In view of the difficulties existing in the traditional river and lake sand mining management,such as large human investment,disorderly sand mining behavior “can not be seen”and “can not be caught”,difficult law enforcement and low degree of intelligence,and facing the needs of ship management,behavior identification,sand mining volume management and network transmission for the sand mining management in the lakes and rivers,the paper studied on key technologies of sand mining management,such as behavior identification of sand mining vessels,real-time monitoring of sand mining volume,network transmission in complex waters and intelligent control,and developed the river lake sand mining information management platform to realize the intelligent management and control of the sand mining process.The results have been well applied in Poyang Lake area and some reaches of Ganjiang River in Jiangxi province,providing strong technical support for river and lake sand mining management.
