摘要
放牧是草地利用的主要方式。在放牧过程中,牲畜通过采食、排泄和践踏等方式直接或间接地影响草地土壤种子库,土壤种子库和植物群落间的关系也因此会发生变化。本文主要从放牧对土壤种子库规模、物种组成、空间分布格局及土壤种子库和植物群落间的互作关系4个方面做了归纳总结,旨在为草地生态系统的可持续利用和管理提供理论依据。
Grazing is an important way for grassland utilization. Livestock has direct and indirect impacts on soil seed bank through feeding,excretion and trampling during the grazing process which change the relationship between soil seed bank and plant community. In the present paper,we summarized the effects of grazing on size,species composition,spatial distribution pattern of soil seed bank and its relationship with plant community to provide a theoretical basis for sustainable utilization and management of grassland,and promote the further researches of grazing impacts on grassland.
