Abstract
The invention discloses a kind of method that MINI super-station instrument determines any seeds volume of timber without Volume table.The present invention is the method about forest inventory investigation, and it belongs to a kind of nothing and cuts down the volume of timber measuring method of lossless trunk.It is characterized in that: measure tree-walk d at standing tree height of tree H and 1/2H with MINI super-station instrument for instrument, try to achieve the volume of timber of goal tree finally by important actor method.This method takes full advantage of MINI super-station instrument precision height, the flexible and feature of low cost, reduces the cost of field investigation, improves the operation of standing volume field survey and the efficiency of interior industry process.It is demonstrated experimentally that this method can substitute felled tree sectional measurement completely.
Description
One, technical field
The present invention relates to a kind of method measuring standing volume, particularly a kind of MINI super-station instrument determines without Volume table appoints
The method of the meaning seeds volume of timber.
Two, technical background
Forest growing stock is to identify the leading indicator of forest quantity.The size of unit stock volume indicates that forest land produces
The height of power and the effect of Operation Measures.But due to various factors such as area of woods are wide, trees quantity is big, by prepared in advance
Good tree volume table measures the standing volume of trees can bring to us that certainty of measurement is the highest, restrictive condition is many, complex operation
Deng inconvenience.In practice, forest workers has been used up cuting down normal wood acquisition and sets up the modeling sample needed for standing volume equation
This.Although this method precision is higher, but need trees are cuted down, forest reserves damage too greatly and is not met protection life
The objective of state environment.
Along with maturation and the development of surveying and mapping technology, MINI super-station instrument is with the high and low cost of its precision, the application of portative advantage
In all trades and professions.The application in assize of the MINI super-station instrument, not only increases assize speed, precision and efficiency.The more important thing is
Forest need not be cuted down and climb tree, not having forest any infringement just can obtain factors of enumeration in real time.This method is exactly so
Background under produce.
Three, summary of the invention
For overcoming the measurement standing volume of traditional method to need known models, cuting down measurement destructiveness big, cost is high, work
The shortcomings such as efficiency is low, improve efficiency, it is achieved quickly resolve standing volume, the invention provides a kind of MINI super-station instrument without the volume of timber
Table determines the method for any seeds volume of timber.
The object of the present invention is achieved like this:
First, goal tree to be measured is selected；Then, utilize MINI super-station instrument to measure tree-walk d at standing tree height of tree H and 1/2H,
Footpath, note standing tree ground is d0, tree-walk is d at 1/4H1, tree-walk is d at 3/4H2, and standing tree meets relation: d0＞ d1=d ＞ d2；Finally,
Utilize digital-to-analogue 1. V=a d2H, wherein a=6.113 × 10-5, resolve the volume of timber V obtaining goal tree.
The invention have the advantages that
(1) substantially increasing the precision of related data, this research have employed high accuracy instrument of surveying and mapping MINI super-station instrument
Having the raising of the order of magnitude as metadata acquisition tool, relatively conventional measurement tree method precision, the data being achieved in that are as factors of enumeration
Data Source, is necessarily greatly improved the precision of these data；
(2) achieving the noninvasive measurement to trees, bottom class's normal wood is the most all taked to do analytic tree by traditional method
Approach, intricate operation, and forest is damaged.By MINI super-station instrument, forest need not be cuted down and climb tree, forest not had and appoint
What infringement just can obtain factors of enumeration in real time.This tries hard to recommend capable forest sustainable management policy seem for current China is honest
Particularly important.
Four, accompanying drawing explanation
The present invention is further described with example below in conjunction with the accompanying drawings.
Fig. 1 is stem volume segmentation Computing Principle schematic diagram of the present invention.
Five, detailed description of the invention:
Without Volume table, a kind of MINI super-station instrument determines that the method for any seeds volume of timber is different from traditional method, specifically exist
In:
(1) selecting goal tree, measure tree-walk d at standing tree height of tree H and 1/2H with MINI super-station instrument, footpath, note standing tree ground is d0、
At 1/4H, tree-walk is d1, tree-walk is d at 3/4H2, and standing tree meets relation: d0＞ d1=d ＞ d2；Utilize digital-to-analogue 2. y2=a xγ,
Obtain tree-walk relation:
(2) digital-to-analogue 1. V=a d is utilized2H, wherein a=6.113 × 10-5, resolve the volume of timber V obtaining goal tree.
Claims (1)
1. the method that MINI super-station instrument determines any seeds volume of timber without Volume table, is characterized in that: with MINI super-station instrument be
Tree-walk d at standing tree height of tree H and 1/2H measured by instrument, finally by the volume of timber V of important actor method solving target tree；Concretely comprise the following steps: first
First, goal tree to be measured is selected；Then, MINI super-station instrument is utilized to measure tree-walk d at standing tree height of tree H and 1/2H, footpath, note standing tree ground
For d0, tree-walk is d at 1/4H1, tree-walk is d at 3/4H2, and each section of tree-walk meet relation: d0＞ d1=d ＞ d2；Finally, number is utilized
Mould 1. V=a d2H, wherein a=6.113 × 10-5, resolve the volume of timber V obtaining goal tree.
