40年来，土壤管道首次被认为是流域水文响应的一个潜在因素，对其水文作用及其地理、气候和土壤分布的研究已经有了相当多的揭示。从英国到加拿大、印度和中国的现场实验表明，管道是支持地下流动可能是快速流动的重要贡献者这一假设的主要因素。这项研究表明，至少在某些地区，土壤管道可能贡献了近50%的雨水排放。因此，管道过程值得纳入降雨径流模拟模型，但这尚未实现。在管道流动本身的建模方面已经取得了一些进展，但是在集水区模型内的集成存在主要问题，尤其是在对管网的性质和分布进行量化或参数化方面。土壤管道的更广泛的环境影响也只是刚刚开始认识到。这些影响范围从停留时间变化对水化学的影响，特别是对地表水酸化的影响，到山坡排水模式对土壤发育和植被多样性的影响。版权所有©2010 John Wiley & Sons， Ltd
Over the 40 years, since soil piping was first considered to be a potential factor in the hydrological response of catchments, research has revealed a considerable amount about its hydrological role and its geographical, climatic and pedological distribution. Piping has been shown to be a major factor supporting the hypothesis that subsurface flow can be a significant contributor to quickflow by field experiments ranging from the United Kingdom to Canada, India and China. This research has demonstrated that, at least in some areas, soil pipes may contribute up to nearly 50% of stormwater discharge. Piping processes therefore merit inclusion within rainfall–runoff simulation models, but this has yet to be achieved. Some progress has been made in modelling pipeflow itself, but integration within a catchment model presents major problems, not least in quantifying or parameterizing the nature and distribution of pipe networks. The wider environmental implications of soil piping are also only just beginning to be recognized. These range from the effects of changing residence times on water chemistry, especially on the acidification of surface waters, to the effects of hillslope drainage patterns on soil development and vegetation diversity.
