英文摘要	Aquaculture is one of the important ways for human beings to obtain food, and aquaculture ponds are one of the main production modes of aquaculture. Based on the Landsat data of 30 m spatial resolution, the normalized water index (NDWI) was used to set the threshold, and the linear mixed pixel decomposition model was used to decompose the mixed pixel, and the water abundance was obtained. The water abundance and NDWI were statistically analyzed. The aquaculture ponds with water abundance of 0. 7 and a bove and the corresponding NDWI threshold were extracted. The distribution map of aquaculture ponds in typical areas on the west coast of the Pearl River Estuary from 1990 to 2021 was obtained. The results show that the aquaculture ponds in typical areas on the west coast of the Pearl River Estuary experienced a rapid increase in aquaculture area from 1990 to 2010, and a slight decrease in aq uaculture area from 2010 to 2021. The research results can provide certain reference for the analysis of the development law of aquacul ture ponds and the rational planning of aquaculture ponds
