摘要: 本文阐述了小哺乳动物群落和植物群落的演替关系;验证了动物群落对植物群落结构的非独立性假设。小哺乳动物群落种的多样性与植物群落的盖度和高度呈显著负相关,植物群落的演替引起小哺乳动物群落的相应演替。并通过加速次生植被演替进程的试验,调控了有害小哺乳动物群落,提出从生态演替规律出发,在退化严重的草地上,通过人的合理参与,协调动植物群落间的结构关系,以达到人类获取畜牧业最大持续生产量.最终使生物生产量得到永续利用的目的。

Abstract: We examined the successiVe relation between small mammal community and p|ant
comminity at Haibei Research Station of Alpine Meadow Ecosystem in September 1989.The species diversity of small mammal communities were related to degree of vegetative denseness,and showed siginificantly negative correlation with hight of plant and vegetative cover.Small mammal community changed with change of the construction of plant community,and its composition depended on construction of plant community.
Otherwise,Using the two treatments,one of which was seeding grass(Elymus nutans,E.sibircus)plus controlling pest of rodents treatment,another was singular controlling rodents pests treatment,we monitored the response of small mammal communnity,plant community to both treatments and recoverable degree ofdegenerative vegetation destroied by Myospalax baileyi and Ochotona curzoniae at the same area from 1988 to 1989.During two years,singular treatment of controlling rodent pests didn't have the vegetation recovered,composition of small mammal community was simplified.On seeding grass plus controlling pest treatment,composition of plant community shifted toward composition of nature vegetation,quality of grassland was improved,small mammal community also shift from Ochotona curzoniae+M.baileyi community to Microtus oeconmus +O.cansus community. Ecological strategy of rodent pests management was discussed.according to regulation bio—community succession,humanity coordinated the relation between small mammal community and plant community by effective means of grassland management so that degenerative vegetation was not only recovered in a short time ,but pest population was also under control in a long time.
