解釋
洪水流量預報-
Combined with the significant project - gongboxia hydro - power station construction, emphasized on construction during flood period of power station construction period, the climate character of the upstream of yellow river basin and the practice operation state of cascade reservoirs are analyzed, some problems in construction during flood period such as flood propagation time, interval flood discharge forecast, construction risk, flood period pre - alarm and longyangxia reservoir ' s function on construction of gongboxia are also studied, with an aim at presenting real interval flood forecast scheme and dispatching method, so as to provide technological support for gongboxia hydro - power station construction period
本論文結合國家重點工程項目?公伯峽水電站的建設，以電站建設期施工渡汛為研究重點，從實施出發，分析黃河上游氣候特性和梯級水庫群的實際運行狀況，對施工渡汛中的主要問題?洪水流達時間、區間洪水預報、渡汛風險、汛期預警、龍羊峽水庫在渡汛中的作用等進行了比較全面深入的研究，目的在於提出可用於實際的區間洪水預報方案和調度方法，為公伯峽水電站施工期建設提供技術支撐。 -
Using flood progress model and the different discharge of feilaixia reservoir, we can calculate in time the water level and discharge of middle - lower reaches of beijiang, thus increase the accuracy of flood forecast and provide the important technical support for the further research on the optimal dispatch method of f lood control system
其中依據水文學和水力學相結合的洪水演進模型，可根據飛來峽水庫不同的下泄流量，及時計算北江中下遊河道的水面線和下泄流量，提高了洪水預報的精度，為進一步研究防洪體系優化調度方法提供極其重要的技術支撐。 -
Combining with case study, the application conditions of hydrologic meteorology forecast information and flood forecast information in dynamic control of the limit water level during flood seasons are also illustrated. ( 3 ) in order to relieve the contradiction between water discharge in flood seasons and water shortage after flood seasons, the manner of flood operation with fixed limited water level during fixed time should be adjusted
（ 3 ）為改變水庫汛期棄水而汛后又缺水的矛盾局面，調整現行水庫固定時間固定汛限水位的調度方式，利用短期氣象預報和洪水預報信息，在不改變現有防洪標準的前提下研究防洪預報調度方式，實現防洪與興利效益的轉換，提高洪水資源的利用率。
