研究了泰山3种类型刺槐人工林林下植被的垂直结构和物种多样性,结果表明:(1)刺槐侧柏混交林下灌木层的高度、盖度及草本层高度为最大,刺槐油松混交林次之,刺槐纯林最小;草本层的盖度表现为刺槐油松混交林>刺槐侧柏混交林>刺槐纯林.(2)刺槐纯林灌木层和草本层的丰富度指数、物种多样性指数最小,而均匀度指数最大;刺槐油松混交林除灌木层的Simpson指数较低外,其丰富度指数、草本层多样性指数、均匀度指数均高于刺槐侧柏混交林.(3)建议营建混交林以提高森林的生态功能.

The vertical structure and species diversity of different types of artificial R. pseudoacacia forest commu?nities were studies. The results were as follows:(1)Shrub layers’height and coverage and herb layers’height were mixed R. pseudoacacia and Platycladus orientalis forest>mixed R. pseudoacacia and Pinus tabulaeformis for?est>R. pseudoacacia forest,but herb layers’coverage was mixed R. pseudoacacia and P. tabulaeformis forest>mixed R. pseudoacacia and P. orientalis forest>R. pseudoacacia forest.(2)The R. pseudoacacia forest had the low?est richness and diversity in shrub and herb layers,but had the highest evenness;mixed P. tabulaeformis and R. pseudoacacia forest had a higher richness,diversity and evenness than R. pseudoacacia and P. orientalis for?est except the Simpson index in shrub layer.(3) Mixed forest should be constructed in order to improve the eco?logical function.
