摘要
生物多样性是有机界一个无所不包的术语，系指一个生态系统、一个区域乃至整个地球物种（包括动物、植物和微生物）丰富和均匀的程度。它既包含生物之间以及生物与环境之间复杂的相互关系的含义，也反映一个区域的发展规划是否符合客观规律的重要标志。可从遗传多样性、物种多样性和生态系统多样性三个不同水平来研究和分析其基本特点，当然，不同水平研究的关系是非常密切的。本文主要介绍其当前的基本情况、研究的战略思想、目标和主要研究内容，以期引起有关方面的重视，组织力量开展研究。
Biodiversity, a term all-embracing in organic world, refers to the extent of abundancy and evenness of species (including animal, plant and microorganism)in an ecosystem, a region and even the Earth. It either implies the complex interaction of organisms and that of organisms and environment or acts as an important indicator judging whether a regional development planning accords with objective law. The basic characteristics of biodiversity can be dealt with and analyzed in terms of three different levels of genetic diversity, species diversity and ecosystem diversity. The study of different levels is of course closely interrelated. The focus of the paper is to introduce- present conditions of biodiversity, strategic ideas of its study,objectives and major research content with the aim of arousing the attention of pertinent agencies to initiate studies of this field.
