The article uses Landsat TM and OLI multispectral images from 2006,2013,and 2020 as data sources to extract the surface flooding range of the Momoge National Nature Reserve,calculate the values of hydrological connectivity index values,and analyze the trend of hydrological connectivity changes in the protected area during the research period.During the whole research period,the surface flooding area of the protected area showed a trend of first increasing and then decreasing,and the connectivity between water patches gradually strengthened,and the connected patches gradually approached a whole.
