The application discloses a water ecological damage identification method based on eDNA scene adaptation selection, and the method is characterized in that: through systematic comparison of different eDNA collection methods from the aspects of species detection capability, morphological mapping rate, PCR amplification stability and artificial economic cost, combined with the adaptability analysis of the universal primer system and the optimized primer system, the application can determine the applicable scene of the primer selection standard and the eDNA collection method, and then screen the primer system and the eDNA collection method matched with the target sample, and finally carry out eDNA collection and water ecological damage evidence identification. The application can construct an efficient and high-accuracy water ecological damage evidence fixation technology system, realize the rapid collection and high-precision test analysis of the ecological damage evidence of the damaged water body, avoid the damage to the rare and endangered species and the interference to the natural environment, and finally form a standardized and business identification method system with demonstration technology and standard system as the core, so that the application can provide scientific support for water ecological damage identification.

This invention discloses a method for surveying juvenile horseshoe crabs in China based on remote sensing technology and intelligent image recognition. Through a process of rapid comprehensive survey and precise regional survey, a drone equipped with a lightweight YOLO recognition model, RTK positioning, and laser ranging is used to conduct a comprehensive survey of potential habitats, identify juvenile distribution hotspots, and delineate precise survey areas. Then, a full-frame mapping camera is used to conduct ultra-high-resolution drone photogrammetry, combined with an instance segmentation model to complete juvenile contour extraction, coordinate positioning, density statistics, and age determination. This invention overcomes the shortcomings of traditional foot surveys, such as tidal limitations, small coverage area, susceptibility to environmental interference, high missed detection rate, and high personnel risk. It achieves non-contact, high-efficiency, high-precision, and low-disturbance juvenile horseshoe crab surveys, providing a scientific and efficient technical solution for the monitoring of juvenile horseshoe crabs in China and the protection of endangered species.

According to the improved YOLOv11-based Yunnan rare and endangered species monitoring method provided by the invention, the adaptive environment feature enhancement module is embedded, so that noise interference caused by special habitats such as high altitude, strong illumination and foggy conditions in the Yunnan region is effectively overcome, the robustness and stability of feature extraction in a complex environment are remarkably improved, and the accuracy of feature extraction is improved. The problem that in the prior art, the recognition accuracy is sharply reduced in the environment is solved. A traditional feature fusion structure is replaced by a cross-hierarchy feature interaction module, an efficient multi-hierarchy feature circulation interaction mechanism is established, the problem of missing detection of severely shielded targets and minimum population individuals is effectively solved, and the detection rate of the key targets is remarkably increased; by introducing the fine granularity identification module, fine difference characteristics among species are deeply mined, the problem of confusion of related species which are difficult to distinguish in the prior art is successfully solved, and the inter-class distinguishing precision is improved to a practical level.

The application discloses a tissue culture large-scale propagation method of Camellia meiocarpa. The method comprises the following steps: obtaining aseptic seedlings of Camellia meiocarpa, cluster bud proliferation culture, single plantlet culture of adventitious buds, bottle-out root preparation culture and bottle-out root culture. The composition of the cluster bud proliferation culture medium and the plantlet culture medium is optimized, the cluster bud proliferation and the formation of the adventitious buds are promoted, and the proliferation coefficient reaches 8.18. In addition, the bottle-in and bottle-out root culture scheme is combined, so that the rooting rate and the survival rate are significantly improved, and the rooting rate reaches 90%. The tissue culture method has important significance in the protection and population recovery of Camellia meiocarpa, and provides technical support for the protection and sustainable utilization of the endangered species.

The invention provides an operation method of an electronic device of a habitat analysis service. The operation method comprises the following steps: the electronic equipment obtains an image shot by at least one target object and a shooting position of the image; a step in which the electronic device recognizes the target object species on the basis of the image; the electronic equipment identifies whether the identified object species belong to endangered species or not; if the target object species belong to the endangered species, the electronic device sets the target object species as the endangered species; acquiring habitat information of the target species; the electronic equipment obtains habitat and position information of the target object; the electronic device obtains the position of the habitat of the target object and the position of the habitat information; comprising the step of identifying Korean paper.
