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

这将是第一次对不同英国林地类型的森林碳(C)循环进行研究；以及如何量化枯木在环境和管理因素中控制枯木供给率、储存量和损失率的作用。森林研究需要有关枯木C循环的数据，以提供证据，向其他人展示如何最好地管理森林以应对气候变化，因为森林可以从大气中清除二氧化碳，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，这些生物在其生物量中固定了一些碳，并将一些二氧化碳释放回大气，并在下雨时将溶解的有机碳（DOC）释放到流入土壤的水中。该项目将提供有关英国森林枯木中储存了多少碳的基本信息，以及有多少碳以二氧化碳的形式流失到大气中，或以DOC的形式转移到土壤中储存碳。它将评估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，英国各地枯木碳储量和碳损失之间的平衡是如何变化的。获得的过程知识将用于开发森林碳模型的枯木模块。该模型将用于进一步探索枯木C循环是如何工作的，以及它如何随着管理和环境条件的变化而变化。该项目的研究将帮助森林研究中心向森林管理者解释他们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
