This paper is based on the systems analysis natural conditions,socio-economi-c, potential remediation, environment of Qitai domain, its build land remediation parti-tion index system, using factor analysis and cluster analysis, supplemented by land re-mediation zoning designation GIS platform, reveal the status of land use in the count-y, andthe presence of outstanding issues on the basic, Proposed direction and prioritie-s of the county district land remediation. The results shows that such influence is sim-ilar to the typical county land remediation partition factor in arid areas are mainly co-ncentrated in odd sets of annual precipitation, irrigation assurance degree, agricultural land quality; sunlight, water and soilmatching coefficient; proportion of non-agricult-ural population, the per capita residential area; forest coverage, etc. aspects. However, due to circumstances vary widely county arid region, in particular the implementatio-n of land remediation process, only local conditions, play to their strengths in order t-o a-chieve the overall efficiency of land remediation.
