Abstract

In order to study the ecological environment changes of Baiyangdian wetland, a total of six Landsat remote sensing images from 2003,2007,2011,2015,2019 and 2023 were selected, and the Principal Component Analysis method(PCA) was used to integrate four ecological indicators: greenness (NDVI),humidity (WET),dryness (NDBSI) and heat (LST) to construct a remote sensing ecological index model (RSEI),and to study and analyze the changes of ecological environment quality of Baiyangdian wetland from 2003 to 2023.The study revealed that the environment of Baiyangdian wetland is primarily influenced by vegetation coverage, with overall ecological quality demonstrating a fluctuating upward trend during this period. These findings can reflect the changes of ecological environment quality of Baiyangdian wetland to a certain extent and can provide a theoretical reference and scientific basis for the management and protection of wetland ecological environment.
