摘要：对希腊色雷斯地区的维斯托尼斯湖年均来沙量进行计算。维斯托尼斯湖泥沙主要来源于科斯尼斯河，科姆帕斯投斯河和揣沃斯河流域。其流域中（山区部分）产沙面积达845平方公里。上述来沙量全部在湖区沉积。因此对维斯托尼斯湖22年内平均含沙量进行估算，并对前后两不同时期地形图（等高线轮廓）进行比较。引用降雨径流模型，土壤侵蚀模型和泥沙输运模型三个子模块对上述三个流域年平均含沙量进行数值计算。比较计算结果，发现估算结果与数值计算结果相近，对地形图的对比引用较为合理。

Abstract: In the present study, the mean annual sediment inflow into Vistonis Lake (Thrace, northeastern Greece) was calculated. The sediment quantity originates mainly from the basins of Kossynthos, Kompsatos and Travos (Aspropotamos) Rivers. The whole basin area (mountainous part) contributing to the lake amounts to about 845 km2. The above mean annual sediment quantity was compared with the mean annual sediment accumulation in the lake. The latter quantity was estimated from the mean annual decrease of the lake water volume for a period of 22 years, which was determined by means of older and newer topographic maps (isobath contours). For the calculation of the mean annual sediment yield at the outlets of the three above mentioned basins, a mathematical model consisting of three submodels was used: a rainfall-runoff submodel, a soil erosion submodel and a sediment transport submodel for streams. The comparison of the computational results by means of the mathematical model with the estimation results by means of the topographic maps is satisfactory and encouraging.
