Abstract:

In order to provide basic information for the further in-depth reveal of the features on Karst biodiversity and its functions, the field investigation and the indoor isolation experiments and identification analysis on the soil animal functional groups in Guizhou Karst plateau valley rocky desertification area had been carried out afterwards in August 2010. The results showed that: the soil animals of this study area could be divided into four different functional groups, that was, rot feeding, herbivorous, predatory and omnivorous soil animals, of which the individual number of omnivorous soil animals took the largest ratio of the total catch, whereas, the predatory the smallest. From the horizontal distribution point of view, differences of the individual number of the soil animals were significant, while the group number was much more uniform. The vertical distribution point of view, the patterns of the soil animals of various study plots all had shown the apparent table-together phenomenon. Thus, the further in-depth reveal of the features on Karst biodiversity and its functions could be concluded as: the functional group diversity indexes of the soil animals of various plots were significantly different. The unique groups of various plots reflected the particularity of the each local environment. And the above two features were indicative of the ecosystem.
