Mangroves are distributed in the tropical and subtropical coastal intertidal zones, playing a critical role in the global carbon cycle and providing service value for ecological and ecological economic development. But with the development of human activities and the deterioration of the natural environment, mangrove resources have sharply decreased. The article uses Landsat images of 2000, 2005, and 2010, and Sentinel-2 images of 2015 and 2020. Through decision tree classification and object-oriented classification methods, combined with field surveys, the spatial distribution and area of mangroves each year are extracted, and the spatial distribution dataset of mangroves in Qiao Island from 2000 to 2020 is produced. The article dataset can analyze the spatial dynamic evolution of mangroves, providing important references for scientific research such as the dynamic changes of mangroves on Qiao Island and the evaluation of ecological environment quality; providing decision-making support for the protection, restoration, and management of mangrove wetlands; and providing basic data support for environmental monitoring in Zhuhai City and Guangdong Province.
