气候变化谈判中木质林产品的相关概念及其碳储量核算

Definitions and Carbon Stocks Accounting Approaches of Harvested Wood Products in Climate Change Negotiation

森林在维持全球碳平衡中发挥着重要的作用。采伐后木质林产品（harvested wood products,HWP）,以下简称木质林产品。木质林产品是森林资源利用的自然延伸。通过森林采伐和产品使用将森林固定的碳转移到产品中,但这部分碳在过去往往被忽略（Dewar,1990）。据估测。

Under the United Nations framework convention on climate change（UNFCCC）,all parties are required to report their greenhouse gas（GHG） emissions and removals.The carbon stocks of harvested wood products （HWP） are also a part of greenhouse gases （GHG） inventory.Forest harvest and wood product consumption play an important role in the carbon balance between forests and atmosphere.Consumption of wood products emits carbon,especially they are used in the landfill.However,the definitions and accounting approaches of HWP are still uncertainty.The implication of approaches applying in different countries is unclear.To impulse the ongoing international negotiation,this paper discussed the definitions and accounting approaches within the documents of UNFCCC and intergovernmental panel on climate change（IPCC） report,and also expanded the implication of HWP from a new position,which gave prominence to equity.In addition,this paper firstly put forward the new definition of carbon quality.
