热带林地的开垦、培育和废弃导致了热带次生林面积的迅速增加。然而，尽管这些森林的面积越来越大，但生态学家、林学家和自然资源保护者对它们的关注相对较少。在本条中，“次生林”一词的使用仅限于在清除后重新占据某一地点的森林。选择性采伐和其他干扰导致的森林被排除在外，这些干扰允许大多数植物物种在该地点生存。回顾了有关热带森林演替的文献，指出了干扰的类型、强度和规模、周围景观的性质以及幸存的散布动物的组成的重要性。从调节功能、商业价值和保护意义等方面比较了热带次生林和原始林的价值。最后，简要讨论了主要的研究需求。
The clearance, cultivation and abandonment of tropical forest lands has resulted in a rapid increase in the area of tropical secondary forests. Despite their growing extent, however, these forests have received relatively little attention from ecologists, foresters and conservationists. In this article the use of the term 'secondary forest' is restricted to forests which have reoccupied a site after clearance. Forests resulting from selective logging and other disturbances which permit most plant species to survive on the site are excluded. The literature on tropical forest succession is reviewed, showing the importance of the type, intensity and scale of the disturbance, the nature of the surrounding landscape and the composition of the surviving disperser fauna. The value of tropical secondary forests is compared to primary forest, with regards to regulatory function, commercial value and conservation significance. Finally, major research needs are briefly discussed.
