摘　　要：通过采样分析对库布齐沙漠流动沙丘与固定沙丘沙粒径进行测定,对两类沙丘的沙物质粒径进行对比,分析沙粒的粒级变化规律。结果表明:实验区沙粒的粒径主要集中在0.25～0.05 mm范围内,约占总含量的95%左右;固定沙丘地表和流动沙丘<0.05 mm沙粒含量分别为1.406%和0.563%;固定沙丘地表和流动沙丘>0.25 mm沙粒含量分别为3.87%和4.49%。Through measuring and contrasting the particle diameter of sand in moving and fixed dune in Kubuqi Desert,the changing rule of particle diameter of sand was analyzed.The results show that in test district,most of particle diameter of sand concentrate in the range of 0.25～0.05 mm,taking up 95 percent of the total content.The content of sand with diameter less than 0.05 mm are 1.406% and 0.563% separately in the surface of fixed dune and moving dune.The content of sand with diameter bigger than 0.25 mm are 3.87% and 4.49% separately in the surface of fixed dune and moving dune.
