摘要

在红壤丘陵区，对自然降雨条件下坡地（上层0～40cm，下层40～110cm）降雨壤中流产流过程进行了研究，结果表明：不同土地利用方式下，油茶林壤中流产流量大于同层恢复区；壤中流峰值流量恢复区大于同层油茶林；油茶林壤中流产流过程较恢复区开始早、结束晚。随着土层加深，滞后时间延长。同一土地利用方式下，产流量、峰值流量、滞后和拖尾均为上层小于下层。壤中流对降雨及地表径流的响应均为上层快于下层。不同的降雨类型，壤中流产流机理不同。峰值型降雨壤中流产流过程滞后时间较小，壤中流产流类型多为驱赶流。

Abstract

This text study the natural rainfall-interflow processes uplayers(0~40 cm) and downlayers(40~110 cm) in red soil hilly region.The results showed: the interflow flux in oiltea camellia is more than that in resumed field with different land use modes

but the peaks flux is oppositional.The rainfall-interflow processes begin is better early and close is later in oiltea camellia than that in resumed field.The laggard duration time increase with soil layers depth increasing.The values of interflow flux

peak flux

laggard duration and prolonged duration at uplayers are less than that at downlayers.The uplayers interflow proceed in answer to runflow is sooner than that of downlayers.Most interflow occurring causes is different with different kinds of rainfall.The laggard duration time is shorter in peak rainfall processes than others.Most interflows are driving-flow.
