中文摘要	本文利用粉煤灰和城市污泥配施对毛乌素沙漠南缘的沙漠土进行了土壤改良实验，以玉米盆栽试验效果探讨了可行性，实现了国内外首次用固体废弃物配施改良沙漠土的实验研究。结果表明：1）添加固体废弃物使土壤养分含量显著提高，有害元素均低于土壤环境质量要求的标准，C/N值符合土壤栽培要求；2）大大改善了土壤的物理性质，使沙漠土容重降低，孔隙度增加，保水保肥性明显提高，pH明显降低，节约用水45％～48％；3）将本区沙漠土（松沙土）改造为沙壤土和轻壤土。实验对干旱缺水的沙漠进行农作物种植、恢复生态环境有重要意义，也使固体废弃物得以资源化利用。
英文摘要	In this study, combined urban solid wastes including coal ash and sewage sludge have been firstly used to test if they could meliorate the quality of desert soil in the Maowusu Desert, south edge of the Yulin City of Shaanxi Province. The feasibility of this method has been discussed through the experiment of corn growing in pot. The results are given below. （1） With the addition of urban solid wastes into the desert soil, the nutrient contents of the treated desert soil are significantly increased, heavy metal contents of the treated desert soil are lower than the soil environmental quality standards, and the C/N ratios are in accordance with the soil standards. （2）With the addition of urban solid wastes into the desert soil, the physical properties of the treated desert soil has been greatly improved, as its bulk density is decreased,its porosity is increased,its fertilizer and water conservation capability is improved significantly,and its p H value is decreased obviously with the water consumption decreased 44% to 48%. （3） The desert soil （coarse sandy soil） has been changed as a sandy loam and light loam. This is of great significance for cultivating plant and restoring the ecological environment of the arid desert areas and for effectively reutilizing the urban solid wastes simultaneously.
