Assessing the structure and function of peatland ecosystems in a changing environment

加拿大泥炭地储存了约5%至10%的陆地碳。到目前为止，它们代表着加拿大最大的碳库。它们是小型但持久的全球重要二氧化碳汇，也是大气CH4的中等全球重要来源。泥炭地碳是全球气候变冷的结果。泥炭地作为大气碳的加工者和储存地的生态和生物地球化学功能与水的储存有关。在全球碳循环中，北部地区的泥炭地覆盖率为30%-100%，这取决于它所在的位置，因此对气候的调节具有全球意义，这导致各国政府(如安大略省)制定立法，目的是维持“碳储存和封存”。“北方”地区的气温上升幅度将高于平均水平，生态系统中的蓄水量可能会减少。由于土地利用的变化，预计北方将面临越来越大的压力。

Canadian peatlands store about 5 to 10% of all terrestrial carbon. They represent , by far, the largest carbon reservoir in Canada. They are small but persistent globally significant sinks for CO2 and a moderate globally significant source of atmospheric CH4. Peatland carbon is a cooling effect of global climate. The ecological and biogeochemical function of peatlands as processors and stores of atmospheric carbon is linked to water storage. The global significance of the boreal region, which has 30 - 100% coverage of peatlands depending on location, in the global carbon cycle and, hence regulation of climate, has lead governments (e.g. Ontario) to introduce legislation whose objective is to maintain 'carbon stores and sequestration'. The 'north' will experience greater than average increases in temperature and water storage in ecosystems is likely to be reduced. It is also expected that the 'north' will experience increasing pressures due from land-use change due
