Abstract:

The surface cover and soil hydrological characteristics of three alpine shrubs in eastern Qilian Mountains were studied in the report. The experimental alpine shrubs are Potentilla fruticosa shrub,Salix spp. shrub and Rhododendron spp. shrub. The result showed that the different shrub had significant effect on water holding capacity of surface cover and soil; The cumulation of litters was Salix spp. shrub> Potentilla fruticosa shrub > Rhododendron spp. shrub; The litter accumulation exhibited was Rhododendron spp. shrub > Salix spp. shrub > Potentilla fruticosa shrub; The water holding capacity of litters was Potentilla fruticosa shrub >Salix spp. shrub > Rhododendron spp.shrub; The water holding capacity of moss was Rhododendron spp. shrub> Salix spp. Shrub >Potentilla fruticosa shrub; The maximum and minimum water holding capacity、the capillary water holding capacity of soil in different shrub types were all Rhododendron spp. shrub > Salix spp. shrub > Potentilla fruticosa shrub;The soil infiltration rate of three alpine shrubs was basically identical, and the soil infiltration all gradually decreased with the infiltration time expand.

Key words: litters, moss, water holding capacity, soil infiltration, alpine shrub
