摘 要 ：借助于水文学对不同下垫面状态的产流模式研究的成果 ,建立了计算四湖流域两个调蓄湖泊汛期洪峰水位的模型。模拟分析的结果表明 ,在 4种同样的降雨条件下 ,景观结构变化使长湖汛期日水位平均增加 0 .0 831～ 1 .32 2 3m,最大增加 0 .1 5 79～ 1 .85 83m,使洪湖汛期日水位平均增加 1 .0 81 0～ 2 .30 0 8m,最大增加 1 .41 0 1～ 2 .4864m。证明景观结构变化是引起洪涝灾害加剧的重要原因且景观结构变化对湖泊洪峰水位的影响存在一种累加效应。景观结构的调整也是控制洪涝灾害的重要途径。

Abstract:The areas of forestry in the upper reach and lakes in the lower reach of many watersheds have been on the decrease, so the flood problem has become mo re frequent and worse in China. Great attention must be paid to research about t he effect of the changing landscape structure on the hydrological process of wat ershed.; The watershed in study here, Sihu watershed in Hubei, China, is a plain consisti ng of paddy field, fishpond, lake and dry land. There were different runoff-yie l d models for the four kin...
