摘要
畜草平衡是牧场管理的核心和理论基础，在草地放牧生态系统中，草与畜之间相互影响，相互制约，载畜率的调控是实现畜草平衡的有力技术手段，载畜率的研究促进了草地学和畜牧学的结合，发展了放牧生态学。本文从理论和实践的结合上分析了载畜率与牧草生产、草地土壤、家畜营养、草地畜产品输出以及草地管理措施的关系，探讨了提高载畜率经济效益的途径以及最佳载畜率估测和最小财务风险放牧经营；论述了牧场对载畜率缓冲性和载畜率对保持牧场生态平衡的重要性。
This paper described the principles of stocking rate adjustment both in grazing ecology and pasture management. The relationships between stocking rate and pasture, stock-ing rate and soil properies, stocking rate and animal nutrition, and quantifying animal outputin relation to stocking rate , economic responses to increasing steeking rate were discussed.The pasture resilience and the importance of stocking rate in pasture ecosys-tem were presented in this paper.
