Spatio-temporal Evolution Patterns of Carbon Budget in the Xinjiang Production and Construction Corps

• • Terrestrial carbon absorption declined continuously from 2010 to 2020, with net absorption decreasing by [specific % not provided] annually, indicating a persistent drop in carbon sequestration capacity; this trend underscores the urgency of protecting existing sinks. • • Anthropogenic carbon emissions rose steadily, but growth rate sharply declined after 2015; energy consumption accounted for >95% of emissions per division and 99% regionally, highlighting the dominant role of fossil fuel combustion. • • By 2020, the 8th, 13th, and 6th Divisions, covering 26.52% of the land area, contributed 78.16% of net carbon emissions, demonstrating extreme spatial concentration and the need for targeted mitigation policies. • • Carbon balance zoning classified the region into 1 carbon sink functional zone, 9 low-carbon maintenance zones, and 3 high-carbon optimization zones, with high-carbon zones forming a strip in the central-east covering 26.52% of the area, guiding differentiated low-carbon strategies.
