During May (beginning of rainy season) and September (late rainy season) of 2003, we collected ants by trapping in five karst habitats in Shilin Park, Yunnan: Cyclobalanopsis glaucoides forest representing the original subtropical karst plateau monsoon zonal vegetation, secondary forest, brush, grassland, and Pinus yunnanensis forest representing the secondary-succession karst vegetation. The community composition and diversity of ants, and community similarity were studied, and cluster analysis was conducted. All 8775 ants from the five habitats were grouped into 4 subfamilies, 16 genera and 26 species. The dominant species are Kartidris ashima, Pseudolasius bournica, and Campontus chongqingensis. The lowest diversity index was found in the Cyclobalanopsis glaucoides forest, and the highest in brush and the Pinus yunnanensis forest. The similarity index of all communities fell between 0–0.2609. The results showed that ant diversity was affected by environmental factors, and significant differences occurred among ant communities in secondary habitats in karst zonal vegetation created by human disturbance.
