Therefore, with some engineering and biological measures, after some pioneer trees are planted in extremely degraded tropical areas,the pioneer forest should be reformed by multilayer and multispecies broad leaved mixed forest in time, wihich could accelerate the development of artificial forest into local climax community.

因此，对于极度退化的热带丘陵台地区，在一定工程和生物措施基础上，用先锋绿化树种造林成功后，及时用多层多种的阔叶混交林改造原有先锋林，可以加速人工林向地带性植被类型演替。

The forest was characterized with phanerophyte evergreen plants with single-mesophyll-leathery leaves, which reflected the nature of tropical Karst mountainous seasonal rain forest.(2). Community succession was divided into five stages by using Cluster method, PCA method; the succesion stages include herbaceous stage, scrub-shrub stage, small tree stage, arbor stage and climax seasonal rain forest stage.(3). Based on similarity theory, succession sere was constructed with the community similarity equation formed.

结果表明：(1)森林群落在外貌上，以常绿高位芽、单叶、革质、中型叶植物为主，反映了热带岩溶山地季雨林的特点；(2)运用聚类分析、PCA排序等方法将群落演替阶段划分为草本群落阶段、灌丛阶段、小乔木阶段、乔林阶段、顶极季雨林阶段；(3)运用相似学原理，组建群落间相似度方程并以此方程构建了群落演替系列；(4)研究表明桂西南岩溶区生态系统健康受到严重胁迫。

Based on the information taken from the subcompartmental records a comparison between the actual and normal forests was made and a new point of view was proposed in the article: in the case of cultivating timber-forest which is different in cutover age, age class and growing speed within the range of the whole forest station, the forest age class distribution showing the opposite shape of "J" is of more benefit to keeping the relative stability of all the age class area than the age class distribution of th...

本文在统计森林资源小班档案卡片有关资料的基础上，把现实林分与法正林相比较，用法正林学说来指导全场森林的调查。并提出了一个新的观点：在整个经营单位内，培育不同生长速度，不同主伐年龄，龄级期不同的用材树种，森林的龄级结构呈反"J"形分布此法正分布更有利于维持各龄级面积的相对稳定，并且，年伐量的波动不大，有利于森林的永续利用。
