太行山区人工油松林对坡面入渗产流的影响
Influence of Artificial Pine Forest on the Slope Run-off and Infiltration Characteristic in Taihang Mountainous Region
摘要
Abstract
The slope infiltration and run-off characteristics of artificial pine woodlands and bush-grass lands in Taihang mountainous region was studied by runoff plot experiments. The results showed that: The slope run-off was less and the infiltration was larger in two vegetation covers. The amount of run-off and infiltration were both increased with rainfall increasing. The amount of run-off and infiltration in pine forest plot was less than that in shrub and grass plot when the rainfall was small, but the run-off in pine forest was larger than that in shrub and grass plot when the rainfall was heavy, and the infiltration was still smaller. The outflow lasted longer in pine forest plot than that in shrub and grass plot in one precipitation process. The area of the peak flow and the flow amount of pine forest plot were both larger than that of shrub and grass plot in the high-intensity rainfall, the result was adverse when the rainfall intensity was low. It was the main reason that the soil moisture content was higher for a smaller precipitation infiltration, larger soil flow, longer flow duration and spike peak flow.关键词
