Abstract: To reveal ant diversity of southwestern Yunnan , ant communities of Nangun River Nature Reserve were surveyed by using sample-plot and search-collection methods .Totally 188 species belonging to 11 subfamilies and 57 generas of Formicidae were collected in 16 sample plots .The results showed that main indexes of ant communi-ties in different sample plots were as follow:5~72 of species numbers , 12.5~1 234.0 heads/m2 of individual densities , 0.088 7~0.702 4 of predominant indexes , 0.797 8~2.935 5 of diversity indexes , 0.251 4~0.717 0 of evenness indexes .Valley rainforest had the maximum ant species number , while mossy evergreen broad -leaf forest had the minimum ant species number .Rubber tree forest had the highest individual density , while mossy evergreen broad-leaf forest had the lowest individual density .Mountain rainforest had the maximum diversity index and evenness index and the minimum predominant index , while teak forest had the minimum diversity index and evenness index , and the maximum predominant index .Monsoon evergreen broad-leaf forest and valley rainforest were rich in rare species and were valuable for taking conservation action .Mountain rainforest, semi-evergreen monsoon forest , mossy evergreen broad-leaf forest and mixed conifer&broad-leaf forest had a number of rare spe-cies with higher conservation value .Similarity coefficients indicated that ant communities of different vegetation types had significant difference .
