中文摘要
      为解决超大城市发展与生态修复、碳汇能力保障之间的矛盾,基于可持续发展框架,以“碳汇特征明晰-碳增汇适宜性评价-碳增汇区域综合划分”的研究思路,在利用改进的CASA模型和土壤微生物呼吸方程定量估算北京市2001~2020年植被净生态系统生产力(NEP)的基础上,采取趋势分析、波动性分析、Hurst指数法分析和地理探测器等方法,探明北京市碳汇演变特征、空间分异驱动因子并综合确定碳增汇分区. 结果表明:① 在时间尺度上,2001~2020年北京市NEP的总体变化趋势为波动上升;在空间尺度上,西北部的NEP大于东南部,整体呈现由中心发散性扩大趋势;79.6%的区域NEP呈增加趋势,但具有可持续性增长或由减少反转的区域范围仍较小;碳汇区域中波动性最小的为怀柔区、延庆区和房山区. ② 北京市NEP空间分异主要驱动因子解释度从大到小为植被覆盖度、土地利用类型、海拔、人类干扰程度、坡度、经济活动水平、人口密度、GDP和年平均气温;驱动因子交互作用为双因子增强或非线性增强,NEP空间分异特征受多个驱动因子共同作用. ③ 结合可持续碳增汇适宜性评价和碳汇演变特征将北京市划分为碳增汇核心区、碳增汇重点区、碳增汇优先区、碳增汇潜力区和碳增汇补充区这5类,分别占市域面积的47.5%、17.7%、15.4%、11.4%和8.0%. 研究结果可为北京市碳增汇区域划分及制定管理措施提供依据. 超大城市实现可持续发展和碳中和目标,可综合多类驱动因子和碳汇演变特征的共同作用确定碳增汇分区,以针对性采取碳增汇策略.
英文摘要
      To address the contradiction between the development of megacities and ecological restoration, as well as the carbon sequestration capacity guarantee, this study was based on the sustainable development framework and adopted the research approach of “clarifying carbon sequestration characteristics, evaluating carbon sequestration suitability, and comprehensively dividing carbon sequestration areas” to propose carbon sequestration zoning and management measures for Beijing under the sustainable development framework. First, we used the improved Carnegie Ames Stanford Approach (CASA) model and soil microbial respiration equation to quantitatively estimate the net ecosystem productivity (NEP) of vegetation in Beijing from 2001 to 2020. The spatiotemporal distribution pattern and evolution characteristics were analyzed and trend, volatility, and continuity were used as evaluation indicators for carbon sequestration characteristics. Second, from a sustainable perspective, considering the natural, social, and economic conditions of Beijing, the driving factors of NEP in Beijing were analyzed from the perspectives of single-factor detection and interactive detection using geographic detector methods. Finally, the driving factors were used as suitability evaluation indicators for sustainable carbon sequestration. Risk detection was used to assign values to different intervals of the driving factors based on their corresponding NEP mean values. Combined with the NEP carbon sequestration characteristics in Beijing, the sustainable carbon sequestration zones in Beijing were determined. The results showed that: ① On the time scale, the overall trend of NEP change in Beijing from 2001 to 2020 was fluctuating upward, and on the spatial scale, NEP in the northwest was larger than that in the southeast. The overall trend showed a divergent expansion from the center of Beijing, and 79.6% of the regional NEP showed an increasing trend; however, the scope of the region with a sustainable growth or a reversal from a decrease was still relatively small. The region with the least volatility among the carbon sequestration regions included Huairou, Yanqing, and Fangshan Districts. ② The major drivers of spatial variability of NEP in Beijing were, in descending order of explanatory degree, vegetation cover, land use type, elevation, degree of human interference, slope, level of economic activity, population density, GDP, and average temperature. The interaction of the drivers was a two-way enhancement or non-linear enhancement and the characteristics of spatial variability of NEP were affected by the joint action of multiple drivers. ③ Combined with the evaluation of the suitability of sustainable carbon sequestration and the characteristics of the evolution of carbon sequestration, Beijing was divided into five categories: carbon sequestration core areas, carbon sequestration key areas, carbon sequestration priority areas, carbon sequestration potential areas, and carbon sequestration supplemental areas, which accounted for 47.5%, 17.7%, 15.4%, 11.4%, and 8.0% of the municipal area, respectively. The results of this study can provide a basis for the delineation of carbon sequestration areas and the formulation of management measures in Beijing. To realize sustainable development and carbon neutrality, megacities should define carbon sequestration zones by combining the effects of multiple drivers and the evolutionary characteristics of carbon sequestration, to adopt targeted carbon sequestration strategies.
