ABSTRACT

The protection of ecological functions of forested swamps and peatlands is the subject of legal and regulatory measures. In Quebec and elsewhere in Canada, wood harvesting is carried out on swamps and peatlands of merchantable forests. What is the impact of forestry practices on these wetlands hydrological functions such as sediment retention, groundwater recharge, flood reduction and low flow augmentation? The answer to this question is complex as the contribution of wetlands to these hydrological functions vary with each wetland type as underlined by the experts. With the aim of ascertaining the contribution of wetlands, and to infer the effects of forest management on forested swamps and peatlands, we carried out a literature review. The existing literature reviews only partially cover the subject or in the case of peatlands, they mainly consider drained sites. In this review, the links between the hydrologic functions and forest harvesting are treated by category of wetlands to take into account their anticipated specific contribution.

抽象的

保护森林沼泽和泥炭地的生态功能是法律和法规措施的主题。在魁北克省和加拿大其他地方，木材砍伐是在可商购森林的沼泽和泥炭地上进行的。林业实践对这些湿地水文功能（如沉积物保留，地下水补给，减少洪水和流量增加）有什么影响？这个问题的答案很复杂，因为专家强调，湿地对这些水文功能的贡献因每种湿地类型而异。为了确定湿地的贡献，并推断森林管理对森林沼泽和泥炭地的影响，我们进行了文献综述。现有文献评论仅部分涵盖了该主题，或者就泥炭地而言，他们主要考虑排水的地点。在这篇综述中，水文功能与森林采伐之间的联系按湿地类别进行了处理，并考虑了它们的预期具体贡献。
