环青海湖地区天然草场牦牛的环境容纳量

摘要

由于长期过牧所造成的环青海湖地区天然草场退化一直是一个困扰该地区牦牛业可持续发展的重要因素。本研究通过对该地区草原生产系统蛋白质平衡进行研究，获得了该地区生态系统中牦牛的精确合理的环境容纳量。%Owing to the long term of over-grazing，the deterioration of rangelands have been a serious problem to sustainable development of yak production.This is due to the lack of scientific direction of carrying capacity of yak in rangelands.This study gained the accurate and justifiable value of carrying capacity of yak in surrounding Qinghai Lake area ecosystem by using the method of protein balance of production system.
