Abstract: For the purpose of exploring the spatial distribution pattern and the causations of green peafowl(Pavo muticus), the authors took the green peafowl in Mojiawan, Konglonghe Natural Reserve, Chuxiong, Yunnan Province as a subject of the study, 36 foraging plots and 16 roosting sites were set up, an equal number of available plots corresponding to forging plots and roosting plots were also set up respectively. There were 21 identical environmental factors of each compared sample plot were all observed, and the differences among the various environmental features as well as their overall impacts on the habitat selection of green peafowl were comparatively analyzed. Research results showed that food and shelter conditions are factors influencing the feeding site selection of green peafowl. Green peafowl tend to select the sunny slopes spread along the valleys, the slope gradient of which is smaller than that of compared sample plots. Green peafowl often forage close to water sources and paths, where there are more varieties of trees and more lianas with taller trees, at same time coverage of trees and diameter at breast height is the main factors affecting the roosting site selection of green peafowl. In addition green peafowl prefer to choose the tall forest types with high shade degree as roosting sites. DCCA analysis results showed that the habitat selection of green peafowl has a multidimensional interaction with the environmental factors, and that there exists differentiation between their foraging plots and their roosting sites in environmental characteristics, and that the vertical migration pattern of daily activity has been displayed. The spatial distribution of green peafowl in the direction of latitude—altitude is more concentrated, which is shown by the accumulative distribution in the areas with good concealment conditions and abundant food and water resources.
