Abstract: The west part of Yunnan is situated in two regions within the oriental region in zoogeography,one is the south region of China,another the southwest region of China,The gamasid mite communities in different habitats and regions were studied by using polar ordination analysis in this paper,10 gamasid mite communities on small mammals in different habitats and regions were merged into four community types.These four types are the indoor type in the south region of China,the indoor type in the southwest region of China,the outdoor cultivated land type in the south region of China and the outdoor cultivated land type in the southwest region of China,The results showed that the differences of habitats and positions in zoogeography caused the differences of gamasid mite communities, and the influence of different habitats was the most prominent.
