| 摘 要： | 在实施一个大型国际合作项目（ＢＩＴＥＸ ’９３）期间，作者在琵琶湖进行了一个大规模的内波野外观测．９台垂直系留的湖流观测及其旋转谱分析的结果表明：除了众所周知的开尔文波以外，在表层有风的日变化造成的周期为２４ｈ的顺时针旋转的强迫振荡，在温跃层，Ｐｏｉｎｃａｒｅ波的第一调式（ｍｏｄｅ）占主导地位．Ｐｏｉｎｃａｒｅ波使温跃层附近的湖流以周期１６－１８ｈ顺时针旋转，在底层，周期为１１ｈ的不旋转的重力波非

| Abstract: | In the light of storm flood properties, analysis and computation ave carried out about four heavy flood events ever occurred in the Poyang Lake area using four mbthods, i.e.area ratio method, adjusted total inflow method, tingle-source model(the current flood forecasting scheme) and the Xin'anjiang Model(three-source), for the sake of river basin flood control planning The effect of the changing ratios of water surface to land surface corresponding to diferent water stag-es on i.e off generation and flow concentration is analyzed.and the estimation formulae in the Xin'an jiang Model are modified.Results show that conceptual rainfall-run of models can properly simulate the flood processes, and that under reasonable conditions, simplified methods can also prod uce satisfied results.The applicability co nditions of different methods are given through com-parative analysis. |
