FUNCTIONAL DIVERSITY AND ITS ATTRIBUTE FACTORS IN THE YUNMENG MOUNTAIN NATIONAL FOREST PARK IN BEIJING, CHINA

ABSTRACT The interaction of diversity with environmental gradients is an important topic in ecology. This study investigated the pattern of change in functional diversity in forest communities along an altitudinal gradient in Yunmeng Mountain National Forest Park, China. Forty-two quadrats measuring 10 x 10 m in the forest communities were set up along this altitudinal gradient; plant species, traits and environmental variables were measured and recorded. Six functional diversity indices, namely, Modified functional attribute diversity (MFAD), Functional diversity plot-based dendrogram index (FDp), Functional diversity community-based dendrogram index (FDc), Functional evenness (FEve), Functional divergence (FDiv) and Functional dispersion (FDis), were used to calculate functional diversity. The results showed that functional diversity varied greatly in forest communities in the Yunmeng Mountain Forest Park. Functional diversity was significantly correlated with elevation and slope position and somewhat correlated with soil depth. Functional diversity increased with an increase in the elevation and decreased as the slope position changed from valley bottom to hill ridge. Functional diversity was closely related to species richness. The six functional diversity indices were all applicable to functional diversity studies of forest communities.
