Abstract In this paper, Levins formula and the formula determined by Pianka get state Kong Dragon Nature Reserve, Guangxi, Sterculia Community main populations, communities selected 10 major species of tree layer and shrub layer were 10 major population niche breadth and niche overlap calculated , and the main population niche breadth and niche overlap relationship were discussed. The results showed that: the shrub layer, the important value of saplings Sterculia 249.28 percent, followed by sour Dominant species is an important sub-saplings 194.33%, a difference of not too great, the advantages of population is not obvious, in the niche width, but also sour child with Sterculia account for a large value, respectively, 9.9655 and 7.9566, flag leaf and the South Grand Dracaena cattle Niche for 1.9629 and 1.9499. The maximum niche overlap occurred in the flag leaf and Hainan Dracaena Hydnocarpus was 0.2016 between the overlap value is small crack in cut flowers and long PDB Stephen Long candles, the is 0.0009; in the tree layer, the Sterculia important value of 274.70 percent, followed by students are an important dominant species of Ficus more than double the value, the larger the niche breadth of 8.4401 and intercept Sterculia discolor Tree by 5.3598 crack, overlap occurred in the largest apple and fig bean pieces to 0.2074 between Guangxi, Guangxi smaller pieces of wood between the bean and tea bar, the overlap is 0.0052. Overall, the important value of a large dominant population niche width is usually larger, dominant species overlap is universal, the advantages of a large niche breadth niche overlap populations are usually large, but Dan Shansheng high habitat heterogeneity also allows smaller niche breadth between species pairs have a greater niche overlap.
