Abstract: To maintain the leading role in achieving the "double carbon" target in the Yangtze River Economic Belt (YREB), this paper conducted a study on the conflict of national land and spatial carbon sinks of 1 070 counties in the YREB. Land use data in 2020 and relevant socio-economic data such as the carbon emission coefficients of each category were collected. The ArcGIS and landscape ecological risk evaluation model was employed in this study. Measurement of carbon sinks and the spatial patterns under the perspectives of different scales was analyzed. Results showed that: (1) The overall structure of the spatial carbon sink conflict in the YREB was in an imbalance state. The ratios of the evaluation units were quantified as 2.71%, 20.19%, 35.23%, 29.91% and 11.96%, respectively, for stable and controllable, basically controllable, on the verge of being out of control, basically out of control and seriously out of control grades; (2) The territorial spatial carbon sink conflict was characterized by significant spatial agglomeration. The conflict cold spot was centrally distributed in the western direction of the YREB, Aba-Lijiang-Lincang-Xishuangbanna region and Shiyan-Chongqing-Shennongjia-Zhangjiajie region. Conflict hotspot areas were mainly within the cities in the middle reaches of the Yangtze River and coastal areas in the lower reaches; (3) At the city scale, cities in a state of losing control were concentrated and contiguous, mainly within the urban circle of the middle and lower reaches of the Yangtze River, while cities in the middle and upper reaches of the Yangtze River were mostly in a controllable state; (4) At the provincial scale, eastern provinces of the YREB, including Jiangsu, Shanghai, Anhui, and Zhejiang, were in a state of losing control, while western provinces including Sichuan, Guizhou, and Yunnan were in a controllable state. The provinces at the verge of losing control, namely Hubei, Jiangxi, Hunan, and Chongqing, were located in the central part of the YREB, which connected the eastern and western regions and played an important role in spatial regulatory mechanisms.
