摘　　要：本文提出了在已知被测泥沙比重条件下,通过测量集流桶内浑水体积与质量后,联立数学方程组计算含沙量的一种方法;分析了该测量方法的主要误差来源;在径流小区产沙量两年的观测试验中,利用传统方法(烘干称重法)对该方法进行检验校准结果及大量的试验研究数据表明,该方法准确可靠、简单易行,可广泛适用于泥沙质地均匀、石砾、碎石含量较少的地区。最后提出了该测量方法的展望。A method for calculating sediment concentration by means of simultaneous mathematical equations after measuring the volume and mass of muddy water in the collector barrel under the condition of known sediment specific gravity is proposed.The main error sources of the measurement method are analyzed;In the two-year observation test of sediment yield in runoff plots,the traditional method(drying weighing method) was used to check and calibrate the method and a large number of experimental data showed that the method was accurate,reliable,simple and feasible,and could be widely applied in areas with homogeneous sediment texture,less gravel and gravel content.Finally,the prospect of this measurement method is put forward.
