【摘要】：土地利用变化及林业(LUCF)活动是生态固碳最重要手段。研究确定LUCF温室气体排放核算制度和方法,对平衡碳排放、开展全国统一碳市场交易具有重要基础作用。在综述LUCF温室气体核算理论和方法基础上,借鉴IPCC指南和《省级温室气体清单编制指南(试行)》推荐的基本方法,构建了符合地域特色的LUCF温室气体排放核算制度和方法。采用2014年第九次国家森林资源清查数据,以全国低碳试点省陕西省为实证对象,初步核算了陕西省LUCF温室气体的净排放量,并从排放能力、排放结构和空间特征等角度揭示了陕西省LUCF温室气体的排放特征。结果显示:(1)2014年,陕西省LUCF温室气体净吸收量为1 698.42万t CO_2e,其中森林及其他木质生物质碳贮量净吸收1 852.67万t CO2e,森林转化净排放154.25万t CO_2e。(2)乔木林等优势树种,是陕西省LUCF温室气体排放中重要的固碳源(吸收源)。(3)陕南地区是重要固碳贡献区,陕北地区森林固碳能力较差。最后,针对LUCF温室气体排放核算制度和方法不够完善、森林固碳能力差异较大、区域固碳分化严重等问题,提出了健全温室气体核算制度、平衡森林资源空间分布、改善固碳树种结构等加强陕西省LUCF活动应对气候变化统计核算制度和能力建设的基本措施。
[Abstract]:Land use change and forestry (LUCFC) activities are the most important means of ecological carbon sequestration.The determination of LUCF greenhouse gas emission accounting system and method plays an important role in balancing carbon emissions and developing national unified carbon market trading.On the basis of summarizing the theory and method of LUCF greenhouse gas accounting and referring to the basic methods recommended by IPCC guidelines and provincial greenhouse gas inventory compilation guidelines, a regional LUCF greenhouse gas emission accounting system and method is constructed.Using the data of the Ninth National Forest Resources inventory in 2014 and taking Shaanxi Province as an empirical example, the net greenhouse gas emissions of LUCF in Shaanxi Province were preliminarily calculated, and the emission capacity was analyzed.The emission structure and spatial characteristics of LUCF greenhouse gas in Shaanxi Province were revealed.The results showed that in 2014, the net greenhouse gas uptake of LUCF in Shaanxi Province was 1 6.9842 million t CO2e. among them, forest and other woody biomass carbon storage absorbed 1 8.5267 million t CO2e. forest conversion resulted in net emission of 1.5425 million t CO2e.2) Arbor forest, and so on.It is an important carbon sequestration source (absorption source) in LUCF greenhouse gas emission in Shaanxi Province. Southern Shaanxi is an important carbon sequestration contribution area, and forest carbon sequestration capacity is poor in northern Shaanxi.Finally, aiming at the problems such as LUCF greenhouse gas emission accounting system and method is not perfect, forest carbon sequestration ability difference is big, regional carbon sequestration differentiation is serious and so on, the paper puts forward a perfect greenhouse gas accounting system to balance the spatial distribution of forest resources.To improve the structure of carbon sequestration tree species and to strengthen the basic measures of climate change statistical accounting system and capacity building for LUCF activities in Shaanxi Province.
