Aiming at problem of insufficiency of forest resources protection and backward infrastructure construction of the area far away from urban

and the traditional wireless sensor networks（ WSNs） uses fixed sink node to receive data

and communicates with multi-hop transmission

which is easy to produce"energy holes"

forest prevention and monitoring system of ground-air interaction multi-sensory fusion is designed. The system uses air mobile sink node and ground cluster head node to work together. The air mobile sink node is formed by using UAV embedded sink node

eliminate the limitation of moving track of ground moving equipment due to the high density of ground obstacles. And the air mobile sink node and the ground communication node achieve single-hop transmission of data

not only improve the efficiency and reliability of data transmission

but also solve the problem of uneven energy consumption of each node. The system application shows that the proposed system provides a good solution for protection and monitoring of forest resources in large areas.
