Replication Data for: Effect of Controlled drainage on cultivated peatsoil in Finland

This data provides the carbon balance of drained peatland under controlled drainage during the growing season in 2016 in Mouhijärvi, Southwestern Finland. The CO2 fluxes measured with a transparent chamber method were divided into gross primary productivity (GPP) and ecosystem respiration (ER) for modelling based on environmental factors (light and temperature) and canopy reflectance (leaf area index, LAI). The GPP model estimates the effect of light and vegetation status, whereas the ER model captures the share of foliar biomass-dependent respiration and the ground water table.本数据集涵盖芬兰西南部穆赫耶尔维（Mouhijärvi）地区2016年生长季内，受控排水工况下疏干泥炭地的碳平衡数据。采用透明箱法测定的二氧化碳（CO₂）通量被划分为总初级生产力（Gross Primary Productivity, GPP）与生态系统呼吸（Ecosystem Respiration, ER），并基于环境因子（光照与温度）及冠层反射率参数（叶面积指数，Leaf Area Index, LAI）构建相应模型。其中总初级生产力模型用于量化光照与植被状态的影响效应，而生态系统呼吸模型则可表征受叶片生物量调控的呼吸占比与地下水位的关联关系。
