摘要： 目前,对土壤水运移机理研究已从定性走向定量、从均质走向非均质。优先流是地下水入渗的普遍现象,在田间土壤水主要以捷径流方式入渗补给地下水。对优先流研究是潜水入渗补给研究的重点与难点之一,其主要方法为染色示踪与X射线成像和地质雷达技术。潜水入渗补给评价方法众多,且每种方法都有其适用条件。因此,综合采用示踪法、地下水位波动法、地中渗透仪法、零通量法和数值模拟法,相互对比验证,提高评价可靠性,是研究地下水入渗补给最有效的方法。

Abstract: Soil water infiltration is a main approach of groundwater recharge for the unconfined aquifers. Research on the mechanism of soil water transport has transferred from perspectives of qualitative to quantitative, and from homogenous to heterogeneous. Preferential flow is a prevalent phenomenon of groundwater recharge, which indicates that soil water infiltrates into the unconfined aquifers in the way of shortcut flow. Research on preferential flow is an important and difficult topic, with dyeing tracing, x ray microtomography and ground penetrating radar as main methods. Many of methods, e.g., tracing, groundwater level fluctuation, lysimeters, zero flux plane and numerical model, for the evaluation of groundwater recharge, are used in different conditions, therefore, we advise that the groundwater recharge is evaluated using several methods together by comparison and verification to improve assessment reliability.

Key words: unconfined groundwater, soil water, preferential flow, infiltration, recharge
