摘　　要：通过分析四川阿坝县、若尔盖县和红原县湿地区域的植被、景观类型、指示物种和人口密度、交通路网密度等指标,对该区域生态系统的区域代表性、生态系统完整性和原真性进行了研究。结果表明,阿若红沼泽化平坦高原区生态区位典型,特有物种丰富,国家代表性强;区域景观类型连通性高,内部结构完整性和聚集度高;区域自然性指数极高,人为干扰活动弱,生态系统结构完整性和原真性高;该区域具有国家代表性的高寒湿地生物多样性区域,适宜设立为国家公园。Based on the analysis of vegetation,landscape types,indicator species,population density and traffic network density in Aba,Ruoergai and Hongyuan counties of Sichuan province,the regional representation,integrity and authenticity of the ecosystem in this region were studied.The results showed that aruohong marsh flat plateau had a typical location,rich endemic species and strong national representation.The regional landscape type had high connectivity,internal structure integrity and high degree of aggregation,the regional nature index was very high,the human disturbance activity was weak,and the e-cosystem structure integrity and authenticity were high.This region was a representative alpine wedand biodiversity area,which was suitable to be set up as a national park.
