对由天然针阔混交林或天然阔叶林经过人为改造和抚育转变成的4类毛竹林(即成林原因相同的4种林型-强度干扰下的毛竹纯林,较强干扰下的竹杉混交林,较弱干扰下的竹阔混交林,弱度干扰下的竹杉阔混交林)的层次结构、物种组成、物种丰富度、α多样性及群落相似性经营强度对毛竹林植物多样性的影响进行了对比分析.结果表明:这4种人工毛竹林随着经营强度的加大,层次结构逐渐简单化,乔木层、灌木层和草本层的物种丰富度迅速下降,且物种组成发生显著变化.乔木层、灌木层和草本层的生物多样性总体也呈下降趋势,但灌木层和草本层的生物多样性竹阔混交林类型反倒略高于经营强度最弱的竹杉阔混交林类型.而且不同经营强度下所形成的这4种类型毛竹林的群落相似性也随着经营强度的增加而降低,其中毛竹纯林与其他3类的相似性最低.

By the natural mixed coniferous and broad-leaved forest after a natural or man-bringing and transform into the four categories of Mao bamboo, Lin put the reasons for the same four-Lin-interfere with the strength of pure bamboo, bamboo under strong interference Sequoia Mixed forest, less interference of broad-leaved mixed forest of bamboo, the weak degree of interference Chuk wide fir forest. Its hierarchical structure, species composition, species richness, α diversity and community similarity were compared and analyzed. Artificial hair for more than four bamboos as the operating level, increase the intensity gradually simplified the structure, tree layer, shrub layer and herb layer of the rapid decline in species richness and species composition of significant change. Tree layer, shrub layer and herb layer of biological diversity in general has declined, but the shrub layer and herb layer of biodiversity wide bamboo forest type on the contrary was slightly higher than the operating strength of the weakest type of broad-leaved mixed forest of bamboo fir. And the strength to operate under a different form of four types of bamboo the hair similar to the community is also operating as an increase in intensity and lower, with pure bamboo and other similarity of the lowest three categories.
