Exploring the role of deadwood in the forest soil carbon cycle.

这将是第一次对英国不同林地类型的森林碳(C)循环进行此类研究；以及如何量化死木在环境和管理因素中的作用，控制死木供应、储存和损失的速度。森林研究需要关于枯木C循环的数据来提供证据，向其他人展示如何最好地管理森林以应对气候变化，因为森林从大气中去除二氧化碳(CO2)，并将其储存在生物质、枯木和土壤中。枯木为分解生物提供了食物，他们在生物量中固定了一些碳，并在下雨时将一些二氧化碳释放回大气，并将溶解有机碳(DOC)释放到流入土壤的水中。该项目将提供有关英国森林中有多少碳储存在枯木中，以及有多少碳以二氧化碳的形式流失到大气中或以DOC的形式转移到土壤碳库的基本信息。它将评估英国各地由于不同的环境条件，如树木类型、土壤类型、气候和大气污染，碳储存和枯木损失之间的平衡是如何变化的。所获得的工艺知识将用于开发森林碳模型的死木模块。这个模型将被用来进一步探索死木C循环是如何运作的，以及这种循环如何随着管理和环境条件的变化而改变。该项目的研究将帮助森林研究向森林管理者解释如何最好地管理枯木以应对气候变化

This will be the first study of its kind the forest carbon (C) cycle across different UK woodland types; and how to quantify the role of deadwood in environmental and management factors control the rate of deadwood supply, storage and loss. Forest Research need data on the deadwood C cycle to provide evidence to show others how to best manage forests to combat climate change, as forests remove carbon dioxide (CO2) from the atmosphere and store it biomass, deadwood and soil. Deadwood provides food for decomposer organisms, who fix some C in their biomass, and release some CO2 back to the atmosphere and dissolved organic carbon (DOC) to water flowing in to soils when it rains. This project will provide essential information about how much C is stored within deadwood in UK forests, and how much is lost to the atmosphere as CO2 or transferred as DOC to the soil C store. It will evaluate how the balance between C storage and loss from deadwood varies across the UK due to different environmental conditions, like tree type, soil type, climate and atmospheric pollution. Process knowledge gained will be used to develop a deadwood module for a forest carbon model. This model will be used to further explore how the deadwood C cycle works and how this could change as management and environmental conditions change. Research from this project will help Forest Research explain to forest managers how they can best manage deadwood to combat climate change
