Abstract

Land use changes considerably influence carbon emissions and carbon storage, rendering an investigation into the spatial and temporal patterns of carbon emissions from land use transformations is essential. Such a study holds great importance to the rational allocation of land resources, the improvement of land use efficiency, and the realization of energy saving and emission reduction. Herein, based on land use and energy data from 1990—2020 in 22 county units in Ningxia Province, China, we comprehensively applied the carbon emission risk index and carbon footprint pressure index to analyze land use changes, spatial differentiation of carbon emissions, and carbon emission risk associated with land use of counties in Ningxia. The results are as follows: (1) Land use change in Ningxia has been substantially strong from 1990 to 2020. Notably, the dynamic degree of construction land was the largest, with an increase of 1578.48 km2. (2) During this period, the net carbon emissions of land use in Ningxia increased by 4969.25×104 t. Notably, net carbon emissions exhibited an average annual growth rate of 15.71% from 2000 to 2020, nearly doubling every decade. Meanwhile, the carbon emissions of construction land account for >86% of the total carbon emissions. The amount of carbon absorptions in Ningxia increased by 23.76×104 t, mainly forest carbon absorptions, accounting for >75% of the total carbon absorptions, showing a pattern of local agglomeration and overall dispersion. (3) The land use carbon emissions of each county showed an increasing trend but with a profound difference. Northern counties experienced the most pronounced growth rate of carbon emissions, and the spatial distribution pattern of carbon emissions of the counties along the Yellow River was higher than that in the central and southern counties. (4) Each country suffers from high risk and pressure of land use carbon emissions, where carbon emissions and carbon absorption are highly uncoordinated, leading to an imbalance in the ecosystem carbon balance.
