| 摘 要： | 海南岛西南部热带山地雨林采伐迹地上的更新群落大多数是以闽粤栲占优势的森林植被。本文以尖峰岭为例，对热带山地雨林不同采伐方式迹地上更新的群落进行了群落数量特征、种群年龄结构的分析。同时从林业生产的角度，评定了群落的更新质量，并提出了热带山地雨林适宜的采伐方式和群落更新的抚育管理方法。

| Abstract: | On the Jianfengling Ridge, Hainan Island, after the tropical mountain rain forest was cut, the dominant species of the regeneration communities on the cutting blanks is Castanopsis fissa. The authors studied the characteristics of two regeneration communities one regenerated on a large cutting blank and ten-year after cutting there had a tending action taken, another regenerated on a small cutting blank (about 0.25 ha) and had no tending action taken. The characteristics being compared were the Important Values (Ⅳ.)of the plan populations, the population diversity and the age structure. The regeneration quality of the two communities was also evaluated.The results indicated the two communities had outstanding differences. The community characteristics and regeneration quality on the small cutting blank was much better than those on the large one. The authors think that the cutting method of tropical mountain rain forest should be small cutting blanks which are separated from each other, because there are adequate and equitable seed sources for all the main species provided by the sorrounding forest. And using separated small cutting blanks will neither damage the ecological environment nor cause low regeneration quality of communities. So, it is possible for the regeneration communities on the small cutting blanks to lead to its climax communities in a short time.The spontaneous succession of these kinds of regeneration communities have the best structure to utilize the non-biological resoures, such as fertile soil and good tropical weather. From the results, the tending action is not needed for the regeneration communities, except for speciel forest purposes.There are still two problems that need more experiments. First to define an exact size of small area for cutting. The cutting area must both maintain the ecological balance and make the cutting department have maximum economic efficiency. Second, to define a suitable tending strength in the regeneration communities which are for special forest purposes. In addition, the authors have made a standard of dividing the tree age classes by the tree sizes, which is only suitable in the tropical mountain rain forest because the trees there grow rapidly. |
