It is the basic work of forest resource management and supervision. Establishing long-term fixed monitoring sample plots can realize periodic, quantitative and standardized monitoring of forest resources, timely grasp the current situation and dynamic changes of forest resources, and predict the development trend of forest resources, providing basic data support for forestry scientific research and technology research and development, and providing decision basis for forestry management science.

[0003] The forest fixed monitoring sample plot is generally rectangular, and the four corners of the rectangle need to be marked with obvious markers in the selected monitoring area. The commonly used markers are cement piles, PVC or glass steel piles. These commonly used piles have some problems: (1) large volume or heavy, inconvenient to carry; (2) once the pile is made, the specification (length, width, height) is fixed, and it is not flexible to use; (3) it is very inconvenient to bury the pile. At present, one of the commonly used methods is to dig a hole or make a hole first, and then bury it. However, the soil layer in the forest is not necessarily very deep, and there are stones and other phenomena in the soil, so the hole cannot be dug very deep. This method is labor-intensive and not easy to bury solidly, and the pile is easy to shake and fall. Another method is to dig a hole and bury it, and then use cement to fix it. This method is also labor-intensive and high in cost, and it is not convenient to construct in the forest area.
