Abstract: The paper deals with the relation between the slmeies diversity of small mammal communities and the diversity,height, coverage of plant communities. The structure and spatial pattern of small mammal communities and interspecific relationship on the four habitats (artificial grassland, half-artificial grassland, secondary grassland.derelict land) were studied at the area of Haibei Reserch station of Alpine Meadow Ecosystern in Sep.1989. Population densitits of animals were calculated by mounds coefficient for Myospatax baileyi，hole coefficiant for Ochotona curzoniae and removal sampling for other animals．The results were as follows: 1.four types of small mammal communities on the four habitats were determind: A.Microtus oeconomus +Myospalax baileyi community. B.Microtus oeconomus +ochotona cansus community. C.Ochotona curzoniae + Myospalax baileyi community. D.Cricetulus longicaudatus + Ochotona curzoniae community. These four communities distribute artificial grassland(Elymus nutans community), half-artificial grassland(Elymus mutans+ E.sibicus community), secondary grassland (potentilla anserina+ Ajania tenuifolia community) and derelict land (Aconitum gyman-andrum+Polygonum sibiricum community) respectively. 2. There is no linear correlation between the species diversity indexes of small mammals and of plants, but the species diversity indexes of small mammals are negative correlated significantly with the height and coverage of plants. 3.Myospalax baileyi is a eurytopic species. .Microtus oeconomus and ochotona cansus are mainly distributed the habitats with close vegetation, .Ochotona curzoniae and Cricetulus longicaudatus are mainly distributed the habitats with short or sparse vegetation. these results demonstrated that the composition of grassland small mammal communities was determined primarily by vegetation struture.
