| 中文摘要 | this research was conducted on alpine meadow site at menyuan county, qinghai province, people's republic of china to determine the effects of native, subterranean rodent of qinghai-tibet grasslands, the plateau zokors (myospalax baileyi), on seasonal above-and below-ground plant biomass, plant species diversity and productivity. both total peaks of above-and below-ground biomass were the greatest (413.600 g/m~2 and 2297.502 g/m~2) in the patch no any plateau zokors colonized by plateau zokors over 10 years in august and october, respectively. both above-and below-ground biomass were significantly increased in the patches where plateau zokors were removed or the burrow systems were abandoned for five years compared to the patches plateau zokors colonized over 10 years. however, both above-and below-ground biomass in abandoned patches were significantly lower than that in uncolonized patches. monocotyledonous biomass was reduced greatly, but the non-palatable dicots were significantly increased in colonized patches. the palatable biomass of monocots and dicots were increased in abandoned patches. total plant species diversity was the greatest in uncolonized patchesand least in abandoned patch. the total net primary production in colonized patches was reduced by 68.98% compared with uncolonized patches. although the patches were without any plateau zokors disturbance for fives years, the total net primary production just reached 58.69% of the uncolonized patches. the above-ground net primary production in abandoned patches increased 28.74% and the below-ground increased 54.91% compared with the colonized patches. we suggest that plateau zokor-induced changes in plant above- and below-ground biomass and species diversity may lead to further alterations of nutrient cycling and trophic dynamics in this alpine meadow ecosystem. |
