Abstract:: The substance of oasis stability is coordinate of man-land relationship and get sustainable development.The paper studies on oasis stability in oasis-desert ecotones through the spatial variability of soil property.Typical oasis-desert ecotones are selected as the experimental area in Longqu village,Zhangye City of Gansu province.Through the test of soil samples in laboratory,seven soil characteristic value(soil moisture content,soil salt content,pH,mechanical composition,bulk density,available phosphorus and nitrogen content) were analyzed on the different landscape spatial variability using ArcGIS 8.0 software.From the research,we know the variability of soil property value have hierarchy and deduction at different landscape pattern,which tightlink with different landuse level on oasis edge.It can help us know the maintain problems of oasis ecology stability and sustainable developing more scientific.
