Evaluating the success of fen creation in the post oil sands landscape

在Fort mcmult附近的油砂开发地区，泥炭地占了地形的65%。超过250平方公里的油砂开采扰乱了这些泥炭地的大片土地，需要重新开垦以维持正常的自然生态系统。从本质上讲，沼泽泥炭地必须由从新租赁区拖来的沼泽泥炭形成，并与一个分水岭一起设计，以提供必要的水和溶解的矿物质，从而形成一个自我维持的生态系统，该生态系统可以积累碳，能够支持具有代表性的物种组合，并能够适应非周期性压力。这是以前从未尝试过的。除了帮助Suncor Energy遵守其法律义务，在开采后的景观中回收沼泽，这项研究对于理解设计含义，从而开发更优化的设计和更具成本效益的协议至关重要。汾河建设的根本问题是设计一个地下水系统，以支持维持水文、生物地球化学和生态过程所需的流入

In the oil sands development areas near Fort McMulTaypeatlands comprise up to 65% of the landscape. Oil sands mining of over 250 km2 disturbs large tracts of these peatlands, which require reclamation to a functioning natural ecosystem. Essentially, a fen peatland must be created from fen peat bOlTowed from new lease areas, along with a watershed designed to supply the requisite water and dissolved minerals that result in a self-sustaining ecosystem that is carbon-accumulating, capable of supporting a representative assemblage of species and resilient to nonnal periodic stresses. This has never before been attempted. In addition to assisting Suncor Energy comply with its legal obligation to reclaim fens in the post-mined landscape, this research is essential to understanding design implications and thus to the development ofmore optimal designs and cost-effective protocols. The fundamental problem for fen construction is to design a groundwater system that can support the inflows required to sustain the hydrological, biogeochemical and ecological processes and
