摘要(Abstract):

森林不但是一种水平格局上的镶嵌景观,而且其内部群落具有一定的垂直结构。传统的森林活力或生态评价只注重其中一方面。选择"目标群落"作为参照基准,计算与被评估群落"距离"的思想,为建立跨尺度、多要素的森林活力评价方法提供了契机。新的森林活力评价方法最初由Dvaid Parkes提出,Helmut进一步完善并使之系统化。笔者以石林世界公园的四种森林植被类型为研究对象,遵循"目标群落""距离"评价思想,建立了群落和景观尺度上的评价项目及其对应的计算指标,并努力结合两个尺度上的计算指标进行评价。
The forest is not only an inlaid landscape on the horizontal pattern,but also has a fixed vertical stratum in its internal community.The traditional evaluation of bush vitality and ecology merely attached importance to one of the above-mentioned two.The idea of choosing the "goal community" as the reference base to count the "disparity" from it to the evaluated community has provided the turning point to establish the cross-standard and multi-elements evaluation measure for bush vitality.David Parkes was the first person who has brought up the new evaluation measure for bush vitality, while Helmut went a step further to systemize it.The author took the four bush vegetation types in Shilin World Park as the object of study,following the evaluation ideas of "goal community" and "disparity",established the evaluation subjects and their corresponding counting-index for the community and landscape standard,and made efforts to combine the mentioned counting-index on the two standards to carry out the evaluation.
