采用样方法调查了不同坡向油松中龄林林下植物种类、数量及生长情况，通过对灌木层和草本层植物丰富度指数、多样性指数、均匀度指数等指标的计算，研究了油松中龄林林下植物多样性，结果表明，油松中龄林林下植物共有26科60属66种，不同坡向对林下植物结构和多样性均有影响，阴坡林下草本植物结构及多样性均好于阳坡，阳坡灌木层丰富度高于阴坡；光照强度和林下水分是影响林下植物的重要因素。

With the quadrat method ,the understory plant species ,quantity and grow th sta‐tus of half‐mature Pinus tabulae f ormis forest stand on the different slopes were surveyed . Through the calculation of plant richness index ,diversity index ,evenness index index shrub layer and herb layer ,the undergrow th plant diversity of half - mature Pinus tabulae f ormis forest was studied ,providing the theory basis for its plantation undergrowth vegetation con‐struction and stable forest ecosystem establishment .The results showed that there are 26 families ,60 genera ,66 species and all of the slopes are supposed to affect the structure and di‐versity of undergrow th plants , and the undergrowth herb structure and diversity on the shady slope were better than those on the sunny slope ,while the richness of shrub layer on the sunny slope was higher than that on the shady slope .Additionally ,light intensity and water are the important factors influencing the undergrow th vegetation .
