Description
Technical Field

Background
The method is characterized in that a natural resource part issues a natural resource investigation monitoring system construction overall scheme in month 1 in 2020, a natural resource layered classification model is constructed, and a concept of a ground surface matrix is provided. The ground surface matrix is a basic substance for inoculating and supporting various natural resources such as soil, forests, grasslands, water, wetlands and the like on the surface layer of the earth, and is also a main bearing body of the key zone of the earth. The accurate depiction of the physicochemical properties of the earth surface matrix has important significance for understanding the structural features of the key zone of the earth on the surface layer, the soil air permeability, the hydrologic communication mechanism and the like.
Compared with the sample collected under the destruction condition, the undisturbed surface matrix sample can be used for measuring the important physicochemical indexes such as volume weight, saturated water conductivity, porosity, capillary water holding capacity and the like, and is the core content of surface matrix investigation. The depth of investigation of the ground matrix is generally about 20m, and the ground matrix is mainly concentrated above the surface of the submerged water in the dead water period or the maximum depth reached by the root system of the vegetation in a part of the area to 50 m. Compared with the traditional soil investigation depth of 1m or 2m, the investigation depth of the surface matrix is deeper, and the surface matrix simultaneously comprises soil, weathered crust, bedrock and the like. Traditional soil sampling devices (such as a Luoyang shovel, a knapsack drill and the like) can only collect non-undisturbed soil samples with shallow burial depths and finer textures under destructive conditions. In the prior art, large pits are required to be dug for collecting undisturbed soil, then the undisturbed soil is manually taken out by adopting a cutting ring, but for a surface matrix sample with deeper sampling depth, the method has large workload and low efficiency. On the other hand, the surface matrix sample has larger burial depth, and the physicochemical indexes such as temperature, oxidation-reduction potential, nutrient, salt and the like of the surface matrix change in a gradient manner from the surface to the underground surface, and the indexes are extremely sensitive to environmental changes, so that the test after the sample is taken out causes great errors and uncertainty, and therefore, in-situ detection is needed.
