Problems solved by technology

[0002] The field rapid measurement technology of surface micromorphology is the key to carry out soil erosion research. At present, methods such as filling volume method and laser scanner are generally used for surface micromorphology measurement, which are difficult to meet the requirements of quantitative morphological measurement and convenient and rapid field measurement.
Among them, the filling volumetric method has a large workload and can only estimate the volume, which cannot reflect the shape and size of the eroded surface. In recent years, relatively large-scale laser scanners have been tried to measure the micromorphology of the surface, but because of their scanning During the measurement process, its accuracy is affected by the vegetation on the soil surface. In addition, the instrument is complex, cumbersome to observe, and bulky and difficult to move. It is extremely inapplicable and very difficult

Embodiment Construction

[0016] Embodiment 1 of the present invention includes vertical bars 1 arranged on both sides and horizontal bar members 2 arranged horizontally between the vertical bars, and the feature is that: the horizontal bar member 2 is densely covered with a row of vertical through holes 3 at equal intervals A row of equal-length benchmark posts 4 are correspondingly pierced through the vertical through holes 3, and scale marks 8 are also provided on the vertical bars on both sides.

[0017] The scale value 5 of the above-mentioned scale line 8 is arranged on the surface of the vertical bar from top to bottom; the length of the above-mentioned benchmark bar is equal to the distance from the position of the zero scale value line on the vertical bar to its bottom end surface, and the scale value is marked from top to bottom from zero , at this time, the scale value corresponding to the endpoint on the pole is the depth value of the depression, and the measurer can easily read and record t...

Abstract

The invention relates to a surface micro-morphology measuring device and the use method, comprises vertical bars which are arranged at the two sides and a transverse member which is transversely arranged between the vertical bars, and is characterized in that the transverse member is densely covered with a row of equal-space vertical through holes, in the vertical through holes a row of equilong sign posts are accordingly arranged, and the vertical bars at the two sides are provided with graduation marks. The invention is characterized not only by simple structure and convenient carrying, but also by low manufacture cost; the operation of two measure methods provided by the invention is very simple and convenient, in particular to a second measure method which can greatly increase field measure speed and provide convenience for field surveying work.

Description

Technical field: [0001] The invention relates to a device for measuring the micromorphology of the ground surface and its application method. The device and the application method are especially used for the measurement of small depressions formed by rainwater scouring mountains or agricultural land. Background technique: [0002] The field rapid measurement technology of surface micromorphology is the key to carry out soil erosion research. At present, methods such as filling volume method and laser scanner are generally used for surface micromorphology measurement, which are difficult to meet the requirements of quantitative morphological measurement and convenient and rapid field measurement. Among them, the filling volume method has a large workload and can only estimate the volume, which cannot reflect the shape and size of the eroded surface; in recent years, a relatively large laser scanner has been tried to measure the micromorphology of the surface, but because of it...
