本文首先概述了黄、渤海的风和浪基本情况,根据国家海洋局、渤海沿岸8个典型台站26～30年的波浪实测资料,进行了波浪年极值统计分析,选用三参数Pearson—Ⅲ型分布及四参数指数Γ分布两种线型,并用最小二乘法与优选法相结合的寻优适线法(FIT)对分布参敬进行估计,从而得出黄、渤海8个典型台站不同重现期的设计波要素。研究表明四参敬指敬Γ分布比三参数Pearson—Ⅲ型分布适线的弹性更大,对经验频率的拟合精度更高。但两种分布的计算结果相差不大。本文为水利部技术开发基金项目“中国沿海风浪统计分析”第二阶段研究报告。

The basic wave and wind conditions in the yellow Sea and the Bohai Sea are presented in the paper. On the basis of the observed wave data obtained in the last 26 to 30 years from 8 typical observation stations along the coasts of the Yellow Sea and the Bohai Sea by the National Bureau of Oceanography, a statistical analysis of annual ultimate values of waves is made, using the three-papameter Pearson-Ⅲ curve and ther distribution of four-papameter index, and the distribution parameters are estimated with the FIT method combining the least square method and the optimization method, thus, establishing the design wave characteristics in different recurrence intervals at the 8 observation stations along the coasts of the Yellow Sea and the Bohai Sea. Results of the study have shown that the r distribution of four-parameter index is more elastic than three-parameter Pearson-Ⅲ distribution curve and has a higher fitting accuracy for empirical frequency though there is no significant difference between the computed results of the two distributions. This paper is the research report for the second stage of the "Statistical Analysis of Winds and Waves along China's Coasts" a project sponsored by the Technical Development Foundation under the administration of the Ministry of Water Resources and Electric Power.
