摘要:

准确估算生态系统碳源/汇量,探究其时空演变规律对于河北省国土空间优化管理及低碳转型具有重要意义。基于能源消耗数据、遥感数据、碳密度数据、水体碳通量数据、盐沼和滨海养殖数据,分别计算了河北省能源消耗碳排放情况、陆地生态系统碳汇和水体碳通量情况,并对河北省碳中和度进行了分析。结果表明:①河北省2000—2019年能源碳排放整体呈现不断增长的趋势,2019年碳排放量约为2000年的4倍,年均增长率约为6.98%。②河北省2000—2020年间生态系统净生产力(NEP)总量变化趋势波动大,但整体呈现上升的趋势;内陆水体碳通量年际变化不大,呈现略微上升的趋势;海水养殖蓝碳总体呈现出增长趋势,从2000年的0.66万t上升至2020年的3.56万t。③汇总河北省国土空间碳源/汇的核算结果,分析可知,2020年生态系统碳汇总量约能抵消3.54%能源碳排放。由此看来,河北省目前碳中和能力较低,低于全国平均水平(15%),减碳增汇压力巨大。

Abstract:

[Objective] Accurately estimating the carbon sources and sinks of ecosystems and exploring their spatiotemporal evolution patterns are of great significance for optimizing territorial space management and promoting the low-carbon transition in Hebei Province. [Methods] This study utilized energy consumption data, remote sensing data, carbon density data, water carbon flux data, and salt marsh and coastal aquaculture data to calculate the carbon emissions from energy consumption, terrestrial ecosystem carbon sinks, and water carbon fluxes in Hebei Province. Additionally, a scientific analysis of the degree of carbon neutrality was conducted. [Results] (1) The overall carbon emissions from energy consumption in Hebei Province showed a continuous upward trend from 2000 to 2019, with emissions in 2019 reaching approximately four times those of 2000, at an average annual growth rate of about 6.98%. (2) The total NEP (Net Ecosystem Production) in Hebei Province from 2000 to 2020 showed significant fluctuations but an overall upward trend. The interannual variations in carbon fluxes from inland waters were minimal, showing a slight increasing trend. Blue carbon from marine aquaculture demonstrated overall growth, increasing from 6 600 tons in 2000 to 35 600 tons in 2020. (3) A comprehensive analysis of the carbon sources and sinks in Hebei Province’s territorial space revealed that the total ecosystem carbon sinks in 2020 could offset approximately 3.54% of the carbon emissions from energy consumption. [Conclusion] This suggests that Hebei Province currently has a relatively low carbon neutrality capacity, below the national average (15%), and faces enormous pressure to reduce carbon emissions and increase carbon sinks.
