specific Embodiment 1

[0072] S1. Select the survey unit, download the topographic map, remote sensing image, rainfall erosivity factor layer database, soil erodibility factor layer database, canopy density / coverage database, and farming measures of the survey unit through local download or remote download The factor layer database, the vegetation coverage and biological measure factor layer database, the slope length factor layer database and the slope factor layer database are stored in the storage unit 25 .

[0073] According to the remote sensing image of the survey unit, the GPS navigation unit 23 is used to navigate to the vicinity of the survey unit, and the remote sensing image is the Google map of the survey unit or a map with a higher resolution.

specific Embodiment 2

[0136] The difference between specific embodiment 2 and specific embodiment 1 lies in the way of obtaining each factor and the way of generating the spatial distribution layer of soil loss in the survey unit.

[0137] Specifically, the storage unit 25 stores a spatial layer database of rainfall erosivity factors, a spatial layer database of soil erodibility factors, a layer database of engineering measures factors, and a layer database of farming measures factors by downloading locally or through a remote data server. , vegetation coverage and biological measure factor layer database, slope length factor layer database and slope factor layer database.

[0138] The spatial layer database of rainfall erosivity factors is the spatial vector layer of half-moon rainfall of the survey unit in recent years, the spatial layer database of soil erodibility factor is the spatial vector layer of soil erodibility factor of the survey unit in recent years, and the factor of engineering measu...

Abstract

A portable device for soil erosion field investigation comprises a shell, a control unit arranged in the shell, and a remote data server. The control unit comprises a data processing unit used for generating soil loss amount space distribution layers of an investigation unit, a parcel division unit used for dividing the investigation unit into a plurality of parcels, a storage unit, a communication unit and a GPS navigation unit for navigation, the parcel division unit, the storage unit, the communication unit and the GPS navigation unit are in communication connection with the data processing unit, and the data processing unit is in communication connection with the remote data server through a wireless network. The portable device can be used for scientifically and accurately completing soil erosion field investigation, directly generating the soil loss amount space distribution layers and visually and accurately reflecting the soil loss amount of the investigation unit.

Description

technical field [0001] The invention relates to a method for field investigation of soil erosion, in particular to a portable device and method for field investigation of soil erosion. Background technique [0002] Soil erosion refers to the process in which soil or soil parent material is destroyed, separated, transported and deposited under the action of external forces such as water and wind. Severe soil erosion not only causes the degradation of land resources that humans rely on for survival and is increasingly scarce, but also causes erosion of sediment. The siltation of rivers, lakes, canals and reservoirs increases the risk of flooding and pollutes water bodies due to the adsorption of a large amount of chemical fertilizer residues into the river network. At present, soil erosion has become the number one environmental problem in our country. Only by finding out the distribution, area and intensity of soil erosion in a certain area, and mastering the dynamics of soi...
