Abstract

This study examines the spatiotemporal dynamics of ecological environment quality (EQ) in the Yellow River Delta (YRD), a vital economic region in Shandong Province, China, that has seen substantial ecological transformations due to accelerated development and population increase. The study utilizes remote sensing and geospatial technologies to develop an Ecological Quality Index (EQI), analyzing its temporal trends and spatial variations over the period from 2000 to 2020. Google Earth Engine (GEE) and Landsat TM/OLI satellite images were used to see at how EQ changed over time. The results shows that EQ has a V-shaped tendency, with the lowest point in 2000 (43.21% extremely low and 19.32% low) and the highest point in 2010 (10.57% very high and 46.72% high). There was a 11.45% growth in places with very high EQ and a 51.61% increase in regions with high EQ by 2020. However, there was a drop from 2010 to 2020, especially in the north and southwest. These findings show how important it is to balance economic growth with protecting the environment. They also give useful information to help safeguard the environment in the YRD.
