Abstract : in accordance with the problems in the system of well storing rainfall at present , based on the experiments of artificial simulating rainfall , and assistance with the measures of natural rainfall , the relationships among the surface runoff yield , silt concentration , catching runoff efficiency and the material of surface , slope gradient , rainfall intensity are analysed systematically . then , the best slope gradient and material of surface are chosen , in condition of which surface rainfall yield is the largest and silt concentration is the smallest . this is a beneficial study for the practical use of the rainwater catchment plot in furture
文摘:针对当前旱井集雨系统存在的问题，利用人工降雨试验，并辅以天然降雨观测，系统分析了旱井集流区的产流量、含沙率、集流效率与下垫面材料、坡度、降雨强度的关系，进而选出了最优坡度及最优下垫面材料，为今后旱井集流区的应用研究做了有益的探讨。
