1) conservative grazing

适度放牧
2) optimum grazing rate

适宜放牧率
1.
Studies on optimum grazing rates in grasslands based on a multi-objectives weighting analysis;
基于多目标权重分析的草地适宜放牧率探讨
3) over-grazing

过度放牧
1.
This paper reviewed the related domestic and abroad research achievements and details about how human activities such as grassland reclamation, over-grazing, excessive digging resulted in grassland desertification.
综合了国内外的研究成果,详细说明了草原荒漠化的人为主要原因———开垦草原、过度放牧、滥采滥挖是如何导致草原荒漠化的。
4) grazing systems

放牧制度
1.
The response of the standing forages and nutrient dynamics of community to different grazing systems was studied on Stipa breviflora desert stepper.
在短花针茅荒漠草原,比较研究了不同放牧制度对群落现存量与营养物质动态的影响,结果表明,划区轮牧和对照区牧草现存量差异不明显,但高于自由放牧区。
2.
Through comparing effects between grazing systems and a feedlot system on the degenerated vegetation, the roles of rotational grazing system playing in vegetation recovery were investigated.
通过对比研究放牧制度及围栏封育对退化草地植被的影响,来探讨划区轮牧在退化草地植被恢复中的作用以及最优的放牧方式。
3.
A comparative study on plant importance values and community diversity under different grazing systems was conducted in desert steppe of Inner Mongolia Plateau.
在短花针茅荒漠草原,对比研究了不同放牧制度群落植物重要值和多样性,研究结果表明:划区轮牧和对照区重要值较高的植物为短花针茅、无芒隐子草、碱韭和糙隐子草,自由放牧区1年生植物重要值较高;2002年Shannon-Wiener、Simpson和Pielou群落多样性指数自由放牧区偏高于轮牧区,但从3种指数的影响因子重要值的分布上看,轮牧区主要分布在建群种和优势种上,自由放牧区分布在建群种、伴生种和1年生植物上,可以认为轮牧条件下群落环境更稳定。
5) Grazing intensity

放牧强度
1.

6) Grazing system

放牧制度
1.

2.
