Abstract
The invention relates to a method for measuring a wood volume of stumpage by using a novel breast height form factor. The method for measuring the wood volume of the stumpage by using the novel breast height form factor uses an electronic theodolite as a tool to design the novel breast height form factor, the wood volume, the diameter at breast height and the height of the stumpage are measured through the electronic theodolite, parameters in a novel breast height form factor model and a wood volume model are determined, and the wood volume of the stumpage can be rapidly determined according to the models. The method for measuring the wood volume of the stumpage by using the novel breast height form factor improves the calculation speed and accuracy of the wood volume of the stumpage, and overcomes the defects that the parameters involved in traditional calculation and measurement of the wood volume of tree trunks are many and the accuracy is not ideal.
Description
One, technical field
The present invention relates to a kind of method that uses novel artificial form factor to measure standing volume, the novel artificial form factor method stem volume instrumentation that particularly to utilize electronic theodolite be instrument.
Two, technical background
Traditional trees volume of timber measuring method is numerous, and majority, based on the hole Stem curve that hereby stem curve is derived, utilizes average section to amass publicity and the models such as approximation integration formula, central basal area approximation integration formula, newton's approximation integration formula, and felled tree is carried out to sectional measurement.In order to try to achieve standing volume, introduce the formula such as figurate number, form quotient and asked calculation.These method shortcomings are numerous.Although felled tree is distinguished and asked standing volume precision higher, large to trees damage, the cycle is long, has high input; Standing volume need to be measured the parameters such as the height of tree, the diameter of a cross-section of a tree trunk 1.3 meters above the ground, the opposite position height of tree and diameter, obtains difficulty data, and especially in the forest of serious shielding, defect is a lot of especially.The standing volume being based upon on the basis of boat sheet interpretation etc. handwork is measured, and the cycle is long, and efficiency is low, and low precision can not adapt to the monitoring requirements to the forest reserves and ecologic environment far away.
So in traditional forest inventory investigation, the mensuration of standing volume is received the restriction of landform, instrument, method, make the surveying work amount of the forest volume of timber, low precision, is difficult to obtain fast promising result.The present invention obtains the standing tree parameter on appropriate seeds and rank, footpath by the several electronic theodolites that obtain, designed novel artificial form factor and volume of timber computing formula.Improve speed and the precision of obtaining standing volume, effectively improved the standing volume obtaining means in forest monitoring technology.
Three, summary of the invention
Many in order to improve in classic method volume of timber model desired parameters, the defects such as actual measurement trees volume of timber efficiency is low, low precision, the invention provides a kind of electronic theodolite is the standing volume measuring method of instrument, it is characterized in that: take electronic theodolite as instrument, design novel artificial form factor, measure standing volume, the diameter of a cross-section of a tree trunk 1.3 meters above the ground, the height of tree by electronic theodolite, determine the parameter in its new form-factor model, volume of timber model, can determine fast standing volume according to its model.Improve computing velocity and the precision of stem volume, overcome the parameter to be measured that stem volume instrumentation relates in the past many, the defect such as precision is undesirable.
Main summary of the invention:
1. design the novel artificial form factor of design of novel station scale;
2. the foundation of novel artificial form factor;
3. obtaining of the standing tree diameter of a cross-section of a tree trunk 1.3 meters above the ground based on electronic theodolite, the height of tree, the volume of timber;
4. standing volume model is set up.
This invention has the following advantages compared with the conventional method:
(1) improve the trunk diameter of a cross-section of a tree trunk 1.3 meters above the ground, volume of timber instrumentation work efficiency, in traditional stem volume measuring process, needed to use multiple survey instrument, need to be in conjunction with hand-kept, and can not arrival place be difficult to obtain data personnel.Electronic theodolite of the present invention obtains data and can only store, and utilizes software efficiently to process.It is effective combination of surveying instrument and forestry applications.
(2) realized the quick high accuracy of stem volume is measured, it is more that classic method measures desired parameters.The standing volume model of setting up by novel artificial form factor, only need to measure parameter of the diameter of a cross-section of a tree trunk 1.3 meters above the ground, can quick and precisely obtain its volume of timber value.
