【摘要】 固碳减排计量是进行减缓气候变化的碳交易机制的基础工作,而适合项目计量的计量方法学是实现交易的基础工具。我国正在大力推广的测土配方施肥项目在合理利用肥料、提高产量的同时,也表现出重要的农业温室气体的减排作用。为了给未来编制测土配方施肥方法学标准文本提供依据,本文从边界和基准线的设定、碳库和关键排放源的选取、固碳减排的计量方法等方面探讨了测土配方施肥项目固碳减排计量方法学问题。更多还原

【Abstract】 Recently carbon trading has been developed rapidly in the context of climate change mitigation. While quantifying carbon sequestration and greenhouse gases(GHGs) emission reduction is the basis for carbon trading, it is vital to develop the methodologies that offer great potential for the mitigation of climate change. The judicious use of fertilizers not only increases the production but also reduces greenhouse gas emissions and improves soil carbon storage at the same time. Carbon storage methods, along with the use of carbon trading were illustrated with regard to the setting of the boundary and baseline, the selection of carbon pool and key GHGs emission sources and measurement methods. The methodology to quantifying carbon sequestration and GHGs emission reduction could be used with the purpose to plan the recommended fertilizers application in future.更多还原
