【摘要】：中国已经成为全球碳排放总量最大的国家,且由于正处在快速工业化和城市化的关键时期,与之伴随的继续增加的碳排放越来越受到国际关注,对碳减排的压力亦日益增加。碳减排需要从减少碳源和增加碳汇两个方面同时推进。本文利用中国森林资源清查数据和相关统计数据,结合排放系数法、森林碳汇蓄积量法和草地固碳速率法,比较全面的估算了省级尺度区域的能源消耗碳排放、森林碳汇、草地碳汇和耕地碳汇,分析了中国碳排放总量、人均碳排放、地均碳排放、能源强度的区域差异,以及碳汇和碳盈余的空间格局特征:①从省级区域单元看,碳排放总量列前三名的是山东、山西和河北,较低的省区为宁夏、青海和海南;人均碳排放较高的为内蒙古、山西和宁夏,较低的省区为江西、海南和广西;地均碳排放最高的为上海,最低的省区为青海;碳排放强度最低的省区包括北京、广东、上海、浙江等。②从全国来看,森林碳汇占总碳汇的52.85%,云南和黑龙江森林碳汇优势显著;草地碳汇占总碳汇的38.51%,主要集中在内蒙古、青海和新疆等省区;耕地碳汇占总碳汇的8.63%,主要集中在黑龙江、吉林、河南和辽宁等省区。今后,东部地区应当转变发展方式,通过科技创新,提高能源利用效率;中部地区要抓住绿色发展机遇,推动低碳产业跨越发展;东北地区的黑龙江碳汇能力较强,可积极参与国际碳交易;西部地区应加强管理,加速技术改进,提高能源利用效率,并加强生态环境建设,增强碳汇能力。
[Abstract]:China has become the country with the largest global carbon emission, and as a result of being in the critical period of rapid industrialization and urbanization, the continued increase of carbon emissions associated with it has attracted international attention, and the pressure on carbon emission reduction has also increased. Carbon reduction needs to be promoted simultaneously from both the reduction of carbon sources and the addition of carbon sinks. In this paper, the energy consumption carbon emission, the carbon sink of the forest, the carbon sink of the grassland and the carbon sink of the cultivated land are comprehensively estimated by using the forest resources inventory data and related statistical data of China, combined with the emission coefficient method, the forest carbon sink accumulation amount method and the grass solid carbon rate method. The spatial pattern of carbon emission, carbon emission per capita, carbon emission and energy intensity in China, and the spatial pattern of carbon sink and carbon surplus were analyzed. The top three of the total carbon emission were Shandong, Shanxi and Hebei, and the lower provinces were Ningxia. In Qinghai and Hainan, the higher per capita carbon emission is Inner Mongolia, Shanxi and Ningxia, and the lower provinces are Jiangxi, Hainan and Guangxi; the highest carbon emission in the land is Shanghai, the lowest provinces are Qinghai; the provinces with the lowest carbon emission intensity include Beijing, Guangdong, Shanghai, Zhejiang and so on. From the national point of view, the forest carbon sink accounts for 52.85% of the total carbon sink, and the carbon sink of the forest in Yunnan and Heilongjiang is significant; the carbon sink of the grassland accounts for 38.51% of the total carbon sink, mainly in the provinces of Inner Mongolia, Qinghai and Xinjiang; the carbon sink of the cultivated land accounts for 8.63% of the total carbon sink, which is mainly concentrated in the Heilongjiang and Jilin provinces. Henan and Liaoning provinces and other provinces. In the future, the eastern region should change the way of development, improve the energy utilization efficiency through scientific and technological innovation, seize the green development opportunity in the central region, and promote the development of the low-carbon industry; the Heilongjiang carbon-sink capacity in the Northeast is strong, and can actively participate in the international carbon trade; The western region should strengthen the management, accelerate the technological improvement, improve the energy utilization efficiency, and strengthen the construction of the ecological environment and enhance the carbon sink capacity.
