摘　　要：东北虎是我国国家一级保护动物,由于人类活动不断增强,这在很大程度上改变了它们的生存环境,使之数量急剧下降,对其未来生存和繁衍造成威胁.本文以吉林省珲春市为研究区,基于3S技术,通过解译卫星遥感影像及分析数字高程模型,从单因子和综合因子两方面对珲春地区的适宜性进行评价.结果显示,研究区较适合野生东北虎的生存,但人类活动是影响其生境的最主要因素.Amur tigers are mainly live in Northeast China ,with the constantly intensified activities of human ,their survival environments are largely changed and their population decreased rapidly ,threatening their survival and propagation in the future .This paper assessed the adaptability of the Amur tigers in Hunchun , Jilin Province , China .Theadaptability is assessed through remote sensing images and digital elevation modelfrom two factors ：single factor and comprehensive factor .The results demonstrated that ,for Amur tigers the study area is suitable to live,human activities are the primary factors to influence their survival environments , and that we should take effective measures to improve their survival environments and recover their population as soon as possible .
