial patterns and configurations of arboriculture on the microclimate of colony environments, and exploring the nature-based climate adaptability solutions. It was found that with the increase of arbor coverage, the more significant the cooling and humidifying effect is inside the farmhouse forest, but it has a limiting effect on air flow, which leads to local heat wave effect and discomfort. In addition, the number and layout of trees also had a strong regulatory effect on climate resilience, blocking the entry of external thermal air and providing comfort when distributed upwind of the farmhouse forest, but potentially restricting air flow and increasing internal thermal sensations when distributed downwind of the farmhouse forest.
