基于人为干扰度分级体系,将白马雪山国家级自然保护区德钦分局干扰度分为6个等级(无干扰、微弱干扰、轻度干扰、中度干扰、重度干扰及完全干扰),并对2006年和2016年人为干扰程度进行定量分析和评估.结果表明,随时间的推移,无干扰和重度干扰面积有所下降,其余干扰类型面积不同程度增加;2016年人为干扰指数与2006年相比有所增加,人为干扰逐渐增强,特别是核心区干扰幅度较大.针对干扰情况提出了相应的保护管理措施.%Based on hemeroby theory,the research area in Deqen Branch of Baima Snow Mountain Na-tional Nature Reserve were classified into six disturbance levels(no human disturbance,weak human dis-turbance,moderate human disturbance,moderate-strong human disturbance,strong human disturbance and complete human disturbance).The quantitative analysis and evaluation of hemeroby in 2006 and 2016 showed that the area of no human disturbance and strong human disturbance were decreased with time,while the area of other disturbance types increased in different degrees.Compared with the hemero-by in 2006,the hemeroby index increased in 2016 with the gradually increasing human disturbance,es-pecially in the core area.This paper put forward the corresponding protection and management measures for this situation.
