摘　　要：生物多样性是生物及其与环境形成的生态复合体以及与此相关的各种生态过程的总和，包括数以百万计的动物、植物、微生物和它们所拥有的基因以及它们与其生存环境形成的复杂的生态系统。本文构建了一个生物多样性评价指标体系，遴选了10个评价指标，确立了生物多样性评价的方法，并以安徽省为例，以县域为评价单元，开展了生物多样性综合评价，评价结果显示，安徽省79个县域单元中，生物多样性评价等级为“高”的有2个，评价等级为“中”的有19个，评价等级为“一般”的有27个，评价等级为“差”的有31个。Biodiversity was the sum of organisms, ecological compound generated by organisms and their environment and related variety of ecological processes. It contained millions of animals, plants, microorganisms, their genes and complex ecosys- tems made of all the organisms with their living environment. This paper developed a biodiversity assessment index system and se- lected 10 evaluation indexes, establishing methods for biodiversity assessment and taking county area in Anhui Province as the e- valuation unit to carry on evaluation of biological diversity. The results showed that among the seventy - nine counties under research, two was graded as ＂high level＂, nineteen was graded as ＂medium level＂, twenty seven was graded as ＂general level＂ and thirty one was graded as ＂low level＂.
