Description
Technical field
The present invention relates to a kind of measuring method of ditch head morphology, be specifically related to the method for the monitoring of a kind of small-sized coombe ditch head morphology and erosion amount.
Background technology
China loess plateau, northeast black soil region, Jinsha jiang River dry-hot valley are distributed with the vast coombe of area; The ravinement amount is big, cutting speed is fast; Not only nibble the arable land; Also damage road, quicken the land deterioration process, ravinement research is of far-reaching significance to rivers Sediment Control and local economy sustainable development.
The Erosion and Sediment Production effect is key one ring of ravinement research, and present stage research generally adopts the method for small watershed silt monitoring to carry out, but how quantitatively the sediment production of domatic, the furrow bank of identification, ditch bed does not still have simple, reliable way at present.As Ding Wenfeng etc. " application of landform chaining pin plate in slope soil erosion research " " delivered (Chinese water and soil conservation; 2006 (1): 49-51) use the landform chaining pin in the literary composition and harden and close related software and make the 3 dimensional drawing before and after the erosion caused by sloping surfaces; reflected the erosion amount size at position, domatic variant space more intuitively; but, can't be applied in the runoff plots soil erosion experimental study of field than large scale because the limitation of landform chaining pin plate itself (specification little, can only be used for the indoor water tank experiment of width) less than 50cm; " the high-precision GPS that Zhang Peng etc. are delivering; The comparative study of three kinds of measuring techniques of 3 D laser scanning and chaining pin plate monitoring rill erosion process " in the literary composition, applying three-dimensional laser scanning method monitoring slope rill erosion growth course, the result shows; Laser scanner can be monitored the rill erosion evolution process well; And higher, but, limit its widespread use because three-dimensional laser scanner costs an arm and a leg, inconvenience is carried in survey crew technical requirement height, field to the erosion amount estimation precision.
Summary of the invention
One of the object of the invention be to provide a kind of simple, measure the monitoring method of coombe ditch head morphology and erosion amount accurately.
The present invention is achieved in that
The monitoring method of a kind of coombe ditch head morphology and erosion amount comprises the steps:
At first, the microtopography measurement frame is put two corrode between the stake, and guarantee that the microtopography measurement frame can cover the main erosion areas of ditch bed;
Secondly, the corrosion resistant plate of a bar shaped surface smoothing, wide about 5cm is put into two corrodes in the stake, as two straight lines that corrode in the surface level that stake fixes;
Once more, rise with an amount of brick and eggshell china brick four drift angle pads with the microtopography measurement frame, adjacent till the corrosion resistant plate up to microtopography measurement frame upper surface;
At last, the microtopography measurement frame is carried out leveling, up to four limits of microtopography measurement frame all till the level with surveyor's staff;
Wherein, Described microtopography measurement frame is made up of the grid surface that two-layer secured in parallel is arranged, the number of grid of two-grid face size and each grid surface is identical; And two grids on the same tested point on the face of two-grid up and down of correspondence, its vertical projection can overlap fully.Between the two-grid face through be positioned on the grid surface limit with the angle on support column be fixedly connected; Said grid surface is iron grid surface, and grid is made up of iron wire; Vertical range between the said two-grid face is 15cm to 25cm; Said grid surface is the rectangle grid surface, and the grid surface specification is 2m * 1m; The mid point on each limit of said grid surface is fixedly connected with the steel bar of two right-angled intersections; Steel bar is held grid, is out of shape in long-term use to prevent grid; Said grid is a square net, and the sizing grid specification is 2.5cm * 2.5cm;
Steel ruler is vertically inserted in the double layer grid of microtopography measurement frame; Steel ruler all is close to the same angle in the grid during each the measurement; Measure the distance of coombe ditch head (gathering ground, furrow bank or the ditch bed) face of land and microtopography measurement frame upper strata frame respectively, be designated as the Z value of this net point;
Each microtopography is measured in the planar survey process; The microtopography measurement frame coordinate on following an of left side is decided to be (0,0, Z); By that analogy, according to getting a characteristic (surveying 1 point) in each grid interval distance and the measuring process, obtain the coordinate (X, Y, Z) of each net point at a distance from several grids;
Scheme further is: in order to ensure corroding the stake top on same surface level; Adopt following method: fixing earlier one corrodes stake; Squeeze into another at opposite side again and corrode stake, in the process of squeezing into, need be put into two to wide 5cm, corrosion resistant plate that length is enough and corrode on the stake tops; Carry out leveling with surveyor's staff; Till the level angle at each position of corrosion resistant plate is zero degree, can confirm two tops of corroding stake on same surface level, the reference planes that the microtopography measurement frame was put when this plane conduct was measured at every turn.
Scheme further is: in the step 2; After fixing the microtopography measurement frame for the first time; The mark and the data of record fixed position comprise: microtopography measurement frame upper surface mark its with the position of corrosion resistant plate coboundary contact point, and measure these two marks to a distance that corrodes; According to the position of these two marks and the fixing each test of range data back measurement frame, guarantee each measure regional identical.
Scheme further is: the concrete grammar of the form of said measuring and calculating coombe ditch head is:
In
each terrain data input Excel form of measuring; According to getting a characteristic (surveying 1 point) in microtopography measurement frame grid order and the measuring process measurement grid (X is set at a distance from several grids; Y, Z) value;
The calculating of
monitoring period gathering ground, furrow bank, ditch bed soil erosion amount, the spatial volume during with monitoring period starting point between the ditch bed face of land and the microtopography measurement frame upper epidermis is calculated as example:
Same quadrat method, the spatial volume of the segment endpoint ditch bed face of land and microtopography measurement frame upper epidermis when obtaining monitoring, the difference of two volumes is the soil erosion amount of monitoring ditch bed in this time monitoring period.
Use method of the present invention, can carry out the monitoring of small-sized coombe ditch head morphology very easily, and measurement result is accurate, the microtopography measurement frame that the present invention adopts is simple in structure, has stronger application value.The form monitoring and the soil erosion amount that are suitable for the small-sized coombe ditch head of field or lab simulation calculate.Especially utilize the microtopography measurement frame; Because the microtopography measurement frame is provided with up and down the corresponding mesh overlay alignment on a determining deviation, two grid surfaces between the grid surface, what guarantee that in measuring process steel ruler is contacted with vertically that the face of land to be measured and different time measure is same location point; And can make the coordinate system of measurement data, utilize Arcgis software deal with data easily, obtain test front and back soil erosion amount; Utilize Surfer software to obtain coombe ditch head microtopography exterior view, show that more intuitively microtopography changes.
