摘要
简单介绍了计算流域面雨量的泰森多边形法和逐步订正格点法 ,并运用此两种方法及气象站资料的算术平均法与气象站和水文站资料的算术平均法计算了 1 998年 ( 5~ 9月 )、1 999年 ( 5~ 9月 )及 2 0 0 0年 ( 5~ 8月 )湖南 5个小流域的实况面雨量。从整体上看 ,几种方法的计算结果均无显著差异 ,但不同方法所得面雨量的逐日差异有的还是相当明显的。
The methods to calculate the river valley area rainfalls, such as Thiessen polygon method and successive correction method are introduced, and actual area rainfalls of five small valley areas in Hunan in 1998(May-Sep.),1999(May-Sep.) and 2000(May-Aug.) are respectively computed by these methods and arithmetical average method.As a whole, there is not notable difference,but there is a great diversity of area rainfalls day by day using different methods.
