Correlations between vegetation properties and fitness of plateau zoker habitat

The study was that using population density of plateau zokor（Myospalax baileyi）on behalf of habitat suitability analyzed the correlations between vegetation properties, such as cover, height, aboveground biomass and plant diversity, and five gradients of population densities of plateau zokor. The results of this study showed that all of vegetation property indices had significant correlations with population densities. The vegetation cover and height showed extremely significant linear correlation with population densities, whereas the aboveground biomass and species diversity showed nonlinear correlation (unimodal curve). However, the vegetation height and aboveground biomass were often disturbed by uncertain enviromental factors, but the vegetation cover and species diversity were relatively stable. Therefore, the latter are more accurate in conjecturing the suitability of plateau zoker habitat and predicting the trend of population development.
