Data underlying the publication Emerging forest-peatland bi-stability and resilience of European peatland carbon stores

Summary: Peatlands are sensitive ecosystems that store carbon and water and support biodiversity. Currently European peatlands are threatened by climate change and exploitation. With this model, we show that many landscape settings may support both wetland ecosystems on thick peat soils and forest ecosystems on thin organic soils. Both ecosystems have distinctly different water-carbon dynamics that create internal positive feedbacks allowing both ecosystems to co-exist (bistability), but also to shift when critical limits are exceeded.<br> Model scripts in R and input files to run the model for entire Europe. This requires almost 1,000,000 model runs of 1000Y each(5650 locations, 166 runs per location, estimated 1-5 minutes per model run, total output of around 85 Gig., not presented here)

摘要：泥炭地（Peatlands）是一类兼具碳储存与水分涵养功能的敏感生态系统，同时为生物多样性提供支撑。当前欧洲泥炭地正面临气候变化与开发利用的双重威胁。本研究依托该模型证实，诸多景观环境可同时支持厚泥炭土层上的湿地生态系统与薄有机土层上的森林生态系统。两类生态系统的水碳动态特征存在显著差异，可形成内部正反馈机制，使得二者能够共存（即双稳态）；而当临界阈值被突破时，生态系统状态也会发生转变。
本数据集包含用于运行全欧洲尺度该模型的R语言脚本与输入文件。该模拟需开展近100万次时长为1000年的模型运行（涵盖5650个研究点位，每个点位需进行166次模拟，单次模型运行预计耗时1至5分钟，总输出数据量约为85吉字节，完整结果未在此处展示）
