中文摘要	Yabello牧场是埃塞俄比亚博拉纳的一个半干旱地区的牧场,目前面临着草场退化的严重挑战。植被覆盖的变化、过度放牧和季节性变化极大地影响了Yabello牧场的牧草组成和生物量。本文评估了植被覆盖、放牧和季节对Yabello牧场的牧草组成和生物量的影响。首先采用1m*1m的随机样方进行实验,根据植被覆盖类型和放牧变化选择样点,并对季节影响进行评估。使用SAS统计软件和Microsoft Excel分析牧草组成、牧草高度和质量数据。本研究总共记录了26种草种,其中Chloris roxburghiana,Chrysopogon aucheri和Chrysopogon aucheri草种均表现出最高的平均单种覆盖高度和生物量产量。因此,建议将这些草种用于研究区域退化草地的恢复。研究结果还表明,植被覆盖类型、放牧和季节变化是决定牧草种类组成、牧草高度和生物量产量的关键因素。最后,研究结论还认为控制灌木丛植被并平衡放牧水平的可持续管理对于该地区的可持续牧草生产和生物多样性保护至关重要。
英文摘要	The Yabello rangeland is a semi-arid area in Borana,Ethiopia that is facing great degradation challenges.Increasing infestation of vegetation cover,over grazing and high seasonal variation have significantly affected the herbage composition and biomass in the Yabello rangeland.This study focused on assessing the effect of vegetation cover,grazing and season on both herbage composition and biomass in the Yabello rangeland.An experiment was conducted using randomized plots of 1 m*1 m.Sites were selected based on vegetation cover type and grazing variation,and seasonal impacts were also assessed.Data on herbage composition,height and mass with respect to those parameters were analyzed using SAS statistical software version 9.1 (SAS Institute,2001) and Microsoft Excel.A total of 26 grass species were recorded and Chloris roxburghiana Chrysopogon aucheri and Chrysopogon aucheri grass species showed the highest average single species cover height and biomass production,for all the sites among all parameters.As a result,those grass species are highly recommended for the rehabilitation of degraded rangeland in the study area.This study also showed that vegetation cover type grazing and seasonal variation were the key factors in determining herbage species composition,height and biomass production.Finally,we recommended that sustainable management which controls bush vegetation cover and balances grazing levels is essential for sustainable herbage production and biodiversity conservation in the area.
