Analysis of key elements and measures for the management of river sand mining in China
As a crucial component of the sand and gravel resource system,the supply-demand dynamics,management models,and utilization of river sand directly impact market supply while also affecting flood control safety and the ecological stability of rivers and lakes.With the continued decline in sediment inflow across major river basins,significant shifts in the supply-demand structure of sand and gravel resources,and the deepening implementation of the river and lake chief system nationwide,river sand mining management is facing new challenges and higher requirements.From a macro perspective,this study systematically analyzes the current supply and demand status of river sand resources.Key management elements are explored,including the legal framework,ownership of river sand resources,sand mining permits,transfer of river sand mining rights,utilization of dredged sand,and on-site management systems.Targeted measures are proposed,such as improving legislation,clarifying management responsibilities,optimizing licensing mechanisms,standardizing the use of dredged sand,defining revenue allocation,and strengthening on-site management.To enhance river sand mining management under evolving conditions,it is recommended to accelerate legislative processes,advance research and application of management technologies,and optimize existing management models.The study aim to promote the effective protection of river and lake ecosystems and ensure the sustainable utilization of sand resources,providing a scientific foundation for policymaking and management practices.
