Description

TECHNICAL FIELD

[0001] The utility model belongs to forestry carbon sink measurement monitoring technical field, concretely relates to a tree carbon storage measurement device. BACKGROUND

[0002] Tree carbon storage measurement is an important technical means for evaluating the carbon sequestration capacity of forest ecosystems, and its measurement data has important value for climate change research, carbon sink trading and ecological protection. The commonly used measurement device currently usually adopts a handheld design, accurately obtains the diameter at breast height, tree height and volume of the tree by integrating a spectral analysis module or a laser scanning unit and other detection components, and indirectly calculates the tree biomass and carbon storage by combining the biomass conversion factor method. In actual operation, the user needs to tightly or accurately align the detection head at the front end of the device with the specific part (such as the diameter at breast height) of the measured tree, and complete data acquisition while keeping the device stable.

[0003] However, the prior art has obvious limitations: in a forest environment with large slope and steep terrain, the user needs to hold the device with one hand or both hands for measurement operation, which not only makes it difficult to maintain stable contact between the device and the measured tree, but also causes problems such as device shaking and positioning deviation due to complex terrain, directly affecting the measurement accuracy. In addition, long-time handheld operation can cause personnel fatigue, and there are safety hazards in dangerous terrain. For large-area continuous measurement application scenarios, the operation efficiency of the traditional device is significantly reduced, which cannot meet the demand of modern forestry monitoring for efficient and convenient measurement. Therefore, we propose a tree carbon storage measurement device to solve the above problems. UTILITY MODEL CONTENTS
