本文讨论了热带山地雨林采伐更新方式的生态环境因子。作者在研究水热变化特征基础上,试图为我国热带地区建立一个高生产力的森林模式。文中并阐述了森林对环境的影响,这一影响是依赖森林结构而变化的,并与幼树生长和天然更新有关。皆伐迹地水土流失严重,即使采用附近原始林的树种造林,因环境改变生长不良。显示了保护顶极群落的重要性。
This paper discusses the eco-environmental factors of the cutting and regeneration of tropical mountain rainforest. Based on the study of the characteristics of hydrothermal changes, the author tries to establish a high productive forest model for the tropical regions in China. The paper also describes the impact of forests on the environment, which is dependent on the structure of the forest and is related to the growth and natural regeneration of saplings. There are serious soil and water losses in the well-demarcated areas. Even with the afforestation of trees in the vicinity of the original forests, the growth is poor due to environmental changes. The importance of protecting the climax community is shown.
