Detailed Description of the Invention

[0020] The wetland ecosystem is one of the important natural resources on the earth, with rich biodiversity and unique ecological functions. Aquatic insects, as an important part of the wetland ecosystem, the changes in their species and quantity can reflect the health status of the wetland ecosystem. Therefore, the investigation and research on wetland aquatic insects are of great significance. Traditional investigation methods for aquatic insects usually rely on manual sampling, which is not only time-consuming and laborious, but also easily affected by human factors, resulting in insufficient accuracy and representativeness of the sampling results. In recent years, with the development of science and technology, new wetland aquatic insect investigation and sampling devices have emerged, significantly improving the efficiency and accuracy of sampling.

[0021] Traditional wetland aquatic insect survey methods mainly include netting, trapping, hand netting, etc. Although these methods are simple and easy to implement, there are many problems in practical applications. First, manual sampling is greatly affected by factors such as weather and terrain, resulting in low sampling efficiency. Second, human errors are easily introduced during the manual sampling process, leading to insufficient accuracy and representativeness of the sampling results. In addition, traditional methods are difficult to sample at different water layers and cannot comprehensively reflect the distribution of wetland aquatic insects. Traditional aquatic insect survey methods mainly rely on manual sampling and laboratory analysis, with problems such as low sampling efficiency, high labor intensity, and high data errors.

[0022] Traditional aquatic insect survey methods mainly include manual sampling and laboratory analysis. The specific steps are as follows: 1. Manual sampling: Researchers usually use tools such as nets and spoons to manually collect aquatic insects in the water body. This method is simple to operate but has low efficiency and is easily affected by human factors, resulting in uneven sampling. 2. Laboratory analysis: The sampled specimens need to be taken back to the laboratory for classification and identification. Laboratory analysis usually takes a long time and requires high professional knowledge of researchers. In addition, the specimens may deteriorate during transportation, affecting the accuracy of the analysis results.

[0023] With the development of technology, various advanced aquatic insect survey sampling equipment and devices have emerged, greatly improving the efficiency and accuracy of sampling. Therefore, the development of new wetland aquatic insect survey sampling equipment has become an urgent need.

In addition, by integrating multiple sensors and data acquisition modules, the equipment can collect more environmental parameters such as water quality, temperature, light, etc. These data are comprehensively analyzed together with the sampling data, providing a more comprehensive and scientific basis for the protection and management of wetland ecosystems.

[0030] In a river ecosystem in southern China, researchers used a multi-functional wetland aquatic insect sampling device to conduct investigations on aquatic insects. This device can simultaneously sample at different water layers and automatically identify and classify the sampled insect species through an intelligent recognition system. The research results show that this device is superior to traditional manual sampling methods in terms of sampling efficiency and accuracy. The specific performance is as follows: 1.

This enables researchers to obtain sampling data in a timely manner for data analysis and decision support. In addition, by integrating multiple sensors and data acquisition modules, the device can collect more environmental parameters, such as water quality, temperature, and light. These data are comprehensively analyzed together with the sampling data, providing a more comprehensive and scientific basis for the protection and management of the river ecosystem.
