Description
Technical field
The utility model relates to the tools of vegetation sample investigation, and in particular to a kind of sample prescription ruler.
Background technique
Vegetation coverage is invaded as an important ecological index in bio-diversity, land deterioration and recovery and soil
It is widely used in the researchs such as erosion model.The method for extracting vegetation coverage with remote sensing image in large scale is very common, but
The acquisition of remote sensing image suffers from limitation, and obtained information is an integral value, does not consider regional differentiation.?
The most commonly used is the vegetation coverages in small scale sample prescription in practical study.
Sample prescription be can representative sample information characteristics basic sampling unit, for obtaining the essential information on sample ground.At present
China still lacks effective tool in terms of vegetation investigation, and conventional survey is using four edge lengths of tape measure amount and in four corner mark posts
It pinpoints, without very specific boundary between each point, it is difficult to ensure that the accuracy of sample investigation.And common pole does boundary, too
It is long then inconvenient to carry, it is too short, it is not able to satisfy the demand of investigation quadrat size.And four angles successively pinpoint also it is difficult to ensure that
Sample prescription is just square.There is no scale, layman is inconvenient to use.

A kind of sample prescription ruler includes four flat bars 1, several elbows 2 and at least one three-way elbow 3；Flat bar 1 by elbow 2 or/
It is rectangular at least one 3 connection group of three-way elbow.
Further, the sample prescription ruler further includes day-mark bar 4, and one end of day-mark bar 4 is connect with three-way elbow 3.
Further, the flat bar 1 is connected from beginning to end by the flat bar unit 5 of several segments and is formed.
Further, the flat bar unit 5 is hollow pipe, is connected between flat bar unit 5 by interconnecting piece 5-1；Interconnecting piece
5-1 can pack into the both ends of flat bar unit 5.
Further, the day-mark bar 4 is connected from beginning to end by several segments day-mark bar unit 6 and is formed.
Further, 6 hollow pipe of day-mark bar unit is connected by interconnecting piece 5-1 between day-mark bar unit 6；Connection
Portion 5-1 can pack into the both ends of day-mark bar unit 6.
Further, scale and/or reading are provided on the day-mark bar unit 6.
Further, the day-mark bar unit 6 is set as different colors.
Further, the flat bar unit 5 and day-mark bar unit 6 can be general.
Sample prescription ruler provided by the utility model is made of flat bar, elbow, three-way elbow, interconnecting piece and day-mark bar.It does not use
When each section can be dismantled, it is convenient for collecting and carry.Tool needs to assemble when use, and assembling is simple.
Compared with prior art, sample prescription ruler provided by the utility model has the advantage that
(1) structure is simple, portable.
(2) it installs, is easy to use.
(3) adjustable size.
(4) applied widely.
