| 摘 要： | 基于生态重要性,以重要物种空间分布种数为参数构建生物多样性保护重要性评价模型,以陇南市为例,乡镇为研究单元,基于模型对全市生物多样性保护重要性进行评价,基于评价结果将研究区分为优先补偿区、次级优先补偿区、次级补偿区和潜在补偿区,对各等级补偿区的特征分析结果表明:①各类补偿区分布相对集中,优先补偿区主要分布在陇南市南部,集中分布在文县。②各等级补偿区由高到低在补偿面积、补偿乡镇数量和补偿人口方面不断增加。③优先补偿区范围相对较小,而次级优先补偿区和次级补偿区范围相对较大,潜在补偿区占很大的比例。④优先补偿区与自然保护区有着密切的联系,大多数优先补偿乡镇位于自然保护区内。

| Abstract: | The paper constructs an evaluation model of the importance of biodiversity conservation based on ecological importance which takes into account spatial distribution of key species.Taking Longnan as an example,and taking towns as basic unit,the whole area is classified by cluster analysis based on the evaluation results into four compensation zones: the priority zones of compensation,sub-priority compensation zones,secondary compensation zones,and potential compensation zones,and the relevant characteristics... |
