总结分析悬移质含沙量测量方法的代表性成果，评述各种测沙方法的适用性和突出优缺点。在此基础上，提出基于比热容原理测量含沙量的方法。该方法利用改制的比热容测量仪测定不同含沙量水体的比热容，建立含沙量与比热容之间的相互关系，进而通过测量浑水的比热容来确定水体含沙量。研究结果表明：水体含沙量与浑水比热容呈明显的负线性关系，可采用测量浑水比热容的方法来确定水体的含沙量；含沙量的测量精度与浑水比热容的测量精度密切相关。该方法从热学的角度研究水体的含沙量，旨在为泥沙动力学的研究提供新思路。

Suspended sediment concentration measurement methods are summarized, and the advantages and disadvantages of these methods are described in this paper. On this basis, a new method for sediment concentration measurement based on thermal capacity is put forward. Experiments were carried out to examine the relationship between the suspended sediment concentration and the thermal capacity of sediment-laden water. The results show a significantly negative linear relationship between the suspended sediment concentration and the thermal capacity of sediment-laden water. Thus, it is feasible to measure the suspended sediment concentration by measuring the thermal capacity of the sediment-laden water. Furthermore, the measurement accuracy of the suspended sediment concentration is closely connected to that of the thermal capacity. The sediment concentration measurement method introduced in this paper can provide a new way for sediment dynamics study from the perspective of thermology.
