摘　　要：依据中国干旱土系统分类研究最新进展,在首次方案基础上,经我们在干旱地区多年工作的实践,现提出新疆干旱土分类的修订方案,供同行进一步检验,讨论和试行,以进一步完善我国干旱土系统分类方案。The aridisols of Xinjiang are forming vast aridisol zone in mid-Asia with Ka-zakstan,Uzbecksitan and Turkinenstan. The sub-orders of aridisols are divided as follows. G1 There is cold in temperature regime altoeryic aridisol G2 The other aridisols:There is an upper limit of subsurface layer to 100cm a calcic layer calcic aridirol G3 the other aridirols: there is an upper limit of sub—surface layer to 100cm luvic argillic or alkalic argillic layer argillic aridisol G4 The other aridisols: at least possesses one of the following layer: secondary argillic layey,haplo layer, residual salic layer,and gypsic layer outhic aridisol
