放牧强度是一种草地变化的重要驱动因子,直接或间接地影响着草地生态系统的草地群落特征、多样性、群落结构、土壤的物理化学性质和家畜生产性能等变量,文章就放牧强度与草、土、畜的研究进展做了综述和总结。大多数是在探讨草地中的变量与放牧强度的关系,即沿着放牧强度梯度有何变化规律。许多研究给出了不完全相同的结论,但多数研究认为适度放牧有利于草地生态系统的植被、土壤和家畜的可持续发展。放牧强度应在季节上进行调整,以使草地能够得到可持续利用。
Grazing intensity is an important driving force of grassland change, which directly or indirectly affects the grassland ecosystem characteristics of grassland community, diversity, community structure, soil physicochemical properties and livestock performance and other variables. , Soil, livestock research progress made a summary and summary. Most of them are discussing the relationship between grassland variables and grazing intensity, that is, how the grazing intensity gradients change. Many studies give different conclusions, but most studies suggest that moderate grazing is beneficial to the sustainable development of vegetation, soil and livestock in grassland ecosystems. Grazing intensity should be adjusted seasonally so that grasslands can be used sustainably.
