Description

Technical Field

[0001] The present application relates to the technical field of survey plot setting, and more specifically, to a portable plant plot survey setting device. Background Art

[0002] Vegetation plot survey is a common method used to study and evaluate the characteristics of plant communities. It is a data collection method for the species composition, community structure, biomass and environmental factors of plant communities in different regions with plots of different sizes (usually 1m×1m for herbaceous plots, 5m×5m for shrub plots, and 20m×30m for tree plots) as survey units. Vegetation plot survey data is an important part of plant science data. It is the basic data for conducting research on vegetation ecology, geography, botany, etc. It plays a key role in revealing the species composition and distribution pattern, structure and function of vegetation. Vegetation plot survey data is the basic data reflecting the background status of natural resources in the region and even the country. However, the current plot survey installation device is mainly based on the assumption of flat land. In special habitats such as water areas, swamps and other wetlands, the plot installation may be restricted due to the disturbance of external factors such as water flow and waves, making it difficult to accurately obtain representative samples.

[0003] The document with prior art publication number CN 220708758 U provides a portable plant sample plot investigation and setting device. The device can investigate the structure composition and biomass of aquatic plant communities in special wetland habitats such as water areas or swamps through the optimized matching design of telescopic rods, air floating plates, connecting ropes and connecting heads, and make more accurate and objective evaluations.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when the device is in use, it needs to be coordinated with an air pump, and the air pump needs to be coordinated with a power supply when in use. Therefore, it is easily limited by the power supply when in use. At the same time, the structure uses a hydraulic rod, which makes the overall structure relatively bulky, and increases the weight of the carrier when used in swamps and waters.

[0005] In view of this, we propose a portable plant sample plot survey setting device. Utility Model Content
