摘　　要：在建立河道冲淤测量断面空间模型的基础上,列出了断面间距的一些推算方法并探讨了解析计算程序,评述了断面间距各推算方法的特性及有关问题,在工程实践中推荐应用容积等效概化断面间距。After establishing a spatial model for the survey of sedimentation between cross sections in natural rivers, the various methods for calculating the distance between cross sections are discussed and their disadvantages and advantages are assessed respectively. Finally the method based on the equivalent volume principle is suggested to calculate the generalized distance between cross section in natural rivers
