| Summary: | The exploitation of sea sand resources is a kind of mineral resources development activity that changes the natural attributes of sea areas. The prominent problems caused by sea sand mining mainly include changes in seabed topography and erosion environment, coastal erosion, which have a significant negative impact on marine resource ecology. Based on the key bottleneck issues in the rational development and utilization of sea sand resources in the South China Sea, including legal and policy gaps, the need to improve coordination mechanisms, inconsistent evaluation standards, lack of planning plans, and inconsistent definition of value assessment connotations, this study proposes practical countermeasures and suggestions to strengthen the rational development and utilization of sea sand resources, such as improving policy and institutional systems, clarifying resource inventories, reconstructing coordination mechanisms, scientifically formulating planning plans, and conducting post-assessments.
