摘　　要： 生物多样性保护的优先性研究是目前资助机构和保护专家关注的热点 ,热点地区分析和GAP分析是进行生物多样性优先性分析的两种方法。热点地区分析是根据物种丰富度和特有度 ,探讨怎样以最小的代价 ,最大限度地保护区域的生物多样性。GAP分析综合考虑区域陆生脊椎动物物种、土地覆盖类型及土地所有权和保护状况等方面信息 ,在保护土地管理实践中 ,使具有代表性的植被类型、重要物种都得到保护。本文介绍了热点地区和GAP分析的概念、基本假设、步骤以及在生物多样性保护中的应用。 Priority setting for biodiversity conservation is a major concern for funding agencies and conservationists. Hot spot analysis and GAP analysis are two kinds of methods for priority setting. Hot spot analysis attempts to protect maximum biodiversity under limited funding supports based on species richness and endemism. GAP analysis was developed as a coarse filter approach to protect biodiversity, provided an overview of the distribution of terrestrial vertebrates and land cover types, relative to special management areas and land ownership. GAP analysis seeks to identify “gaps” (i.e., vegetation types or species not adequately represented in areas managed for long_term maintenance or natural system) that may be filled through changes in land management practices. This concepts, assumptions, basic steps and applications of hot spot analysis and GAP analysis were discussed in this paper.
