英文摘要	Monitoring the spatio-temporal dynamic changes in macroalgae aquaculture is crucial to its environmental management.However,few studies have been reported on the comparative monitoring of different macroalgae species.Based on images of the Sentinel-2 satellite and using the normalized difference vegetation index (NDVI) and the support vector machine (SVM),this study monitored the dynamic characteristics of both the Porphyra aquaculture area in the sea area of southern Wendeng District,Weihai City,Shandong Province and the kelp aquaculture area in the sea area of southern Rongcheng City,Weihai City.The results show that:① The Porphyra aquaculture in Wendeng District was first captured in the satellite images of 2016,which is the same as the first year of Porphyra aquaculture in this city;the extraction method used in this study performed well in extracting the information about both the Porphyra and the kelp aquaculture areas overall,with the overall accuracy of 84% and above;② During 2017-2021,the Porphyra aquaculture area monitored through remote sensing increased year by year and showed a trend far away from the shore;③ The Porphyra and kelp aquaculture areas monitored both showed seasonal variations (high in winter and low in summer) of cold-water macroalgae aquaculture,but the minimum and maximum values of the Porphyra aquaculture area appeared 1 ~2 months earlier than those of the kelp aquaculture area.Compared with statistical yearbooks,satellite remote sensing can provide more accurate spatio-temporal information on macroalgae aquaculture.This study can be used as a reference in terms of monitoring technology and data for the management of macroalgae aquaculture in coastal areas of northern China.
