Abstract: Based on Landsat TM/OLI images in 2005, 2010, and 2017, we analyzed the distribution and dynamics of tidal creek and vegetation coverage (VC) in the Yellow River Delta costal wetland by remote sensing and geographic information technologies. We conducted correlation analysis between tidal gully and VC in the study area using grid search method. The results showed that vegetation coverage of coastal wetlands in the Yellow River Delta continuously increased from 2005 to 2017. The area of low vegetation coverage decreased by 233.73 km2, while that of high vegetation coverage increased by 165.85 km2. From 2005 to 2017, the length and area of tidal creek in the Yellow River Delta coastal wetland continuously increased, and the frequency also increased. In 2017, the length and area of tidal gully in the southeast of the coastal wetland reached 216.13 km, and the area was 22.23 km2. From 2005 to 2017, the length of tidal creek was negatively correlated with VC, and the tidal creek in 2010 and 2017 was significantly correlated with VC (P<0.05).
