摘要

In China, the Yellow River Delta is a unique region with vulnerable ecosystems, and it is under the largest pressure from various risk sources. In recent years, this region has experienced rapid economic growth. However, the delta is vulnerable to environmental hazards and is seriously affected by various natural and anthropogenic hazards, such as coastal erosion, land subsidence, saltwater intrusion, soil salinization and groundwater pollution, due to natural disasters and human activities, thereby increasing the risk of environmental degradation in the Yellow River Delta.
