摘要
利用Matlab数据库工具箱实现了对水文观测数据库数据的调用。基于日照海洋观测站10年实测资料,编程绘制了不同时段的波浪玫瑰图,比较分析了时段的长短对波浪玫瑰图绘制的影响。结果表明,日照港宜采用不少于5年的实测资料,由此绘制的波浪玫瑰图才能反映不同波级在各个方向上的长期变化趋势。
The allocation of observed hydrological data base is realized by utilizing Matlab Database Toolbox. On the basis of 10-year observed data, wave roses of different time length have been drawn with cumputer program. The effect of time length on wave rose drawing has been compared. Results show that no less than 5-year long wave data should be collected to draw wave rose which can reflect long change trend of wave frequency in different directions.
