In recent years, Jinta county has adopted the philosophy that "clear waters and green mountains are invaluable treasures." Guided by this vision, the county has prioritized the implementation of an integrated sand control approach that combines biological measures with engineering solutions. 

Leveraging advanced technologies, Jinta has promoted cost-effective and highly efficient sand stabilization techniques, including rice straw checkerboard grids, drone-based transportation, and mechanical sand compaction. These efforts have significantly enhanced the efficiency of sand control initiatives, further fortifying the ecological security barrier in western China.
