Table 1 Comparison of 10 metrics on measuring patterns of endemism

方法 Metrics 特点 Characteristics 优点 Advantages 缺点 Disadvantages 应用现状 Application status 应用前景 Application perspectives 特有种丰富度 ER 物种同等重要 Equally important for every species 操作简单 Simple operation 所有物种等同重要 Equally important for all species 应用最为广泛, 当前全球以及洲际生物多样性热点地区确定研究中的重要参考标准 Most widely used. Having become an important reference standard for determining biodiversity hotspots at global and intercontinental levels 普遍运用 Popular 边界特有 TE 操作简单 Simple operation 特有区域的范围界定不明 Ambiguous delineation of area of endemism 确定特有现象的分布格局, 但主要针对个别类群的研究 Determining endemism distribution pattern only focusing on specific taxa 加权特有性 WE 根据空间分布范围设置权重 Setting weights according to spatial range of species 操作简单, 根据物种空间分布范围设定每个物种的权重 Simple operation. Setting weights of each species according to spatial range of species 揭示特有现象的分布中心 Defining the center of endemism 校正加权特有性 CWE 依据物种分布空间设定权重, 排除物种多样性本身的影响 Setting weights based on geographical range of species, excluding impact of species diversity 要求数据全面 Requiring comprehensive data 揭示特有现象的分布中心 Defining the center of endemism 特有性简约分析 PAE 空间分析单元为自然地理区域 Using geographical area as spatial analysis unit 引入分支生物地理学研究方法, 分析某个类群不同成员之间的进化关系 Introducing a cladistic biogeography methodology to analyze evolutionary relationships between different members of groups 局限适用于自然地理区域, 且涉及类群较少的分析 Application limited to geographic area, and appropriate study with a small amount of species 揭示特有现象分布中心 Defining the center of endemism 分支生物地理学专属研究方法 In the cladistic biogeography exclusively 样方式特有性简约分析 QPAE 空间分析单元为规则研究区域 Using regular area as spatial analysis unit 将系统进化关系与空间分布结合, 并引入群落生态学的研究方法 Combining evolutionary characters and geographical distribution, and borrowing methods of community ecology 多物种多区域无可操作性 Not operational for multi- species and multi- regions 揭示特有现象分布中心 Defining the center of endemism 谱系多样性 PD 强调系统进化多样性 Emphasis on phylogenetic diversity 反映进化特征 Reflecting evolutionary characteristics 获取精确到种的系统树困难 Being difficult for all de- scribed species to attain phylogenetic tree at a resolution of species 应用于高等分类群 In higher taxa 应用前景广泛 Wide applications in the future 物种进化特异性 ED 反映进化特征 Reflecting the evolutionary characteristics 获取精确到种的系统树困难 Being difficult for all de- scribed species to attain phylogenetic tree at a resolution of species 应用于个别类群 In minority groups 谱系特有性 PE 系统进化多样性与空间分布范围相结合 Combining evolutionary diversity and spatial range of species 考虑进化特征与地理空间分布 Considering evolutionary characters (time) and geographic distribution (space) 获取精确到种的系统树困难 Being difficult for all de- scribed species to attain phylogenetic tree at a resolution of species 个别类群应用(种级) In minority groups (species) 空间加权进化特异性 BED 考虑进化特征与地理空间分布 Considering evolutionary characters (time) and geographic distribution (space) 获取精确到种的系统树困难 Being difficult for all de- scribed species to attain phylogenetic tree at a resolution of species 应用于特有濒危等少数类群 In endemic and endangered groups
