Description

TECHNICAL FIELD

[0001] The utility model relates to the field of forestry exploration, and concretely relates to a vegetation sampling frame for forestry exploration. BACKGROUND

[0002] Forests, as the main body of terrestrial ecosystems, play an irreplaceable role in maintaining ecological balance and providing ecological services. They not only provide habitats for numerous wild animals and plants, but also play a key role in regulating the climate, conserving soil and water, purifying the air, and conserving water resources. For example, a mature forest can release a large amount of water into the atmosphere through transpiration, increasing air humidity and regulating local climate; its dense root system can fix soil and prevent soil erosion, reducing the occurrence of natural disasters such as mudslides. With the intensification of global climate change and human activities, forest ecosystems are facing many threats, such as deforestation, forest fires, and pest damage. In order to effectively protect and manage forest resources and timely grasp the dynamic changes of forest resources, forestry exploration work is particularly important.

[0003] In the process of forestry exploration, various vegetation needs to be sampled. Ordinary flowers and plants can be directly sampled using scissors, hoes and other tools, while for woody vegetation such as small trees and shrubs, their stems or branches are hard and difficult to sample by hand or other simple tools. Usually, a handsaw is used for sampling to facilitate subsequent analysis and research. However, when the sampling quantity is large, it is time-consuming and laborious to use a handsaw, resulting in low sampling efficiency. Therefore, we have made improvements and proposed a vegetation sampling frame for forestry exploration. SUMMARY
