摘要
针对小江流域内不同的土壤类型和土地利用类型,通过实验对小江流域土壤抗崩性进行研究,结果表明:小江流域的土壤具有较大抗崩性,其中棕壤的平均崩解速率最大,黄红壤的平均崩解速率最小;从土地利用的角度看,林草地的平均崩解速率最小,灌丛其次,裸坡的平均崩解速率最大;小江流域土壤的崩解速率与土壤中<0.002mm的颗粒含量之间存在明显的负相关关系。
By making experiments,anti-collapse ability of soil in Xiaojiang River Basin is researched in the different soil types and land use types, The result indicates anti-collapse ability of soil in Xiaojiang River Basin is great;The average collapse velocity of brown soil is bigger than the others. The average collapse velocity of yellow-red soil is the least; in terms of land use, the grassland is the biggest in anti-collapse, the farmland and scrublands is less than grassland in anti-collapse,and the bare slope is the least in anti-collapse; the anti-collapse ability of soil in Xiaojiang River Basin is in inverse proportion to the contents of grain in less than 0. 002 mm.
