摘　　要：在榆林风沙区铁路防护林建设过程中,通过开展地膜等材料覆盖抗旱造林试验,结果证明选用普通地膜、柴草、黄土、煤矸石等材料覆盖造林能有效减少土壤水分蒸发散失,增加土壤水分含量,促进造林苗木的成活和生长,显著提高造林成活率和保存率。In the course of protective plantation establishment along the railway in the sandy area of Yulin, drought--tolerant techniques like mulching were often applied. The result showed that ordinary plastic film, straw,loess as well as coal gangue could effectively reduce the evaporation of water from the soil and improve the survival rate and growth of trees.
