Abstract

The invention relates to a method and a system for evaluating a deep sea ecosystem by utilizing bioacoustic characteristics. The method comprises the following steps: acquiring acoustic signals of various organisms in a deep sea ecosystem; according to the acoustic signal, determining deep-sea organism types and the number of deep-sea organisms; training a neural network model according to the acoustic signal, the deep-sea organism type and the deep-sea organism quantity to obtain a trained neural network model; acquiring a deep-sea bioacoustic signal of the sea area to be measured; and inputting the deep-sea organism acoustic signal of the sea area to be measured into the trained neural network model for prediction to obtain the deep-sea organism variety and quantity of the sea area to bemeasured. According to the invention, a specific sea area can be observed for a long time, and the surrounding environment is not damaged.

Description

technical field [0001] The invention relates to the technical field of evaluation of deep-sea ecosystems, in particular to a method and system for evaluating deep-sea ecosystems using bioacoustic features. Background technique [0002] As human activities gradually expand from the near sea to the deep sea, especially the mining of deep sea mineral resources, it will inevitably have an impact on the deep sea environment. The impact of deep-sea mining on the underlying ecosystem is significantly greater than that on the upper ecosystem, so the impact on the underlying ecosystem is the focus of deep-sea mining environmental issues. At present, the research on the underlying ecosystem mainly relies on conventional scientific research methods, such as manned submersibles, unmanned remote-controlled submersibles with cables, optical drag bodies, TV grabs, biological trawls, etc., to photograph and sample underwater organisms. However, manned submersibles, unmanned remote-controll...
