摘　　要：生态敏感性评价是反映国家公园生态问题与保护利用关系的重要手段,对国家公园规划建设具有一定的理论和实践指导意义。文章以祁连山国家公园肃南片区为例,基于现存主要生态问题,采用层次分析法(AHP)确定评价因子权重,并运用ArcGIS空间分析方法完成了肃南片区的生态敏感性综合评价。结果表明,祁连山国家公园肃南片区的综合生态敏感性总体处于中等偏高的水平,中等敏感性以上地区占总面积的78.90%;空间分布呈现由东北至西南逐渐增加的趋势。根据祁连山国家公园肃南片区综合生态敏感性评价结果,针对不同敏感性级别的区域提出了差异化的保护管理模式。Ecological sensitivity evaluation is an important means to reflect the relationship between ecological issues and protection and utilization in national parks,and has certain theoretical and practical guiding significance for the planning and construction of the national park.This paper takes Sunan area of Qilian Mountain National Park as an example,based on the existing major ecological problems,uses the Analytic Hierarchy Process(AHP)to determine the weights of evaluation factors,and then uses ArcGIS spatial analysis method to complete the comprehensive evaluation of ecological sensitivity in Sunan area.The results show that the overall ecological sensitivity of Sunan area in Qilian Mountain National Park is at a moderately high level,with areas above medium sensitivity accounting for 78.90%of the total area.The spatial distribution shows a gradually increasing trend from northeast to southwest.Therefore,based on the comprehensive evaluation results of ecological sensitivity in Sunan area of Qilian Mountain National Park,differentiated protection and management modes are proposed for areas with different levels of sensitivity.
