With the improvement of living standards, peasants have attached increasing attention to quality of living environment, indoor thermal comfort of rural residence has become a functional need of new countryside residence. Chengdu is a foggy area with shorter sunshine hours, humid air, more foggy but fewer windy days, so local residence is likely to be muggy, which influences comfort of residents seriously. According to relevant researches, most rural residences in Chengdu use only natural ventilation, and the indoor thermal comfort is poor. In view of this, this paper tried to improve indoor thermal comfort and quality of living environment from the perspective of residence functional design.
According to the plant information of Puxing Village, a typical village in Chengdu Plain, the GIS map was drawn to analyze the landscape ecology pattern by FRAGSTATS software. The results show that in the past 10 years, although urbanization had a great impact on the rural ecological pattern, it was still in a stable ecological environment. The comparison of the landscape index shows that the replacement of the vegetation community pattern leads to the conversion of the source population from the original farmland to laurel, and the increase of whole vegetation community under artificial intervention is the most important factor for the change of the vegetation community richness. At the same time, the pattern analysis at the horizontal level also reveals the obvious effect of the fast road as an artificial product for the enhancement of nearby vegetation community richness.
