Wetland conservation is aimed at protecting and preserving areas where water exists at or near the Earth's surface, such as swamps, marshes and bogs. Wetlands cover at least six per cent of the Earth and have become a focal issue for conservation due to the ecosystem services they provide. More than three billion people, around half the world’s population, obtain their basic water needs from inland freshwater wetlands. The same number of people rely on rice as their staple food, a crop grown largely in natural and artificial wetlands. In some parts of the world, such as the Kilombero wetland in Tanzania, almost the entire local population relies on wetland cultivation for their livelihoods.
Image Sensor-Based Method for Detecting Migratory Bird Distribution in Wetland Reserves
PendingCN122313528AFlockSpatiotemporal pattern
This invention relates to the field of migratory bird distribution detection technology, specifically disclosing a method for detecting migratory bird distribution in wetland protected areas based on image sensors, including the following steps: Step S1: Divide the protected area into several sub-regions, set up image acquisition points in each sub-region, acquire migratory bird images in real time, identify the instantaneous number of migratory birds in the images, and simultaneously record the acquisition timestamp and acquisition coordinates; Step S2: Construct a spatiotemporal counting matrix based on the number of migratory birds at different times at each acquisition point, with acquisition coordinates as rows and time as columns, and obtain several basic spatiotemporal patterns and the corresponding linear weights of each pattern through matrix decomposition; Step S3: Based on the change of the linear weights of each basic spatiotemporal pattern over time, identify the migration events of migratory bird flocks between sub-regions, combine the migration events with the spatial distribution preference vectors of each pattern, determine the migratory bird flock gathering areas and migration channels, and generate the final distribution detection results.

Green low-carbon coastal wetland intelligent bird watching method and system
This invention discloses a green, low-carbon, intelligent birdwatching method and system for coastal wetlands, relating to the field of ecological monitoring technology. The method includes: selecting observation points based on environmental data and bird activity information; collecting monitoring data including waterbird images, sounds, and environmental parameters through a multimodal sensor network; processing the monitoring data locally in real time using an edge computing unit, and identifying waterbird species through convolutional neural networks and support vector machines; associating the identification results with the point coordinates to generate observation records and uploading them to the cloud, based on which spatial clustering and behavioral pattern analysis are performed; and finally, providing ecological observation information services to the public. The system includes corresponding deployment, data acquisition, processing, and interaction modules. This invention achieves automated and precise bird monitoring, balancing low-carbon operation with public education, and improves the intelligent level of coastal wetland protection and management.
