Description

TECHNICAL FIELD

[0001] The utility model relates to the field of ecological environment especially relates to a device for determining the center point of a quadrat in a river or lake riparian zone. BACKGROUND

[0002] Riparian vegetation is a key transitional zone between water and land, with functions such as water conservation, hydrological regulation, and pollutant filtration. Monitoring changes in riparian vegetation can be used to assess the health of the ecosystem, which is beneficial for water and soil conservation, water purification, biodiversity maintenance, and the smooth progress of ecological protection and restoration work, and has high social and economic benefits.

[0003] Traditional methods for monitoring riparian vegetation involve field surveys and quadrat analysis. This method typically involves placing survey quadrats along the slope of the riparian zone one by one. According to the height of the support rod, a horizontal line is drawn, and the slope corresponding to the horizontal line is the center point of the quadrat. This method has a large error and cannot effectively represent the vegetation succession pattern supported by soil capillary water. With the development of remote sensing technology, unmanned aerial vehicle remote sensing technology is currently used to monitor vegetation. A riparian vegetation height model is generated through three-dimensional modeling to achieve the purpose of monitoring vegetation changes. Although this method addresses the time-consuming and labor-intensive shortcomings of traditional methods, it cannot accurately represent the vegetation succession pattern supported by soil capillary water due to limitations in model accuracy.

[0004] Chinese invention patent CN119666841A (publication date: March 21, 2025) discloses an automatic identification and measurement of plant quadrat equipment. This equipment uses a laser projector to project a clear boundary on the plant quadrat, ensuring the accuracy of the monitoring area. The height and angle of the equipment are adjusted by a support frame. Through this equipment, workers can easily achieve non-destructive monitoring of plant quadrats, avoiding damage to the monitored area vegetation caused by traditional methods.
