GAP分析及其在生物多样性保护中的应用现状

GAP analysis and its application to the bio-diversity protection

GAP分析即保护生物多样性的地理学方法(A Geographic Approach to Protect Biological Diversity),是快速概观生物多样性集中要素的分布和保护状态的一种方法,是一个寻找保护区系统中没有被代表或充分代表的物种及植被类型(Gaps)进而确定其所在区域的过程。它集中在生物有机体更高层,基于生境保护和多物种保护的双重目的,已被证明是保护大尺度生物多样性行之有效的方法之一。在对GAP分析的概念、内涵、一般步骤和精度评估阐述的基础上,分析了GAP分析的优势和不足,并探讨了其在生物多样性保护中的应用现状及在中国发展的前景展望。

GAP Analysis （a geographic approach to protect biological diversity） is a quick approach to identify the distribu- tion and protection of biodiversity. It＇s helpful to find and notarize regions where need to be protected urgently but not actually （these regions are usually called ＂gaps＂）. GAP analysis focuses on a higher level of organisms, and aims protect not only biodiversity, but also biohabitats. It has been proved to he an effective approach to protect biodiversity to a large extent. Based on a general explanation of GAP analysis,including its concept, connotation, routine process and precision assessment and so on. This paper not only analyzes its superiorities and deficiencies,but also discusses its actual and future application to the biodiversity protection in China.
