Before 2000, a large number of mangrove forests in Guangxi were cut down for aqua-cultural purposes. After 2000, with the introduction of national, provincial and municipal policies on mangrove protection, this phenomenon was less frequently seen. By using the object-oriented method, referring to the spectral and texture characteristics of the ground target, and using the Landsat remote sensing images of 2000-2019, this paper extracts and analyzes the area and change of mangrove and aquaculture area in Maowei sea, Guangxi. The results show that the use of object-oriented methods can extract mangroves and aquaculture areas with higher accuracy. The area of mangroves generally shows an upward trend, with the area of aquaculture increasing first and then decreasing.
