印度尼西亚泥炭地的土地利用变化导致全球人为温室气体排放。需要可靠的预测工具来估计这种土地利用变化下泥炭土可能的土壤碳(C)损失和二氧化碳(CO2)排放。在热带泥炭地的研究和建模工作是有限的,限制了复杂的土壤模型参数化和评估的数据的可用性。热带泥炭地种植园碳评估工具(TROPP-CAT)的开发旨在提供一个用户友好的工具来评估和预测热带泥炭土壤的碳损失和CO2排放。该工具需要简单的输入值来确定沉降速率,其中氧化比例导致CO2排放。本文介绍了模型的结构和方程,并提出了一些评估和应用运行。TROPP-CAT已被应用于特定地点和国家一级的模拟,对现有的油棕榈andAcacia种植园,以及泥炭沼泽森林网站,以预测未来土地利用变化可能产生的排放量。通过不确定性和敏感性分析,文献综述和与其他方法的比较,估计土壤碳损失,本文确定了未来的模型开发的机会,不同的方法之间的桥梁,以预测CO2排放量从热带泥炭地土地利用变化。TROPP-CAT可从以下网址在线访问 www.redd-alert.eu 英语和印度尼西亚语。
Land use change on Indonesian peatlands contributes to global anthropogenic greenhouse gas (GHG) emissions. Accessible predictive tools are required to estimate likely soil carbon (C) losses and carbon dioxide (CO2) emissions from peat soils under this land use change. Research and modelling efforts in tropical peatlands are limited, restricting the availability of data for complex soil model parameterisation and evaluation. The Tropical Peatland Plantation-Carbon Assessment Tool (TROPP-CAT) was developed to provide a user friendly tool to evaluate and predict soil C losses and CO2emissions from tropical peat soils. The tool requires simple input values to determine the rate of subsidence, of which the oxidising proportion results in CO2emissions. This paper describes the model structure and equations, and presents a number of evaluation and application runs. TROPP-CAT has been applied for both site specific and national level simulations, on existing oil palm andAcaciaplantations, as well as on peat swamp forest sites to predict likely emissions from future land use change. Through an uncertainty and sensitivity analysis, literature reviews and comparison with other methods of estimating soil C losses, the paper identifies opportunities for future model development, bridging between different approaches to predicting CO2emissions from tropical peatlands under land use change. TROPP-CAT can be accessed online from www.redd-alert.eu in both English and Bahasa Indonesia.
