摘　　要：沙漠"土壤化"是通过力学手段使沙漠表层沙子"土壤化",使其获得土壤的生态-力学属性,同时获得与土壤一样的存储水分、养分和空气的能力,进而成为植物生长的理想载体的一种快速沙漠生态恢复手段。介绍了沙子"土壤化"的力学原理和沙漠"土壤化"的实现方法,总结了前期的实验研究与沙漠实地试验效果。Desert＂soilization＂is a rapid and effective technique to restore desert ecology,which is realized by enabling the surface layer of sand to acquire the eco-mechanical attributes of soil as well as the abilities to conserve water,nutrients and air,so as to serve as an ideal habitat for plant species. The mechanical principles and implementation methods of desert＂soilization＂were introduced,and the results of present experimental researches both in the simulated desert landform conditions and in actual desert were presented.
