论生物多样性的保护问题

On the conservation of biodiversity

当前，任何地区的生物多样性都是自然和社会因素长期综合作用所造成。生物多样性最丰富的地区不一定全部由顶极植被所覆盖，而常常是一些包括所有演替类型的地方。本文通过讨论自然环境的变化和人类生产活动对不同区域景观的影响，探讨有关生物多样性的保护问题。

The biodiversity of any region today is the result of complex historical interactions among physical and socialforces over time. Virtually,the region which has rich biodiveristy,is not certainly covered by vegetation of climax types;those regions including all serial communities alway,have greatest biodiversity. The paper deals with biodiversity conser-vation through discussing the influences of physical changes and human activities on regional landscapes.
