以往的河道规划都是以安全下泄洪水流量为目标的。除防沙区间、水库等河流泥沙输移较多的特殊情况之外, 河道内泥沙的输移, 一般在河道规划中未予考虑。随着河道整治的进展, 洪水下泄能力也逐渐提高, 但由于对泥沙输移带来的种种现象未予充分考虑, 故在控制水土流失的过程中, 防洪、兴利、环境问题越来越突出。这表明, 如果不是从河流规划阶段起就对流量和输沙量进行整体性研究, 从综合性考虑, 就不能创造一个健全的河流。文章就河道泥沙管理、今后河流治理应注意的课题进行了论述。
All previous river programs targeted flood discharge safely. In addition to special circumstances such as sand control areas and reservoirs where there is more sediment transport in the river, sediment transport in the river channel is generally not considered in river channel planning. With the progress of river regulation, flood discharge capacity has also gradually increased, but due to various phenomena caused by sediment transport did not give full consideration, so in the process of controlling soil and water loss, flood control, Xing, more and more environmental issues prominent. This shows that without a holistic study of flow and sediment transport from the river planning stage, a sound river can not be created from a comprehensive perspective. The paper discusses the problems of river sediment management and future river management.
