摘要
利用人工模拟降雨试验研究不同覆盖材料对降雨入渗能力的影响 ,重点研究渗水地膜覆盖、海绵薄膜覆盖情况下径流量和水分入渗速率的变化。结果表明 ,渗水薄膜覆盖、海绵薄膜覆盖均能明显降低径流量 ,增加水分入渗速率 ,海绵薄膜覆盖和渗水薄膜覆盖 2 4 min内的累积径流量分别减少 6 3.94 %和 87.0 8%。
A rainfall simulation experiment was carried out to assess the effect on infiltration that covered with different materials. This study focused on the runoff and the change of water infiltration rate, which is under the condition of water penetration and sponginess. The results showed that water penetration and sponginess could decrease the runoff 63.94%and (87.08%) respectively, but increase the water infiltration rate.
