Abstract对阿拉尔-和田沙漠公路沿线机械防沙体系内外地表风沙沉积物进行了系统采样,运用沉积物的粒度分析方法,以流沙区为对照,对比分析了沙漠公路机械防沙体系中阻沙区和固沙区内风沙沉积物的粒度特征.研究发现:(1)从流沙区到阻沙区,再到固沙区,风沙沉积物的粗砂、中砂含量逐渐降低,极细砂、粉砂含量逐渐增加,阻沙区内风沙沉积物的平均粒径减小了31.0%,固沙区内风沙沉积物的平均粒径减小了47.2%.(2)流沙区、阻沙区和固沙区内蠕-跃截点的平均值分别为1.296Φ、1.647Φ、2.188Φ,跃-悬截点的平均值分别为3.893Φ、4.089Φ、4.292Φ,各运动组分的截点均向细端偏移,并且各运动组分的含量也发生了变化,阻沙区和固沙区内蠕移组分含量分别降低了2.378%、5.837%,悬移组分含量分别增加了4.26%、4.294%.(3)固沙区沙粒的分选性最好,偏度Sk的平均值为-0.059,表现为近对称,峰态KG为0.939-0.987,表现为中等峰态.
