Abstract
The invention discloses a kind of method that MINI super-station instrument demarcates permanent sample plot.This invention is to utilize MINI super-station instrument for survey tool, designs requirement according to permanent sample plot, determines permanent sample plot central point O to be built, permanent sample plot inceptive direction and permanent sample plot area S.In forest land, demarcate four permanent sample plot boundary points successively, finally set up square permanent sample plot through checking.
Description
One, technical field
The present invention relates to a kind of method that permanent sample plot is demarcated, particularly a kind of with MINI super-station instrument for survey tool demarcation
The method of permanent sample plot.
Two, technical background
Permanent sample plot investigation is the important foundation sex work of National Forest resource and ecological environment comprehensive monitoring and evaluation.Closely
Monitoring technology, means and the index body that over Nian, Chinese scholars active adoption 3S (GPS, GIS, RS) technical perfection is new with development
System, and embark quick, effective, multiple functional technology platform.Up to the present, permanent sample plot is demarcated and is relied primarily on sieve
Dish, total powerstation, the equipment such as GPS.But permanent sample plot demarcated by compass and tape measure, needs scaled distance in gradient larger area, than
Cumbersome, total powerstation weight ratio is relatively big, sets up instrument in forest land and is also required to relatively flat landform, has certain limitation, GPS
Equipment is in the forest land that coverage is bigger, and jitter even cannot receive gps signal.Therefore, finding one can be fast
The easy method demarcating permanent sample plot of speed is particularly important.
Three, summary of the invention
In order to overcome deficiency and the limitation using traditional instrument and method to demarcate permanent sample plot existence in forest land, with
Method demarcates permanent sample plot in forest land the most fast and efficiently, the invention provides a kind of MINI super-station instrument and demarcates permanent sample plot
Method.
The object of the present invention is achieved like this:
(1) design requirement according to permanent sample plot, determine permanent sample plot central point O to be built, sample ground inceptive direction and sample ground
Area S;
(2) in permanent sample plot to be built, dispose MINI super-station instrument in permanent sample plot central point O, horizontally rotate instrument and make
Its alignment sample ground designs inceptive direction and by instrument magnetic azimuth zero setting, utilizes instrument distance measurement function, and demarcating distance isConsolidate
Random sample boundary point A;
(3) instrument magnetic azimuth being sequentially adjusted in is 90 °, 180 °, 270 °, and demarcation distance is successivelyFixing sample
Boundary point B, C, D;
(4) instrument stand is located at A point, measures distance d of AB1Distance d with AD4, then, instrument stand is located at C point and measures
Distance d of CB2Distance d with CD3;
(5) digital-to-analogue is utilizedCalculate mis-tie misclosure K, ifThen repeat the above steps
Re-scale four boundary's points of permanent sample plot, untilIfThen A, B, C, D are permanent sample plot circle point, four points
It is sequentially connected with the square surrounded and is the square permanent sample plot that area is S.
This invention has the advantage that
1. utilize MINI super-station instrument to demarcate permanent sample plot, be easily carried, set up simple, can well be suitable for different terrain,
Facilitate staff;
The most only need to set up an instrument, the demarcation of permanent sample plot four circumference point can be basically completed, improve work efficiency;
3. can quickly check permanent sample plot precision, improve the reliability demarcating permanent sample plot.
Four, accompanying drawing explanation:
The present invention is further described with example below in conjunction with the accompanying drawings.
Fig. 1 is that MINI super-station instrument demarcates permanent sample plot schematic diagram;
Five, detailed description of the invention:
For demarcating the problem of permanent sample plot in forest land, the present invention has had bigger on way of thinking of theories and operating process
Ground improves and innovation, it is provided that a kind of MINI super-station instrument demarcates the method for permanent sample plot, specifically:
(1) as it is shown in figure 1, design requirement according to permanent sample plot, permanent sample plot central point O to be built, permanent sample plot are determined
Inceptive direction and permanent sample plot area S;
(2) in permanent sample plot to be built, dispose MINI super-station instrument in permanent sample plot central point O, horizontally rotate instrument and make
Its alignment sample ground designs inceptive direction and by instrument magnetic azimuth zero setting, utilizes instrument distance measurement function, and demarcating distance isConsolidate
Random sample boundary point A, i.e. the distance of OA is
(3) repeating step (2), instrument magnetic azimuth being sequentially adjusted in is 90 °, 180 °, 270 °, and demarcation distance is successivelyPermanent sample plot circle point B, C, D;
(4) instrument stand is located at A point, measures distance d of AB1Distance d with AD4, then, instrument stand is located at C point and measures
Distance d of CB2Distance d with CD3;
(5) digital-to-analogue is utilizedCalculate mis-tie misclosure K, ifThen repeat above-mentioned step
Suddenly four boundary's points of permanent sample plot are re-scaled, untilIfThen A, B, C, D are permanent sample plot circle point, four
Point is sequentially connected with the square surrounded and is the square permanent sample plot that area is S.
(6) when replacement and fixation sample ground in future, according to step (4) and step (5), permanent sample plot mis-tie misclosure K is calculated, ifThen need to re-scale demarcation four boundary's points of permanent sample plot, untilIfThen use initial construction
Square permanent sample plot.
Claims (1)
