Abstract

Abstract

The article analyzes water and soil erosion, soil desertification, wetland degradation, and human activities in the Yellow River Delta region from 2015 to 2020, based on various satellite remote sensing data and other auxiliary data. The results showed that more than 60% of the area in the Yellow River Delta region has no water and soil erosion, but the phenomenon is more obvious in the farmland areas where the rivers flow through. More than 90% of the region shows mild to moderate soil desertification, and soil desertification was the most severe in 2017. The wetland ecosystem increases, with a total area increase of 91.95 km², accounting for 10.6% of the total area. The total area of human activities decreases by 152.02 hm², with a 66.99% reduction in the agricultural development area and a slight increase in mineral resource development. Overall, ecological environment protection and restoration in the Yellow River Delta from 2015 to 2020 have achieved certain results, and the ecological environment has developed positively, but some ecological problems still exist, and the corresponding ecological governance and protection measures should be taken.
