20名体育学院健康男生随机分为两组(吸氧组和对照组) ，实验要求全体受试者完成一次性递增负荷运动，运动至力竭，观察运动即刻和恢复期各指标的变化情况。 - 2 the productive afforestation during timber production period from medium 1960 s to 1970 s and the continually protective afforestation after the setting up of the nature reserve were the primary causes of the significant variation for vegetation distribution pattern along topographic gradients during the study period . furthermore , natural recovery process also gave an impulse to the pattern changing . some obvious phenomena of human impact on natural vegetation can also be watched in our working area . decreasing of coniferous forest and broad - leaved forest with the simultaneous increasing of shrub reflected the type and spatial characteristics of human disturbance activities in working area . the related management department should consider the above problems more seriously
结果表明： 1 20世纪60年代中期大规模森林砍伐活动使林地的分布格局受到强烈干扰，这种影响一直延续到80年代中期2研究时段内的生产性育林活动保护性育林活动和自然植被恢复过程，对森林植被类型的地形分布格局产生了显著的影响3保护区目前仍存在着一些显著的人为干扰现象，针叶林及阔叶林比重的减少和灌丛数量的相应增加，反映出保护区目前人为干扰活动的主要类型和空间分布特征，应当引起管理部门的足够重视。
