【摘要】 短历时暴雨是晋西黄土丘陵沟壑区的主要雨型,也是造成该类型区严重土壤侵蚀最主要的动力因素。本文通过对王家沟流域44年(1955年～1970年,1974年～2001年)间的单站汛期自计雨量资料对当地短历时暴雨进行了分析,推导出了短历时暴雨重现期经验公式,为深化水土流失规律研究,验算天然降雨重现期,制订流域综合治理规划与水土保持工程设计提供科学依据。更多还原

【Abstract】 The storm with a short period of time is major type of rain in the Loess hilly and gully district, west part of Shanxi Province, it is key factor of power to make serious soil erosion. The storm with a short period of time has been analyzed according to the data of 44 years in the Wangjiagou Watershed in this paper, the experience equation about i value has been working out. It is a basis for designing engineering, planning of soil and water conservation and so on.更多还原
