Abstract: Plots investigation based on evergreen broadleave forest in Fengyangshan Nature Reserve, we used the method of quantitative analysis to measure the niche breadths, niche similarity and niche overlap of ten dominant tree species. The results showed that: (1)The niche breadths were measured by Levins and ShannonWiener index respectively, there were many differences between the results, but the largest niche breadth of them was Schima superba, the value of B(L)i and B(sw)i were 0.771 and 1.325 respectively. (2)The niche similarities among the dominant species were very big, this showed that they had high similarity in using the resources. There was no obvious correlation between niche similarity and niche breadths. (3)The niche overlap among the dominant species were very big, and the values of Lih and Lhi were almost the same, this fully showed that dominant species had similar ecological characteristics. If the niche similarity was big the niche overlap was big, so did the opposite.
