The carbon sequestration potential of peatlands has led to increasing interest in the restoration of bogs previously subjected to plantation forestry. However, little information exists about the effects on hydrological processes of what has become known as forest-to-bog restoration. The hydrological functioning of three afforested, two intact and four forest-to-bog restoration sites was compared at a raised bog and blanket bog location. For the raised bog location, the annual runoff/rainfall coefficient was 59.7% for the intact site, 41.0% for the afforested site and 53.1% for the oldest restoration site (9 years post-felling). At the blanket bog location, the coefficient was 80.6% for the intact site, 63.0% for the afforested site and 71.6% for the oldest restoration site (17 years post-felling). Compared with intact bog, median peak storm discharge was significantly greater in the restoration sites for the raised bog location but not for the blanket bog location. Water-table peak lag times were greatest, and water-table depths deepest in the afforested sites and the most recent raised bog restoration site and least in the oldest blanket bog restoration site. The estimated contribution of overland flow in the afforested sites was 2.9% for the raised bog and 11.9% for the blanket bog, increasing to 8.7% and 32.2% at the oldest restoration sites for the raised bog and blanket bog, respectively. Overall, hydrological functioning of the raised bog and blanket bog restoration sites was different from the intact sites but was most similar to intact bog in the oldest restoration sites.

森林到沼泽恢复对凸起沼泽和毯状沼泽水文功能的影响

泥炭地的固碳潜力导致人们对恢复以前用于人工林的沼泽越来越感兴趣。然而，关于森林到沼泽恢复对水文过程的影响的信息很少。在凸起的沼泽和毯状沼泽位置比较了三个绿化、两个完整和四个森林到沼泽恢复地点的水文功能。对于凸起的沼泽地，完整场地的年径流/降雨系数为 59.7%，绿化场地为 41.0%，最老恢复场地（砍伐后 9 年）为 53.1%。在毯式沼泽地，完整场地的系数为 80.6%，绿化场地的系数为 63.0%，最老恢复场地（砍伐后 17 年）的系数为 71.6%。与完整的沼泽相比，在凸起的沼泽位置的恢复地点，风暴流量的中值峰值明显更大，但在毯式沼泽位置则不然。地下水位峰值滞后时间最大，水位深度在绿化点和最近凸起的沼泽恢复点最深，在最古老的毯状沼泽恢复点最小。造林地点的地表径流对凸起沼泽的估计贡献为 2.9%，对毯状沼泽为 11.9%，在最老的恢复地点，凸起沼泽和毯状沼泽分别增加到 8.7% 和 32.2%。总体而言，凸起沼泽和毯状沼泽恢复点的水文功能与完整站点不同，但与最古老恢复站点的完整沼泽最相似。
