Abstract
A kind of production method of standing forest " three amounts " figure, it is characterized by: based on orthography captured by aerophotograph, interpretation is carried out to tree species, and extract standing forest relevant information, canopy density, accumulation, increment are carried out to standing forest according to formula to calculate, and finally make " three amounts " figure of every wood in regional scope.
Description
One, technical field
This method belongs to a kind of Canopy densities, accumulation, the calculating of increment and drafting method.
Two, technical background
Forest surveying is carried out using airphoto and Forestry Drawing is one of the main task of forest inventory investigation.Aviation picture
Piece is that the true color feature of ground forest really reflects and record have very high ground resolution and stable interpretation feature,
It is had very important effect in forest aerosurveying technology.It is carried out in the available forest survey of forest surveying using aerophotograph
Every quantification factor, specifically include that (1) stand facters, including standing forest area, canopy density, mean height degree, standing forest are raw
Long amount, stem-number and stand etc.；(2) the single standing tree factor, including the growth of standing tree height, hat width, the diameter of a cross-section of a tree trunk 1.3 meters above the ground, standing tree height
Amount, hat width increment etc..Aerophotograph interpretation is carried out under three-dimensional model, mainly identification stand characteristics, such as composition, standing forest
High, Canopy densities and standing forest boundary, and standing forest boundary is described under three-dimensional model, finally it is fabricated to forest classified
Figure.
Standing forest " three amounts " refers to closing measurement, accumulation and increment.Canopy density refer to that arbor tree crown is straight in sunlight in forest
Penetrate down the ratio of the total projection area and this standing forest gross area on ground；Accumulation is the sum of the volume of timber of all live standing trees in standing forest；
Increment is the increment of tree height, diameter and the volume of timber in trees or forest certain time, and wherein mean annual precipitation refers to forest
The quantity of annual average production during the entire age.Main body of the forest as biosphere, plays ecosystem balance important
Effect.Forest reserves and biomass are carried out using remote sensing technology, to the spatial distribution and Monitoring on Dynamic Change of forest species
It is of great significance.
Three, summary of the invention
A kind of production method of standing forest " three amounts " figure, it is characterised in that: based on orthography captured by aerophotograph, to tree species
Interpretation is carried out, and extracts standing forest relevant information.It carries out canopy density, accumulation, increment to standing forest according to formula to calculate, most
" three amounts " figure of every wood in regional scope is made eventually.
The invention has the following advantages that
1. standing forest " three amounts " figure can intuitively reflect forest structure, forest environment and tree growth situation.
2. reducing artificial field process amount to the interpretation of tree species and other factors according to orthography.
3. the thinking proposed is easily understood, actual mechanical process is easy to operate, and there is no training and learning difficulties.
Four, Detailed description of the invention:
Nothing.
Five, specific embodiment:
The present invention provides a kind of new resolving thinkings and mode, specifically:
1, R=1 hectares of ranges are selected in forest as sample, which is shot, and what is obtained is high-resolution
Just penetrate
Image is simultaneously corrected.
2, tree species are identified and distinguished between on airphoto.First have to existing ground on-site survey interpretation forest zone tree families,
Shape is special
Sign, habit and the regularity of distribution, then according to shape of tree-crown and size, tree crown tints and shades, tree species point
Cloth rule
The factors such as rule carry out observation comparison, and final interpretation goes out tree species.
3, the projected area S of each tree is soughti, according to formulaIt calculates Canopy densities and charts.
4, according to the tree species of interpretation and diameter of a cross-section of a tree trunk 1.3 meters above the ground di, hat width Di, according to formulaIt calculates accumulation and charts.
5, according to formulaThe difference of 2 years diameters of a cross-section of a tree trunk 1.3 meters above the ground is Δ di, the difference of 2 years accumulations is Δ
Mi, obtain stand growth and chart.
Claims (4)
1. a kind of production method of standing forest " three amounts " figure, it is characterised in that: based on orthography captured by aerophotograph, to tree species into
Row interpretation, and extract standing forest relevant information；It carries out canopy density, accumulation, increment to standing forest according to formula to calculate, finally
Make " three amounts " figure of every wood in regional scope.
2. a kind of production method of standing forest " three amounts " figure according to claim 1, canopy density calculation method are as follows: according to formulaThe projected area of each tree is Si, calculate Canopy densities.
3. a kind of production method of standing forest " three amounts " figure according to claim 1, accumulation calculation method are as follows: according to formulaThe diameter of a cross-section of a tree trunk 1.3 meters above the ground is di, hat width Di, calculate accumulation.
4. a kind of production method of standing forest " three amounts " figure according to claim 1, increment calculation method are as follows: according to formulaThe difference of 2 years diameters of a cross-section of a tree trunk 1.3 meters above the ground is Δ di, the difference of 2 years accumulations is Δ Mi, obtain stand growth.
