Based on Landsat MSS /TM/OLI remote sensing images, the land cover datasets of Xianghai in five periods from 1977 to 2018 were obtained by artificial visual interpretation and classifications. By analyzing wetland dynamics, landscape indices, wetland centroid migration, the influence of human activities on Xianghai wetland landscape change was quantitatively analyzed. The results show that the wetland area in the study area has decreased slightly over the past 40 years, the wetland core has shifted southward, and the anthropogenic disturbance has decreased in the past 10 years.
