The dynamic stability of the local ecological environment is related to changes in land use patterns and ecological sensitivity. The study aims to identify the land use characteristics and dynamic change features in Guangzhou City using RS and GIS technology. We choose six ecological sensitivity factors, such as land use type, elevation, watershed buffer, vegetation cover, slope, and slope direction, and use the analytical hierarchy process (AHP) to obtain the results of single-factor and comprehensive ecological sensitivity. The findings indicate that, in terms of land use, the area of four types—forest land, grassland, arable land, and unused land—decreased from 2000 to 2020, while the area of water bodies and construction land rose, with a minimal overall change. According to total ecological sensitivity, very sensitive areas make up the majority of the total area and are primarily found along the northern township boundary; very low-sensitive and mildly sensitive areas are mostly found in the south and center. In order to encourage the development of an ecological civilization in the city, Guangzhou City must establish the idea of harmony between people and the land and increase the ecological conservation function.
