【摘要】 GAP分析是用来判别生物多样性保护的空白、遗漏区域(“gaps”)和需要采取保护行动的地区(conservation gap),它是一种评估区域生物多样性所有成分所处保护地位、被保护程度等的科学方法。强调最大限度地保护生物多样性的先决条件是通过构建保护区网络,不仅仅考虑生物多样性最高地区,应该使本地种和生态系统都得到保护。区域生态安全格局的评价不仅要考虑生物及其生境的保护,而且,更要考虑受损生态系统和破坏景观的恢复,即不仅考虑Conservation G ap,也要考虑R estoration G ap。因而,改进GAP方法可用于生态安全格局的分析与评价,且有望成为重要的研究手段。更多还原

【Abstract】 GAP analysis is a geographic approach which combines individual species conservation with regional biodiversity conservation.GAP efforts identify"gaps"and areas that need conservation.It is a scientific approach to appraise the conservation status of all elements of the regional biodiversity.GAP stresses that the prerequisite of biodiversity conservation is to establish reserve networks.It considers not only the richest biodiversity areas but also the local species and ecosystems.Assessing the regional pattern for ecological security must consider the species and habitats conservation as well as the restoration of the damaged ecosystems and destroyed landscapes,in another word,not only conservation gap,but restoration gap should be considered.Therefore,the extended GAP approach can be applied to the analysis and assessment of ecological security pattern,and is a promising research method.更多还原
