Description
Technical Field
[0001] The utility model relates to the technical field of forestry, in particular to a forestry area measuring device which is easy to fix. Background Art
[0002] Forestry area refers to the land area used for forestry production purposes, including various types of land such as forested land, sparse woodland, shrubland, unforested afforestation land, and nursery land. It is an important indicator to measure the scale of forest resources and forestry development space in a region. Canopy density refers to the degree to which the crown of trees in the forest covers the ground. It is an indicator reflecting the density of the forest stand. The size of the forestry area is directly related to the stability of the ecosystem. Forests can conserve water resources. For example, in mountainous areas, large areas of forests are like a huge "green reservoir". The roots of trees can fix the soil and prevent soil erosion. The roots of each tree can be closely integrated with the soil. The forestry area provides the basis for timber production. In a reasonably planned forestry area, through scientific logging and reforestation, timber resources can be continuously provided for use in many industries such as construction and furniture manufacturing.
[0003] The field measurement method utilizes various measuring tools, such as GPS measuring instruments and total stations. For regularly shaped woodlands, such as rectangular artificial afforestation land, the length and width can be directly measured to calculate the area. Existing GPS measuring instruments measure the surrounding environment through a central unit. The support arm length of the GPS measuring instrument is generally fixed, and only the opening and closing angle of the support arm can be adjusted to change the measurement height. However, on some uneven terrain, the opening and closing angle of the support arm is too large, causing the measuring instrument to shake and affecting the measurement effect. Utility Model Content
