Abstract:: [Objective] The aims of this study are to reveal the time temporal changes and spatial differentiation in carbon reserves of terrestrial ecosystems on the Loess Plateau caused by land use changes and their mechanisms, and to provide theoretical guidance for maintaining ecological safety and land management on the Loess Plateau. [Methods] GIS(Geographic Information System), statistical models and geographic probes were used to investigate the temporal changes and spatial variation of terrestrial ecosystem carbon storage due to LUCC on the Loess Plateau and the influencing factors of spatial differentiation from 1985 to 2019. [Results](1)From 1985 to 2019, arable land on the Loess Plateau decreased by 2 771 400 hm², while forest land, grassland and construction land increased by 1 679 700 hm², 1 193 500 hm² and 1 284 700 hm², respectively, and other land decreased by 1 437 500 hm².(2)From 1985 to 2019, the carbon stock of terrestrial ecosystems on the Loess Plateau increased by a total of 52.255 1 million tons. After 2002, with the further promotion of ecological projects such as returning forests to grass, the carbon storage increased significantly, especially the carbon storage of vegetation.(3)The hot spot areas for carbon stock changes in terrestrial ecosystems on the Loess Plateau from 1985 to 2002 mainly concentrated in Shaanxi, Shanxi, Ningxia and parts of Inner Mongolia. The cold spot areas mainly concentrated in parts of Henan, Shanxi and Gansu. The hot spot areas from 2002 to 2019 mainly concentrated in Shaanxi, Gansu, Inner Mongolia and some cities in Shanxi. The cold spot areas mainly concentrated in Shaanxi, Henan, Shanxi, Inner Mongolia and some cities in Ningxia.(4)The spatial pattern of carbon storage in terrestrial ecosystems on the Loess Plateau was influenced by a combination of natural and human activities, with annual NDVI, actual evapotranspiration, intensity of human activity, annual precipitation and slope gradient being the main influencing factors, and the interaction between the combination of natural factors and human factors was higher than that between single-type factors. [Conclusion] The increase in forestland and grassland area caused by the ecological project of returning farmland to forestland and grassland has led to an increase in carbon storage in terrestrial ecosystems on the Loess Plateau. With respect to the premise of ensuring food security, the scientific formulation of the differentiated ecological management plans, the promotion of the enhanced ecological engineering in the study area and the restriction of land expansion for construction are conducive to increasing regional carbon storage.
