Abstract Forest thinning has been used as a management tool to reverse the adverse impacts of decades of fire suppression in the western USA. Research into the impacts of thinning on surface water, soil, and vegetation re-growth have occurred concurrently with the growing popularity of forest thinning; however, its potential impact on groundwater recharge and related springs ecosystems has largely been ignored until recently. This systematic review provides an overview of some of the tools used to measure the influence of forest management on groundwater recharge, including numerical and process based modeling, empirical paired-watershed approaches, and statistical stochastic techniques. A brief discussion of the benefits and drawbacks of each method also is provided. The paper provides a literature review of existing studies of groundwater recharge and forest management from 1971 to 2018. The review of 35 studies indicates a range of results and highlights differences between studies of clear-cut forests versus thinned forests. Forests that were thinned had a greater amount of groundwater recharge than clear-cut forests, indicating that recharge responds positively and more strongly to reduced sublimation and evaporation in partially thinned forests than to clear-cut removal of mature trees. A similar test with forest encroachment studies revealed no differences between forest encroachment and either thinning regime. The number of forest management-groundwater recharge studies has dramatically increased over the last two decades, indicating increased interest in finding tools to increase groundwater yields for societal use in rapidly populating aridland forests. To our knowledge there have been no studies of forest thinning impacts on springs ecosystems, a field of study rich with possibilities for ecologists, hydrologists, rangeland and forestry scientists, and interdisciplinary ecohydrology practitioners.

林分间伐对旱地森林地下水补给的影响

摘要 森林间伐已被用作一种管理工具,以扭转美国西部数十年灭火的不利影响。随着森林间伐日益流行,对间伐对地表水、土壤和植被再生长的影响的研究也在进行;然而,直到最近,它对地下水补给和相关泉水生态系统的潜在影响在很大程度上被忽视了。本系统综述概述了一些用于衡量森林管理对地下水补给影响的工具,包括基于数值和过程的建模、经验配对流域方法和统计随机技术。还简要讨论了每种方法的优点和缺点。该论文对 1971 年至 2018 年地下水补给和森林管理的现有研究进行了文献回顾。 对 35 项研究的回顾表明了一系列结果,并突出了对砍伐森林与稀疏森林研究之间的差异。与砍伐森林相比,被砍伐的森林具有更多的地下水补给量,这表明补给对部分砍伐森林中升华和蒸发减少的响应比对成熟树木的砍伐更积极和更强烈。对森林侵占研究进行的类似测试显示,森林侵占和任何一种间伐制度之间没有差异。在过去的二十年中,森林管理-地下水补给研究的数量急剧增加,表明人们越来越有兴趣寻找工具来增加地下水产量,以供社会在快速人口稠密的干旱森林中使用。据我们所知,还没有关于森林变薄对泉水生态系统影响的研究,这是一个为生态学家、水文学家、牧场和林业科学家以及跨学科生态水文学从业者提供丰富可能性的研究领域。
