摘　　要：本文着重研究了塔克拉玛干沙漠盐土荒漠的形成演变，表明了盐土荒漠多形成于地下水位较高的区域。在盐土荒漠形成初期，盐分含量低，表聚性不明显；在中期阶段，盐分已有明显的表聚性，但盐壳厚度不大；到了高级阶段，它已形成坚硬的盐壳，盐分含量很高。在盐土荒漠与沙丘形成的复区内沙丘的含盐量较高，同时在盐土荒漠的演变中，坚硬的盐壳减缓了地表侵蚀和沙丘的形成。The paper mainly studies the formation and change of solonchak desert in the TaklimakanDesert. It shows that the solonchak desert forms in the areas of high groundwater table. The solonchakdesert has low salt content and no obvious salt surface accumulation in the preliminary stage,Itincreases salt content and has thin salt crust in the middle stage,Sand dune often has high salt content in the solonchak-sand dune complex. In addition , hard salt crust lightens the erosion of soil surface and the formation of sand dune in the solonchak desert area.
