摘要:
贵州省天然林保护工程中低效林面积所占比重很大，低效林改造的效果好坏，直接影响到天然林保护工程质量。对封改、封抚、封造3种经营类型低效林复位调查及多样性指数分析表明：乔木层物种、株数都有大幅度的增加，林分结构趋向均匀，优势种仍是杉木、檫木，但很多目的树种进入到了乔木层。灌木层物种减少，数量减少，优势度下降，均匀度提高，杂灌减少，目的树种数量和物种增加，整个林分结构向针阔混交林方向发展。
Abstract:
There is a large proportion of low-quality and benefit forest in Project of Natural Forest Resource Projection in Guizhou province, the improved effect of low-quality and benefit forest directly affects the quality of Project of Natural Forest Resource Projection. The growth of three working-groups of closed tackling and reconstruct, closed tackling and thinning, closed tackling and forestation low-quality and benefit forest were investigated and the diversity index was analyzed. The result showed: the number of species and individual were increased, the trend of forest structure is more equality, dominant species are Cunninghmia lancelata, Sassafras tsumu, but large numbers of target species had grown into the layer of arbor. The species and number of shrub reduced, dominance descended, and miscellaneous shrub lessened, target species increased, the whole forest structure are changing to mixed forests.
