中文摘要	herbivory and burrowing activity of mammals may influence the species composition and diversity of plant communities. the effect of corridors and holes systems constructed by root vole (microtus oeconomus pallas) on the plant species diversity was studied in the habitat of high - mountain meadow (3250 in a.s.l in qinghai-tibet plateau, china). by using grid method, these disturbances were studied on 16 plots (100 cm x 100 cm) distributed in 4 transects in studied area, in august 2000 and 2001. the disturbance intensity index, d, was calculated as the percent of the ground surface disturbed by voles in the study area. plant species were identified and counted on the same plots. in total 46 plant species were identified - 39% of this number was considered as sensitive to the vole disturbances as their occurrence and/or abundance decreased along the disturbance intensity. generally, a significantly negative correlation (r = - 0.911 p < 0.01) between vole aboveground disturbances and plant species diversity (h') was found. the results suggest that root vole ground disturbances, especially in the form of actively utilized holes and corridors have significantly negative influence on plant species diversity in high-mountain grassland habitat.
