| 摘 要： | 采用实测资料分析、数模计算和比尺模型试验等手段,研究比较尖山河段顺直和弯曲两种河势对钱塘江河口上游河床冲淤、潮汐、潮流、涌潮、盐水入侵等重要环境因子的差异.从钱塘江河口治理“减少进潮量、增大山潮水比值”的原则及多目标综合开发治理的目标和消除治理过程中已出现的不利因素考虑,应该采取弯曲河势更为有利.

| Abstract: | Based on the analysis of field observation data, the mathematical calculation and the physical modeling, this paper studies and compares effect of the meandering channel and straight channel evolved in the Jianshan bend on the important environmental factors such as riverbed variation in the upper reaches of Qiantang Estuary, tide, current, tidal bore and salt water intrusion etc.It is more reasonable to adopt the meandering alignment according to the principle of reducing tidal influx and raising the ratio between river flow and tidal discharge, overall development of the multiple purpose, and eliminat ing the unfavorable factors which was shown in harnessing process of Qiantang Estuary. |

| Keywords: | strong tide estuary straight and meandering channel environmental effect Qiantang Estuary |
