Ant species diversity of Dongchuan dry-hot-valley,Kunming City
In order to clarify the ant diversity regularity in Dongchuan dry-hot-valley,Kunming City,and provide theoretical support for local vegetation restoration,the ant community was surveyed through the plot-sampling method.The results showed that 53 species belonging to 24 genera and 5 subfamilies of Formicidae were recognized in the 8 sample plots,of which Tetramorium wroughtonii(Forel)was the dominant species.Meanwhile,7 common species(occupying 13.21%of the total species),11 relatively common spe-cies(occupying 20.75%),21 relatively rare species(occupying 39.62%)and 13 rare species(occupying 24.53%)were observed.Main indexe of ant communities was shown that species number was from 5 to 22(average 12.8),individual density was from 4.8 to 147.2 head/m2(average 62.4 head/m2),diversity index was from 1.049 2 to 2.048 0(average 1.463 3),evenness index was from 0.505 8 to 0.708 6(average 0.595 4),and dominant index was from 0.209 1 to 0.486 6(average 0.347 2).Similarity coefficients be-tween ant communities from the 8 sample plots were 0.000 0~0.300 0,indicating that the similarity between the two different plots in the survey area was at the level of extremely dissimilar to moderately dissimilar.The ant species richness of Dongchuan dry-hot-valley was generally lower,and the combined effect of air temperature and humidity had important influence on vegetation,then influencing the main indexes of the ant community.
