摘要 在非洲人口迅速和持续增长的巨大压力下,非洲的植被正在以空前的速率退化。本文阐述了烧荒、非林化、耕种、牲畜和野生动物对非洲植被的影响。最后就非洲植被保护问题提出了一些看法。 Of all elements of the physical environment, vegetation is possibly the most vulnerable to change by human activities. Under the enormous pressure of African population with rapid and continued growth, its vegetation today is deteriorating at an unprecedented speed. In Africa the main sabotage destructive activities are clear cut, burning and overgrazing. In the paper, the impacts of fire, deforestation, cultivation, livestocks and wild animals on the vegetation are expounded respectively. Ideas for African vegetation protection are also explained.
