- 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。 - The gullies are formed by the processes of infiltration - interflow - collapses . ( 2 ) in the slope with sand - loess , the major factors of water erosion are the rainfall intensity and rainfall amount of annual first rainfall . ( 3 ) in the region , the evolution processes of slope gully system results from alternative actions of sand deposition and water erosion
( 1 )有片沙覆盖的斜坡小区，径流量少,但径流含沙率大，坡沟的形成过程是：垂直渗流坡地潜流崩塌； ( 2 )在沙黄土斜坡小区，每年春末夏初降雨的强度及降雨量是决定坡面产沙量的关键因素； ( 3 )该区坡沟系统的形成发育是风沙沉积、风蚀与水蚀交替作用的结果。
