[0006] In order to overcome the shortcomings of the traditional method of measuring the volume of standing trees that require a known model, the felling measurement is destructive, the cost is high, and the work efficiency is low, the efficiency is improved, and the volume of standing trees is quickly estimated. The present invention provides a method for quickly estimating the volume of standing trees. Methods

Embodiment Construction
[0016] A method for quickly estimating standing volume differs from existing methods in that:
[0017] 1) Select the target tree and measure the circumference L of the standing tree with a girth 0 , measure the standing tree perimeter L at the tree height h=1.51m 1 , and use the digital model① Calculate the difference ΔL between the two measured circumferences.
[0018] 2) If the target tree is a coniferous tree species, use digital simulation② Calculate the tree height H and volume V of the target tree.
[0019] 3) If the target tree is a broad-leaved tree species, use digital simulation③ Calculate the tree height H and volume V of the target tree.

The invention discloses a method for quickly estimating the volume of standing wood. Through employing a diameter tape as a tool, the method measures the perimeter of a ground diameter of the standing wood and the perimeter of a part which is located at a tree height of h (1.51m), and quickly estimates the volume and height of the standing wood according to a Kunze M. curvilinear equation.
Description
[0001] 1. Technical field [0002] The invention relates to a method for measuring the volume of a standing tree, in particular to a method for quickly estimating the volume of a standing tree. [0003] 2. Technical background [0004] Forest growing stock is an important index of forest ecological service function, largely represents the mature stage of forest growth and forest ecological vitality, and is also an important factor in the current hot issue of global warming. Therefore, it is of great significance to carry out monitoring and assessment of forest growing stock. Due to various factors such as vast forest area, large number of trees, and difficult operations, it takes a lot of resources to measure the growing volume of all trees to monitor the growing stock. In practice, the sampling theory is often used to establish the growing tree volume equation to evaluate forest growing stock. For many years, forestry workers have been using felling standard logs to obtain th...
