中文摘要	砂田是一种具有综合效能的旱作技术,在干旱半干旱地区得到了不同程度的应用。为了研究砂石覆盖下降雨入渗的规律,进行了室内模拟实验,对土壤水分的动态变化过程进行了研究。结果表明:在模拟降雨过程中,砂石覆盖下土壤的累计产流量一直低于裸土,说明砂石覆盖有利于减少土表降雨产流。砂石覆盖的土壤的各个深度土壤含水率均比裸土对照组要高,表明砂石覆盖有降雨入渗到土壤中。在经过一定时间的降雨后,砂石覆盖土柱中不同深度的土壤含水率变化会趋于稳定,且数值接近,表明砂石覆盖的土壤比裸土更快地进入稳渗阶段。
英文摘要	Sandy field farming was a comprehensive effective technology of drought-resistant,which had been utilized in arid or semi-arid regions to vary degrees.The author presented the results of the laboratory simulating experiment conducted to investigate the process of rainfall infiltration of soil under sand and gravel mulch.The results showed that the accumulated runoff of soil under sand and gravel mulch was always higher than the one without mulch during the simulated rainfall process.It indicated that the sand and gravel mulch was propitious to reduce the covered soil surface rainfall runoff.The values of soil moisture in the soil layers with mulch at different depths were higher than those without mulch.This showed that the sand and gravel mulch could increase infiltration amounts.After a certain period of time of rainfall,the values of soil moisture with mulch at different depths would stabilize,and the values were close to each other.The soil covered with mulch would be faster than the bare soil into the steady infiltration stage.
