摘要
试验研究结果证实放牧制度对短花针茅荒漠草原群落植物生长存在影响 ,放牧制度对植物生长速度的影响较大 ,且轮牧和禁牧区植物生长速度大于自由放牧区 ;而对株丛枝条数无显著影响 ,种群密度相对稳定 ;植物贮藏性碳水化合物含量轮牧区高于自由放牧区和禁牧区 。
It is demonstrated that the grazing systems have an effect on the growth of Stipa brevifloracommunity.The grazing systems have a great effect on plant growth rate,and the plants grow more rapidly under a rotational grazing and forbidden grazing area than that under a continuous grazing area,while they have no significant effects to the number of tillers under an individual plant.Plant population density is relatively steady.Plant carbohydrate content is higher under a rotational grazing area than that under a continuous grazing and forbidden grazing area in general,and the plant growth potential is the best on rotational grazing area.
