A Classification Method of Offshore Sediment Grain Size Based on Spectral Technology

Abstract

The present invention is a method for classifying the particle size of offshore sediments based on spectrum technology. The steps are as follows: S1. Obtain samples of offshore sediments with different particle sizes and collect spectra; S2. Divide the full spectrum of offshore sediments into m bands, Establish the particle size model of offshore sediments for each band; S3. Select n optimal models from m offshore sediment particle size models, and use the fusion algorithm for fusion processing to obtain the optimal Classification result; S4. The n optimal models and fusion algorithm used in the obtained optimal model are used as the model and method for the particle size classification of offshore sediments to predict the particle size of unknown offshore sediments. The invention breaks the original particle size analysis method, reduces the time for traditional method of marine sediment particle size measurement, realizes the prediction of offshore sediment particle size classification quickly and non-destructively, provides a theoretical basis for searching for sediment characteristic bands, and provides a theoretical basis for particle size analysis. The division provides a solution.

Description

technical field [0001] The invention belongs to the field of particle size classification of offshore sediments, and in particular relates to a method for classifying the particle sizes of offshore sediments based on spectral technology. Background technique [0002] Marine sediments are the medium and carrier of the interaction between the hydrosphere, biosphere and lithosphere, and record detailed information on processes such as sea and land changes and depositional environment changes. The particle size of sediments is closely related to the source of sediments and depositional environment, and it is a common method to study the characteristics of sediments and depositional environment. Therefore, the analysis of different particle sizes of offshore sediments is of great significance to the study of sediments. Traditional particle size measurement techniques generally include direct measurement, sieve analysis, binocular microscopy, sedimentation and electron microscopy...
