摘要:
土地利用变化是区域碳排放变化的主要驱动力,研究土地利用变化对碳排放的影响有助于制定碳排放政策。基于土地利用现状数据和能源消耗数据,构建碳排放评价模型,测算河北省2000-2020年土地利用碳排放量,利用标准差椭圆模型探究研究区碳排放空间格局分布特征,依据碳排放经济贡献系数和碳生态承载系数提出碳平衡分区方案及优化对策。结果表明,①2000-2020年河北省碳排放总量整体上呈现明显的上涨趋势,从9.01×107 t上升到2.75×108 t,2000-2010年碳排放量增长速率快速提升,2010-2020年碳排放量增长相对缓慢。②河北省碳排放强度呈现多圈层结构空间分布特征,主要以资源型城市为中心向外呈圈层结构扩散,石家庄和沧州核心市区次圈层结构逐渐显现。③河北省县域碳排放经济贡献系数空间特征呈四周低中间高,碳生态承载系数呈现西北高东南低的空间分布规律。④基于碳平衡分析将河北省划分为碳汇功能区、低碳保持区、经济发展区、碳汇发展区和高碳优化区,并提出了相应的发展策略。
Abstract:
Land use change is the main driving force of regional carbon emissions change. Studying the impact of land use change on carbon emissions will help to formulate carbon emission policies. Based on the current land use data and energy consumption data, a carbon emission evaluation model was built to calculate the land use carbon emissions of Hebei province from 2000 to 2020. The standard deviation ellipse model was used to explore the spatial pattern distribution characteristics of carbon emissions in the study area. Based on the economic contribution coefficient of carbon emissions and the carbon ecological carrying coefficient, the carbon balanced zoning scheme and optimization countermeasures were proposed. The results showed that, from 2000 to 2020, the total carbon emissions of Hebei province showed an obvious upward trend, rised from 9.01×107 t to 2.75×108 t, the growth rate of carbon emissions from 2000 to 2010 improved rapidly, and the growth of carbon emissions from 2010 to 2020 was relatively slow. The carbon emission intensity of Hebei province presented a spatial distribution characteristic with multi-circle structure, mainly centered around the resource-based cities and spreaded outward in a circle structure, and the sub circle structure of Shijiazhuang and Cangzhou core urban areas gradually became apparent. The spatial characteristics of the economic contribution coefficient of carbon emissions of counties in Hebei province were low in four directions and were high in the middle, and the carbon ecological carrying coefficient was high in the northwest and was low in the southeast. Based on the carbon balance analysis, Hebei province was divided into carbon sink functional area, low carbon conservation area, economic development area, carbon sink development area and high carbon optimization area, and corresponding development strategies were proposed.
