[0002] It is of great significance to understand and protect plant resources and protect ecological environment to study the characteristics of plant community, species diversity and its distribution pattern. The investigation of species diversity and its distribution pattern of plant community in large-scale range is carried out by using sampling method. The sampling method is usually to arrange multiple 1m×1m quadrats in the sample plot, and to count the dominant species, plant species, number of plants, coverage and biomass in the quadrat.

[0003] At present, there are mainly four kinds of herb plant community quadrat investigation devices in actual use: 1. A simple device composed of a steel drill, a tape measure and a hook. The device has simple structure, but the tape measure itself has certain elasticity, and a single steel drill is inserted into the soil, so the fixing effect is poor, and the device is easy to deform, resulting in large measurement error. 2. A fixed quadrat frame welded from iron wire. The device has simple structure, but is not easy to fix and disassemble, leading to inconvenience in carrying, easy deformation and large error. 3. A foldable quadrat frame. The quadrat frame cannot be fixed, has no scale for measurement, is not easy to measure, has many connecting parts, is easy to lose in the field and prone to failure. 4. A photographic quadrat. The device is composed of a support, a camera and a data line, and is complicated to assemble, the camera is not easy to balance, the device is many and heavy, and is inconvenient to carry in the field.
