A soil profile measurement method and equipment based on gis and double-layer neural network

Abstract

The invention discloses a soil profile measurement method and equipment based on GIS and a double-layer neural network, belonging to the technical field of geochemical prospecting and prospecting, and is used to solve the problem that the layout position and line spacing of the existing soil profile measurement are difficult to be determined, and multiple constructions are required. The soil profile consumes manpower, material resources and high laboratory costs, and the line spacing is too large, which leads to the technical problem that the soil profile cannot fully display abnormal characteristics. The method includes: on the basis of systematic sampling, analysis and testing, using a small amount of implemented soil profiles and sampling analysis data as training samples, through the trained double-layer BP neural network model, multiplying the point distance according to the preset line distance, and interpolating and encrypting several Strip soil profiles and sampling points to increase the amount of information in the analysis data, and then make a horizontal profile of the main metallogenic elements based on the laboratory analysis data and predicted data, and then connect the peak areas on the horizontal profile to form an abnormal long axis of elements , combined with topographic maps and remote sensing images, to determine the target trenching location.

Description

technical field [0001] This application relates to the field of geochemical prospecting, in particular to a soil profile measurement method and equipment based on GIS and double-layer neural network. Background technique [0002] Soil geochemical survey, referred to as soil survey, has already become an important means in the geological and mineral general survey, detailed survey of mining areas, mine spot inspection and regional geochemical anomaly inspection. By ascertaining the geochemical distribution characteristics of elements in the soil, delineating geochemical anomalies, carrying out mineral exploration, resource evaluation, ecological environment investigation, soil quality geochemical evaluation and basic geological research, it will contribute to the economic and social development of geological minerals, agricultural ecological environment, etc. aspect application services. [0003] Among them, mineral exploration has important guiding significance for mineral ...
