我们总结了一个跨学科网络的工作，以探讨英国高地气候变化的影响。在这份CR特别报告中，撰稿人介绍了知识状况，本导言综合了这些知识，并为决策者提供了启示。高地是有价值的半自然栖息地，提供了历史上被认为是理所当然的生态系统服务。例如，泥炭土主要存在于高地，含有英国约50%的陆地碳。土地管理仍然是提供生态系统服务的驱动力。退化和管理的泥炭地容易受到侵蚀和碳损失，对生物多样性、碳储存和水质产生负面影响。英国高地已经经历了气候变化，并可能加剧这些压力。气候包络模型表明，到21世纪末，在低排放和高排放情景下，多达50%的英国高地和泥炭地将暴露在气候压力下。然而，有机土壤对这种气候压力的反应的基于过程的模型并没有给出一个一致的指示，这将意味着土壤碳：结果范围从非常轻微的增加，通过一个明显的下降，净碳损失。即使新的泥炭停止形成，保护现有的泥炭库存也是一项重要的气候缓解战略。保持高地植被覆盖是一项关键的双赢管理战略，将减少土壤碳的侵蚀和流失，并保护各种服务，如持续提供高质量的水资源。
We summarise the work of an interdisciplinary network set up to explore the impacts of cli- mate change in the British Uplands. In this CR Special, the contributors present the state of knowledge and this introduction synthesises this knowledge and derives implications for decision makers. The Up- lands are valued semi-natural habitats, providing ecosystem services that have historically been taken for granted. For example, peat soils, which are mostly found in the Uplands, contain around 50% of the terrestrial carbon in the UK. Land management continues to be a driver of ecosystem service delivery. Degraded and managed peatlands are subject to erosion and carbon loss with negative impacts on bio- diversity, carbon storage and water quality. Climate change is already being experienced in British Uplands and is likely to exacerbate these pressures. Climate envelope models suggest as much as 50% of British Uplands and peatlands will be exposed to climate stress by the end of the 21st century under low and high emissions scenarios. However, process-based models of the response of organic soils to this climate stress do not give a consistent indication of what this will mean for soil carbon: results range from a very slight increase in uptake, through a clear decline, to a net carbon loss. Preserving existing peat stocks is an important climate mitigation strategy, even if new peat stops forming. Preserving upland vegetation cover is a key win-win management strategy that will reduce erosion and loss of soil carbon, and protect a variety of services such as the continued delivery of a high quality water resource.
