Soil erosion rate monitoring method

Abstract

The invention discloses a soil erosion rate monitoring method which comprises the following steps: (1) mounting a plurality of erosion scaleplates having the same structure in a to-be-detected area and numbering the erosion scaleplates sequentially, wherein each erosion scaleplate comprises a fixed ruler and a sliding ruler movably mounted on the fixed ruler, the fixed ruler is vertically mountedon soil, zero scale of the sliding ruler is aligned to the top of the fixed ruler, a scale is marked on the zero scale of the sliding ruler upward; (2) reading data according to the monitoring time and the number, wherein the data is data where the sliding ruler is located at the top of the fixed ruler; (3) calculating the soil erosion amount according to the read data. By arranging the erosion scalplates as the fixed rulers and the sliding rulers, the erosion data of soil can be read easily according to the sliding distances of the sliding rulers, and the soil erosion rate is calculated quickly according to the soil erosion data, so that the soil erosion amount is calculated quickly and precisely. Meanwhile, the method is suitable for water erosion and wind erosion.

Description

technical field [0001] The invention relates to a soil erosion rate monitoring method, which belongs to the field of soil erosion monitoring Background technique [0002] my country is one of the countries with the most serious water and soil erosion in the world. At present, the area of ​​water and soil erosion in my country reaches 3.5692 million square kilometers, and the economic loss caused by water and soil erosion reaches hundreds of billions of yuan every year. Soil erosion is a basic form of surface material migration, and it is also one of the major environmental problems facing the world today. The related research on soil erosion mechanism, erosion rate monitoring and control countermeasures has become an important research content in the fields of geosciences and biology. It has been an important research topic for soil and water conservation workers for a long time. [0003] The existing soil erosion rate monitoring methods for field observation mainly include...

Problems solved by technology

However, for a long time, the production of erosion needles has not yet formed a standardized standard, and the corresponding measurement tasks need to be completed with the help of traditional measurement work, which cannot solve the problem of exposed or buried erosion needles, resulting in large measurement errors and workload, especially for vegetation coverage. Low monitoring sample plots cannot avoid human disturbance on the ground surface, which will affect the measurement accuracy
