Problems solved by technology

[0003] ①In actual work, the whole-forest field measurement method is time-consuming and labor-intensive, and it is only used in special needs such as surveys and scientific experiments in small forest stands
[0004] ②The visual method uses tree measuring instruments and tree measuring tables as auxiliary means to estimate the stand volume, and there is a large uncertainty
[0005] Therefore, in the continuous inventory of national forest resources, when using the traditional measurement method and visual method to measure the stand volume, it will inevitably bring a lot of trouble and the accuracy is not high and the efficiency is low.

Embodiment Construction

[0035] The method of measuring forest stand volume based on mobile phones is different from the existing methods and has been greatly improved. Specifically: using an ordinary mobile phone as a tool, install a software with tree measuring function in the mobile phone, and set the opening angle θ of the tree measuring software to 1°08′45″. Use this opening angle to aim at the diameter at breast height of the tree, and from the sample Measure 360° around the point, and observe the height of the trunk at the trunk tangent to the trunk above the chest height, expressed with h. The method for calculating the stand volume is as follows: the volume per hectare (M) is equal to the height of each tree observed on the forest floor The sum of the heights of all tree trunks from the ground (in m), namely:

[0036] The specific implementation is as follows:

[0037] 1. Install the tree measuring software in the ordinary mobile phone. The functions of the software include setting the ope...

Abstract

The invention discloses a method for directly determining the stand volume with a mobile phone, wherein the method comprises the following steps: determining the number and volume of trees in a forest stand per unit area by an angle gauge method; taking an ordinary mobile phone as a tool, setting angle gauge factors in mobile phone tree-measurement software; when certain angle gauge factor Fg is used, measuring around 360 degrees from sampling points, and observing heights of trunks above the ground, wherein the trunks are at places where the angle gauge notch is just tangent to the trunks above the breast height; the method for calculating the stand volume is as follows: the volume per hectare (M) is equal to the sum (in m) of heights of the trunks at all tangent places of each observed tree on the forest land above the ground multiplied by the angle gauge factor (referring to the Specification for the formula).

Description

1. Technical field [0001] The invention relates to a method for measuring stand volume in forest resource investigation, in particular to a method for directly measuring stand volume with a mobile phone. 2. Technical Background [0002] In the traditional forest resource monitoring, the measurement of stand volume has always been a difficult problem, and the actual measurement method and visual method are usually used to measure the stand volume. The actual measurement method can be divided into the whole forest actual measurement and the local actual measurement, and the methods for determining the stand volume can be further divided into the standard wood method and the numerical table method. But the traditional technology has obvious shortcomings and deficiencies: [0003] ①In actual work, the whole-forest field measurement method is time-consuming and labor-intensive, and it is only used for special needs such as surveys and scientific experiments in small forest stand...
