摘　　要：对麦薯带状间作农田土壤的抗风蚀能力进行了探讨．结果表明，该措施能够减少水分蒸发，增加地表土壤含水率0．22％～2．6％，增大地表空气动力学粗糙度0.03～3.81cm，降低近地表风速6％～46％，减少土壤风蚀0．5％～84％．在定量研究的基础上，提出了翻耕带有效抗风蚀宽度为5m．This paper investigated the capability of wind erosion resistance of strip intercropping farmland with wheat and potato in the region. The results showed that the measure can decrease soil water evapora- tion. The soil moisture content increased by 0.22 % - 2.6 % ; the surface aerodynamic roughness increased by 0.03 - 3.81 cm ; near surface wind velocity lowered by 6 % - 46 %, the wind erosion amount reduced by 0.5 % - 84 %. Based on the quantitative study, the paper put forward that the effective width to resist wind erosion of strip ploughed land is 5 m.
