中文摘要	低覆盖度行带式固沙林具有显菩的防风固沙效果,已经在我国的半干旱地区广泛推广.针对内蒙古自治区呼和浩特市和林格尔县不同配置的柠条锦鸡儿人工林,进一步研究不同带间宽度带内植被自然恢复过程及物种多样性的差异,结果表明:(1)在覆盖度为20%左右时,合理的行带式格局分布的柠条锦鸡儿人工林带间植被的恢复效果优于随机分布格局的样地.(2)柠条行带式造林不宜太窄和盖度太大,会影响其林下物种丰富度.(3)宽的带间距带内物种丰富度与物种多样性和均匀度以及其生物量变化曲线呈现了两个高峰,出现在距柠条带6-8m左右,而窄的带间距带内只有一个高峰.因此,该地区柠条带宽度为12m-16m可以使其带内的草本物种多样性和生物量达到最大.
英文摘要	The low vegetation coverage band model of sand fixing forest has remarkble effects on the windbreak and shifting sand fixation, and has been popularized in semiarid areas of China. In order to discuss the change and recovery rule of the plant along with the distance from the Caragana korshinskii forest belts, the different distance schemes from the Caragana korshinskii forest belts were researched in Helingeer, Huhhot, Inner Mongolia. The research showed that: (1) when vegetation cover was about 20%, the effect of the rational belt scheme forest on vegetation recovery was better than that of random plot. (2) The afforestation of Caragana korshinskii forest shouldnt wider or with bigger coverage for its influence on the species abundance. (3) In the wide spacing forest, there were two peaks in all of these curves that were species abundance, species diversity, evenness and the biomass, and the two peaks were apart from each forest belt by 6 - 8m. While the narrow spacing forest just had only one peak. Accordingly, herbage species diversity and biomass be maximum if the distance of the two belts were 12 - 16m.
