黄河河口延伸对下游淤积影响大小的问题是黄学研究中的一个争论焦点。在这个问题上,一部分学者认为河口完全控制下游淤积,一部分则认为河口只影响下游很短的距离,也有人认为在河口长期的延伸中,溯源淤积的范围将远远超过河口,和沿程淤积相结合,促使黄河下游河床平行抬升,争论不休。我们认为后一种认识在定性上是正确的,但需要对沿程淤积与溯源淤积进行过程上的定量分割。本文主要在这方面作了一些尝试。
The issue of the extent of the extension of the Yellow River estuary to the sedimentation in the downstream area is the focus of debate in the study of yellow water. On this issue, some scholars think that estuaries fully control the siltation in the lower reaches, and some think that estuaries only affect a very short distance downstream. Some people think that in the long-term extension of the estuary, the scope of traceable sedimentation will far exceed that of estuaries and sedimentation Combined to promote the lower reaches of the Yellow River uplift in parallel, arguing endlessly. We think the latter kind of understanding is qualitatively correct, but there is a need for a quantitative segmentation process along the siltation and traceability. This article mainly made some attempts in this respect.
