ABSTRACT

Carbon emission is an important cause of current climate warming. Land use (LU) change affects regional carbon emission and carbon absorption, which in turn affects regional carbon budget. This study examines the impact of LU change on carbon budget in the Greater Bay Area (GDHKMGBA) from 1980 to 2020. By calculating the dynamic attitude of LU, various types of land change were analyzed, carbon budget was calculated by carbon emission coefficient method, and temporal and spatial evolution characteristics were analyzed by Moran index, nuclear density analysis, center of gravity and standard deviation ellipse. The results show that: (1) In the past 40 years, the construction land(CL) and water area increased, the cultivated land and forest land decreased, and the land change was significant; (2) The carbon budget showed an increasing trend, mainly due to the increase of CL and the decrease of forest land; (3) The spatial auto-correlation of carbon budget was significant, and the shift trend of the center of gravity was consistent with the center of gravity of carbon emission(GOCE), showing a "northwest - southeast" distribution.
