Abstract: Disclosed are a method and a system for forecasting an agricultural product price based on signal decomposition and deep learning. The method includes: S1, obtaining price subsequences by performing a complementary ensemble empirical mode decomposition (CEEMD) on an original price sequence of agricultural products; S2, obtaining a reconstructed sequence based on the price subsequences; S3, obtaining data features of the reconstructed sequence based on the reconstructed sequence; and S4, constructing a Bi-directional Sequence to Sequence (BiSeq2seq) model, and inputting the data features of the reconstructed sequence into a CCS-Bi-directional Sequence to Sequence (CCS-BiSeq2seq) model to obtain a forecasting result.

Abstract: A method for ecological disturbance risk identification and assessment based on automatic parameter adjusting optimization model is disclosed. The method includes: establishing a three-layer ecological disturbance risk assessment index system based on an ecological disturbance risk identification and assessment function, performing normalization preprocessing on the assessment indexes, screening the assessment indexes meeting a multicollinearity judgement interval based on variance inflation factor method, establishing an ecological disturbance risk assessment model, optimizing weight parameters of the ecological disturbance risk assessment model based on particle swarm optimization algorithm to obtain an optimal solution of the model weight, and outputting a result of the risk index of ecological disturbance.

Abstract: A human activity recognition fusion method and system for ecological protection red line is disclosed. The method includes: obtaining a pre-stage remote sensing image and a post-stage remote sensing image of a target ecological protection red line region, and performing a data pre-processing; inputting the pre-processed pre-stage remote sensing image and the post-stage remote sensing image into a human activity recognition model after a pre-training; identifying a human activity pattern of the target ecological protection red line region as a first detection result; segmenting, calculating and analyzing the latest image data corresponding to the target ecological protection red line region based on a geographical country situation data to obtain a change pattern as a second detection result; and fusing the first detection result and the second detection result to obtain a change detection pattern of the target ecological protection red line region.
