Problems solved by technology

At present, the measurement of tree diameter at breast height is achieved by manual measurement with the help of a diameter at breasth tape and a vernier caliper. This manual measurement method is not only complicated and inefficient, but also requires manual reading of the measured value, which leads to the The accuracy of the measurement depends largely on the accuracy of the manual measurement operation and the accuracy of the manual reading, which can easily bring a lot of human error to the measurement results of the diameter of the tree, resulting in low efficiency and accuracy of the measurement of the diameter of the tree. Seriously affect the reliability of tree diameter measurement results

Abstract

The invention provides a portable tree diameter at breast height measuring device. The portable tree diameter at breast height measuring device is integrally positioned at a specific height away fromthe ground and a specific distance away from a to-be-measured tree through a main body frame. Therefore, a measurer can remotely and automatically measure the diameter at breast height of a tree to bemeasured by operating the corresponding control mechanism on the handle. Long-distance automatic measurement of the tree can be conveniently realized under the condition that a measurer difficultly touches the tree in the field; and the device is light in weight and small in size, can be conveniently carried to a field environment for measurement anytime and anywhere, and adopts a polyester material with good toughness to perform automatic telescopic surrounding measurement on the tree, so that the automation degree, the efficiency and the accuracy of tree diameter at breast height measurement are improved to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of forestry testing and measurement, in particular to a portable tree diameter measuring device. Background technique [0002] The full name of tree diameter at breast height is tree diameter at chest height, which refers to the diameter of trees that are 1.3 meters above the ground and parallel to the ground. Tree diameter at breast height plays an important role in biomass estimation. By combining tree diameter at breast height and corresponding tree biomass model, the biomass distribution of forest can be estimated quickly and accurately, so as to effectively evaluate the ecosystem cycle of forest system . At present, the measurement of tree diameter at breast height is achieved by manual measurement with the help of a diameter at breasth tape and a vernier caliper. This manual measurement method is not only complicated and inefficient, but also requires manual reading of the measured value, which leads ...
