Abstract: In this study, six different types of residential areas in Guiyang were selected as the research objects, including high-rise high-density, high-rise low-density, middle-rise high-density, middle-rise low-density, low-rise high-density and low-rise low-density. The indices of sunshine compliance rate and the building's sunshine hour ratio were constructed to compare and analyze sunshine environment across those six different residential areas. The factors influencing sunshine environment in different residential areas were studied. The results showed that the average sunshine compliance rates of the six types of residential areas were 36.9%, 61.9%, 20.6%, 69.6%, 26.5% and 45.0%, respectively. The average sunshine compliance rate of low-density residential areas was 2.25 times higher than that of high-density residential areas within the same type, among which the sunshine environment of low-density residential areas was better. The sunshine environment of different types of low-density residential areas was different. The sunshine hours for high-rise low-density and middle-rise low-density forms were concentrated in 5-6 hours, while the building's sunshine hour ratio was 0.24 and 0.32, respectively. The sunshine hours for low-rise low-density forms were mainly 6-7 hours, with a building's sunshine hour ratio of 0.28. Compared with other types of residential areas, the low-rise low-density type of sunlight environment was the best. The plot ratio was significantly positively correlated with the building's sunlight ratio of 0-1 h sunlight hours in the residential area.

Key words: community form, sunshine analysis, sunshine hours, plot ratio, Guiyang City.
