摘要/Abstract

摘要： “双碳”目标是我国解决资源环境约束突出问题和实现人与自然和谐共生的重大战略决策,植被固碳提升则是实现“双碳”目标的重要路径,定量模拟区域植被固碳潜力是国土空间格局优化的前提,有助于保障“双碳”目标的顺利实现。基于此,本研究采用相似生境法模拟自然条件下黄土高原的植被固碳潜力,并按照潜力分级-需求分类-管理分区的思路划分黄土高原固碳管理分区,提出对策建议。结果表明: 2000—2020年,黄土高原植被年固碳总量由214.32百万t上升至354.92百万t,增长了65.6%;整体分布从西北到东南呈阶梯状增加,高值区集中在秦岭山系、吕梁山系、子午岭和中条山等山地,低值区主要包括城镇化程度较高的城区及周边区域。自然条件下黄土高原植被固碳潜力均值为832.71 g·m^-2,比2020年现状高52.3%,尚可增加的固碳量为185.76百万t。结合剩余固碳潜力与“三生空间”分布格局,将黄土高原划分为重要碳汇提升区、生态碳汇恢复区、生活绿地建设区、生态碳汇保育区、农业碳汇提升区、城镇碳汇巩固区、绿色农业发展区、经济发展控碳区9类,并针对不同分区提出差异化固碳增汇管理策略。研究结果可为“双碳”目标下的区域低碳发展和景观管理提供有效政策支持。

Abstract: The “dual carbon” goal of China is a major strategic decision for solving critical resource and environmental constraints and fulfilling the inherent requirement for harmonious coexistence between human society and nature. Enhancing vegetation carbon sequestration is a crucial pathway to achieving the “dual carbon” goal. Quantitative simulation of regional vegetation carbon sequestration potential is vital for optimizing land use patterns and securing the smooth achievement of the “dual carbon” goal. In this context, we used a similar habitat method to simu-late vegetation carbon sequestration potential under natural conditions on Loess Plateau. Through potential classification-demand categorization-management zoning, we delineated carbon sequestration management zones for Loess Plateau and proposed specific strategies. The results showed that total vegetation carbon sequestration of Loess Plateau increased from 214.32 million t to 354.92 million t from 2000 to 2020, representing a growth of 65.6%. Spatially, a gradual increase was found from northwest to southeast, with high-value areas distributed in mountainous regions, such as the Qinling Mountains, Lyuliang Mountains, Ziwuling, and Zhongtiao Mountains. Urban areas with relatively advanced urbanization and their surrounding zones were characterized by low values. Under natural conditions, the average vegetation carbon sequestration potential on Loess Plateau was 832.71 g·m^-2, representing an increase of 52.3% compared to the 2020 baseline, resulting in an additional carbon sequestration of 185.76 million t. Based on the remaining carbon sequestration potential and the distribution pattern of the production-living-ecology space, the Loess Plateau could be classified into nine categories, including important carbon sink enhancement area, ecological carbon sink restoration area, urban green space development area, ecological carbon sink conservation area, agricultural carbon sink enhancement area, urban carbon sink consolidation area, ecological carbon sink control area, green agricultural development area, and economic development carbon control area. Carbon sequestration enhancement and management strategies specifically tailored to each zone were proposed. The findings would provide valuable support for regional low-carbon development and landscape management under the “dual carbon” goal.

Key words: carbon sequestration and sink enhancement potential, management zoning, optimization strategy, Loess Plateau
