【摘要】：基于牦牛所处地理环境,即青藏高原的特殊性,以及牦牛放牧这一生产方式在该地区第一产业中的重要地位,国内外学者从牦牛放牧系统的管理出发,对该系统中各因子之间的相互响应进行了研究,主要包括当放牧制度不同时,系统中的初级生产力和次级生产力的表现特征。从不同放牧制度中草地和家畜的特征表现,再到人为管理对这两种生产力的影响,研究者通过对比和试验进行了系统优化方法的探索。笔者通过对现阶段已有的研究成果进行整理和分析,概括在不同的放牧管理方式下草地放牧系统中的牦牛在生产力水平方面的差异,以及草地对不同放牧强度的响应,探究青藏高原地区牦牛放牧方式如何影响草畜之间的互作关系。在此基础上,分析其在实际生产活动中存在的问题,以及如何通过改进管理制度优化生产的办法,并对牦牛放牧系统发展进行了展望。
[Abstract]:Based on the geographical environment of yak, that is, the particularity of Qinghai-Tibet Plateau, and the important position of yak grazing mode in the primary industry of this area, scholars at home and abroad set out from the management of yak grazing system. The responses of various factors in the system are studied, including the characteristics of primary productivity and secondary productivity in the system when the grazing system is different. From the characteristics of grassland and livestock in different grazing systems to the effects of artificial management on these two kinds of productivity, the researchers carried out a systematic optimization method by comparing and experimenting. The author summarized the difference of yak productivity level and the response of grassland to different grazing intensity under different grazing management methods by sorting out and analyzing the existing research results at the present stage. To explore how the grazing mode of yak in Qinghai-Xizang Plateau affects the interaction between grass and livestock. On this basis, the problems existing in the actual production activities are analyzed, and how to optimize the production by improving the management system is analyzed, and the development of the yak grazing system is prospected.
