摘要
利用逐日降雨资料，设计了单站降雨集中期、集中度的公式，进而制定了单站洪涝指数，并从洪涝程度和面积两个方面确定了反映大范围洪涝程度的洪涝指数。上述洪涝指数比较客观，有时空对比性，而且可由计算机算出。最后以50OhPa关键区高度作因子做了预报试验。
Using the daily rainfall data, we have designed formulae of concentrating period and concentrating degree of the precipitation in a station, and established the flood index for one station, According to the degree and the area of flood, then, we designed the flood index for large area. This kind of index is objective. It can be compared in time and in space field, and can be calculated by computer.
