摘　　要：结合前人对天然草地载畜量的研究,在草畜优化条件下,归纳总结出"生态载畜量"这一新的测算方法来适应生产发展的需要。在农牧民经济发展和保护草原生态环境之间找到一个草地载畜量平衡点。新的测算方法为草地畜牧业可持续发展提供了理论依据。Based on the previous research, a new method of calculating pasture ecological livestock capability was proposed on the grass-livestock balance in order to meet the requirements of development. New method finds out a balance between increasing herder income and protecting ecological environment on grasslands, and ensures the sustainable development of grassland animal husbandry.
