中国省级土地利用变化和林业温室气体清单编制方法

The Methodology of Provincial Greenhouse Gases Inventory in Land Use Change and Forestry Sector

省级土地利用变化和林业(LUCF)温室气体清单主要评估"森林和其他木质生物质生物量碳储量的变化"和"森林转化温室气体排放"两类主要温室气体的排放源或吸收汇。省级LUCF温室气体清单编制方法以政府间气候变化专门委员会(IPCC)有关国家温室气体清单指南为基础,结合中国LUCF活动的实际情况,特别是在考虑核心关键数据的可获得性与可靠性的基础上制订完成。同时还建立了适用于不同省的关键排放因子和参数数据库,旨在为科学合理地编制中国省级LUCF温室气体清单提供方法学依据。

Land use change and forestry （LUCF） is one of the key sectors to report national greenhouse gases （GHG） inventory as required by the United Nations Framework Convention on Climate Change （UNFCCC）. With the aim to further implement the GHG emissions reduction target assigned to all provinces in China, it is an important basic work to estimate the GHG emissions by sources and removal by sinks, and their present situations and distributions at provincial level, that is, to prepare provincial GHG inventory in LUCF sector. The methodology of compiling provincial GHG inventory in LUCF sector is developed to estimate anthropogenic GHG emissions by sources and removal by sinks from LUCF activities at provincial level in China, which mainly includes carbon stock changes in forest and other woody biomass, and GHG emissions caused by forest conversion. The methodology is in compliance with IPCC guidelines on national GHG inventory and incorporated with actual specialty of LUCF activities in China, especially fully considers the availability and reliability of key activity data at provincial level. The methodology also supplies provincial specific defaults of key emission factors. The methodology makes it scientific and operable to compile LUCF GHG inventory at provincial level in China.
