东天山地区暴雨衰减指数的推算

CALCULATION OF ATTENUATION INDEX OF RAINSTORMS IN THE EASTERN TIANSHAN MOUNTAINS

为了探索出哈密地区暴雨衰减指数n值的合理定量，提高设计洪水的精度，首次以哈密、巴里坤站37年自记雨量资料，推求暴雨衰减指数n值．以供小面积（100km2以下）河沟的设计洪水使用．

In order to approach the rational values of attenuation index (n) of rainstorms in Hami region and improve the designing precision for flood control, the values of attenuation index (n) are firstly calculated based on the 37-year rainfall data recorded by pluviographs at Hami Metcorological Station and Barkol Meteorological Station, which can be used for designing the flood control works for small basins (below 100 km2).
