本文以幂函数y=ax~b摸拟土壤颗粒累积曲线,并以实测的质地资料验证了该模型的应用效果是理想的。这一模型的应用为苏、美制质地的转换提供了方便,从而使我们能够应用现有大量的苏制质地资料为土壤可蚀性因子K值的查算提供0.002～0.1mm和0.1～2.0mm粒级的百分含量资料。
In this paper, the cumulative curve of soil particles is simulated by the power function y = ax ~ b, and the experimental results show that the application of this model is ideal. The application of this model has facilitated the conversion of the texture of the Soviet Union and the United States so that we can apply the available data of the Soviet soil texture to provide 0.002-0.1 mm and 0.1-2.0 mm for the calculation of the soil erodibility factor K value Particle size information.
