By study, for hydrological characteristics and affecting factors of small basin, show that in a same meteorological area, the average annual rainfall of small basin could be determined combine with elevation distribution curve of the basin and its linear change rate of annual rainfall with elevation.
从研究小流域水文特性及其影响因素入手，提出了在同一气候区内，应用小流域高度分布曲线与年降雨量随高度呈线性变化关系，来确定小流域面平均年降雨量，并应用年降雨径流关系分解小流域不闭合的河床地下水潜流量，以提高无资料地区小流域设计径流的技术水平。
