| 摘 要： | 国土空间是支撑“双碳”目标实现的核心载体和资源，以城市群为抓手，强化国土空间碳汇冲突管理是跨区域协同推进“双碳”目标顺利实现的重要途径。本文通过分析国土空间碳汇冲突形成机理，构建空间碳汇冲突综合测度指数，以长三角城市群307个县为测度对象，开展实证测度研究并分析其空间格局特征。研究表明：①区域空间碳汇冲突结构整体趋于失衡，稳定可控、基本可控、濒临失控、基本失控和严重失控等级的评价单元数占比分别为15.64%、25.41%、23.45%、26.71%和8.79%；②空间冲突加剧了区域碳汇空间配置失衡，可控等级区域碳汇总量占比达到81.71%，而失控等级区域碳源总量占比达到71.48%；③长三角城市群空间碳汇冲突呈显著空间集聚特征，冷点集中分布于江苏省沿海、皖西大别山区和皖南—浙西—浙南山区，热点主要为上海、南京、苏州、无锡、杭州等城市范围内的县级单元；④处于失控等级的城市集中分布在由环杭州湾向安徽省北部辐射延伸的带状区域内，距离此带状区域两侧越远，冲突指数越低，其中，上海、南京、苏州、无锡4个城市处于严重失控状态，宿州、宿迁、淮安3个城市处于基本失控状态，处于濒临失控状态的城市有15个。最后，提出长三角城市群国土空间碳汇冲突协同管理相关对策建议。

| Abstract: | Territorial space is the core carrier and resource to support the realization of the dual carbon goals. Strengthening the management of territorial carbon sink conflicts at the urban agglomeration scale is an important way to coordinately realize the goals. By analyzing the impact mechanism of spatial conflicts on the carbon sink effect, a comprehensive measurement index was constructed. Taking the 307 counties in the Yangtze River Delta urban agglomeration as the object, this empirical research showed that: (1) The overall structure of territorial carbon sink conflicts has been out of balance, and the number of evaluation units under the consistently controllable, basically controllable, on the verge of out of control, basically out of control, and seriously out of control stage accounted for 15.64%, 25.41%, 23.45%, 26.71%, and 8.79%; (2) The territorial carbon sink conflicts exacerbated the imbalance of regional carbon budgets. The carbon sinks in the controllable-stage regions reached 81.71%, while the carbon sources in the uncontrolled-stage regions reached 71.48%; (3) Territorial spatial carbon sink conflicts have a significant positive correlation and spatial agglomeration. The cold spots are concentrated in the coastal areas of Jiangsu Province, Dabie Mountains in Western Anhui and Southern Anhui-Southwestern Zhejiang Provinces, while the hot spots are mainly counties in Shanghai, Nanjing, Suzhou, Wuxi, and Hangzhou. (4) At the city scale, cities at the out-of-control stage are concentrated in a belt along the Hangzhou Bay to the northern part of Anhui Province. The farther away from the belt, the lower the conflict values. Shanghai, Nanjing, Suzhou, and Wuxi are seriously out of control, Suqian, Suzhou of Anhui Province, and Huai’an are basically out of control, 15 cities are on the verge of out of control. Finally, relevant countermeasures and recommendations are put forward to improve the coordinated management of urban agglomeration territorial carbon sink conflicts. |
