As an important and typical arid inland region in China,Shiyang River Basin plays an important role in maintaining the sus-tainable development of eco-environment,whose ecological land suitability restricts the development of the local human activities.Therefore,Shiyang River Basin was selected as the case study,the minimum cumulative resistance(MCR)model and GIS technique were integrated to create land suitability evaluation map.We calculated the MCR value of ecological source and living source,and di-vided the whole basin into five partitions according to the difference between ecological source and living source,and analyzed the pat-terns and characteristics of the ecological land suitability evaluation(ELSE)regions,respectively.The results showed that:1)The suit-able ecological land includes prohibited development region and restricted development region,which accounts for 15.45％and 23.35％of the total land area of the Shiyang River Basin,respectively.These two regions mainly distributed high altitude region in the southern Qilian Mountain and low altitude region where had high density of rivers.2)The protection of ecological land requires not only con-serving existing ecological land but also focusing on ecological buffer belts around ecological sources and improving ecological land service ability.3)Ecological networks should be constructed through artificial planting trees around the boundary of oasis and ecologic-al restoration region.Buffer greenbelts should also be established between optimized development region and ecological restoration re-gion.
