| 摘要: |
| 利用千河千阳水文站1957～1993年的水沙资料及冯家山水库的运用方式，建立了冯家山水库淤积数学模型。在数学模型验证的基础上，得到了冯家山水库未来50年内的淤积过程、淤积总量及分布。其中水库将淤积1.71 亿m3，推移质淤积占0.259 亿m3,悬移质淤积占1.45 亿m3；有效库容由2.86 亿m3损失到1.43 亿m3，死库容由0.91 亿m3损失到0.33 亿m3,而导致冯家山水库调节系数降低，大大减小调节能力。 |

| Abstract: |
| This paper utilizes water and sediment data which collected from Qianyang hydrologic station from 1957-1993 and the administrated model of Fengjiashan Reservior, the authors constructe Abstract: methematic model of reservior deposition.Based on the check of the model,the authors research on the process,quantities and distribution of the deposition in fifty years in the future.Total deposition in the reservior is 171 millions 3 ,bed material is 25.85 millions 3,suspending sediment is 145 millions 3.Effective storage will decrease from 286 millions 3 to 143 millions 3,died storage will decrease from 91 millions 3 to 33 millions 3.It will lead to the decrease of coeffient of the reservior and reduce the capability of adjusrment greatly. |
