Description

Technical field [0001] The present invention relates to the field of wind erosion monitoring, and in particular, there is a closing of a sliding automatic weighing. Background technique [0002] Soil wind erosion is the process of fluging, handling and stacking of wind on the ground surface soil particles or sand. Environmental issues such as sandstorms and land productivity caused by soil wind erosion are one of the new international communities to solve, especially in my country's drought, semi-arid, and some semi-moist areas, which are seriously affected by soil erosion. Sustainable development and social and economic stability in the above areas. [0003] The soil wind ethable refers to the difference in soil quality of wind to carry and deposit in a certain period of time, is an important indicator of regional wind erosion strength. The measurement of soil wind etch is the basis for working monitoring, wind erosion model verification and revision, wind erosion strength and h...

Problems solved by technology

This type of method has high measurement accuracy, but the measurement process is cumbersome, requiring a large number of observation points and long-term monitoring data, and establishing a wind erosion model according to the sand movement laws and environmental factors in different regions, and requires a large amount of manpower and material resources

[0008] In addition, there are methods such as element tracer method and particle size comparison method, which are not suitable for long-term field observation due to the disadvantages of high technical difficulty, high cost and poor scalability.

[0009] In summary, the existing field measurement of soil wind erosion mainly faces two problems: ① The measurement accuracy and the simplicity of the method. The accuracy of wind erosion field measurement is directly related to the follow-up work such as wind erosion process monitoring, wind erosion model verification and revision, etc. Due to the harsh climate environment in the wind erosion area, many factors not subject to human control, and large space-time variability, simple measurement tools such as brazing can not obtain accurate measurement data, and high-precision instruments and equipment are not conducive to It is portable and used in the field for a long time, and the installation and operation of the instrument are complicated, which is not conducive to the promotion of the measurement method

② The problem that automatic measurement cannot be realized. Existing instruments cannot effectively eliminate the fluid pressure generated by the wind, especially during heavy storms, the "wind pressure" will affect the weight sensor, thereby seriously affecting the weighing accuracy of sand and dust

It can be seen that the above-mentioned wind-sand flow observation technology in the prior art is difficult to achieve high-precision and high-time-resolution monitoring
