摘要： <正>从植物多样性角度探讨了不同间伐强度对人工油松中龄林的影响，分析了林下植被的生物多样性。结果表明：在相似地力条件下，随着间伐强度的增加，林下植被科、属、种的数量增加，植物多样性增加，尤其是草本层多样性指数、丰富度指数、均匀度指数均逐渐上升，层次结构更加明显；间伐强度的增加改变了林下植被的生活型谱，阳生、喜暖植物的比例增加，同时有利于林下植被生物量的增加。对相似立地条件下45年生初植密度为3500株/hm2的油松中龄林选择44%的间伐强度处理，3年后林下植被发育及乔木生长状况较好。

Abstract: Virtual reality technology is one of integrated information technologies appeared at the end of the 20th century. The characteristics of virtual reality technology was expounded. The applications of virtual reality technology in the landscape architecture were explored. The obstacles which restrict virtual reality technology’s development in the field of landscape architecture were analyzed. The prospect of scenic landscape design in the future was given in the end of the paper.
