通过小尺度干扰对森林植物多样性影响的田间实验及连续3次的观测分析，探讨干扰与资源总量对植物多样性的影响规律.结果表明:人为小尺度干扰提高植物生长初期的丰富度、均匀度和多样性指数;物种多样性指数与土壤中有机质等养分的含量呈正相关.小尺度干扰和资源总量是影响局域多样性的2个重要因子,小尺度干扰的影响独立于基质性质.小尺度干扰造成的异质性对次年多样性的作用减弱，干扰对资源有效性的提高具有暂时性或过渡性.

The influences of small-scale disturbance on forest plant diversity were studied based on the experiments in the field. The conclusion was that the man-made small-scale disturbance could make a favor in plant germination and gave a rise to diversity index during their early growth could and there was a positive relationship between the species diversity and soil nutrients.Small-scale disturbance and resource quality were two major factors in local diversity preservation,and the effect of small-scale disturbance on species diversity was independent on matrix quality.The result from three time successive observations was that the effect of heterogeneity of small-scale disturbance on species diversity in the next year declined.That is to say,the increase of resource efficiency by the disturbance was of temporary or transition ary meanings.
