摘　　要：以坡面研究为突破口，以黄河中游水沙规律为依据，以成因分析为基础，提出了“以洪算沙”的计算方法，并应用于河龙区间南片坡面措施分析中，结果表明较为可行合理。该研究方向在方法论上是有益的探索，在理论和实践上具有广阔的研究前景。Taking slope research as a breakthrough point,according to the variation law ofrunoff and sediment in the middle reaches of Yellow River and on the basis of cause and effectanalysis,proposes″calculating sediment by flood″method,and apply this method to the slopemeasures analysis of the south watershed between Hekou and Longmen. The results show thatthe method is relatively reasonable, this study direction is a kind of useful exploration to method-ologly and has broad research prospects for the theory and practice.
