中文摘要：
放牧作为草地生态系统最主要的利用方式已经带来了很多不可逆的严重问题，为了缓解和改变这种现状，我国很多学者就放牧强度带来的影响做了详细的研究。研究发现，放牧强度对草地地下生物量的影响主要表现在地下生物量地下分布规律、地上地下生物量动态变化规律的改变，以及逆行演替后土壤含水量及其容重对草地生产力的作用。因此只有通过适度调整放牧强度才能最大化改善草地，并能获得一定经济和生态效益，促进区域的可持续发展。
英文摘要：
Grazing as a main use of the grassland ecosystem has brought a lot of serious irreversible problems, in which many scholars have made detailed study of grazing impact strength to alleviate and change this situation. The study found that the impact of grazing intensity on grassland underground biomass occurred mainly in below-ground biomass underground distribution law, the change of the dynamic variation of above and below ground biomass, and soil moisture in retrograde succession after their bulk density of grassland productivity. Therefore, only by moderating change grazing intensity can grasslands be maximally improved, and certain economic and ecological benefits, promoting the sustainable development of the region.
