Description

Technical Field

[0001] The invention relates to the technical field of deep-sea ecological restoration, and in particular to a method for placing and recovering a biological attachment base substitute for deep-sea mining ecological restoration. Background Art

[0002] Deep-sea mining activities have attracted much attention due to their value in obtaining scarce resources, but the damage to the deep-sea environment caused by mining activities is also increasingly attracting attention. The deep-sea ecosystem is more fragile and complex than the shallow sea environment. The growth rate of the seabed biological community is slow, and the natural repair capacity after external interference is limited. Therefore, effective ecological restoration after mining activities has become an important task. Among them, the use of biological attachment base substitutes for deployment and restoration is one of the important methods of deep-sea ecological restoration. It aims to promote the attachment of microorganisms, algae and other organisms through artificial structures, and gradually restore the function of the seabed ecosystem.

[0003] However, existing deep-sea ecological restoration technologies have many shortcomings and are difficult to meet the special requirements of the deep-sea environment. Traditional biological attachment base deployment technology lacks precise positioning and dynamic correction capabilities, and is easily caused by the complex ocean currents, terrain and deployment equipment errors in the deep sea, resulting in deployment position deviation, which reduces the accuracy and stability of the restoration. In addition, existing attachment bases usually adopt a single material release mode and microstructure design, which is difficult to meet the biological attachment needs of different ecological levels at different depths, resulting in a single restoration effect and lack of long-term effectiveness. At the same time, existing technologies are insufficient in sediment coverage and structural damage detection and maintenance, and lack real-time self-cleaning and structural adjustment functions, which affects the long-term stability and biocompatibility of restoration materials in the deep-sea environment.

[0004] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a method for placing and recovering a biological attachment base substitute for deep-sea mining ecological restoration, thereby ensuring its long-term effectiveness and adaptability in the deep-sea environment, thereby better supporting the sustainable restoration of the deep-sea ecosystem.
