Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of soil and water loss monitoring, in particular to a water conservancy soil and water loss intelligent monitoring device based on remote sensing technology. Background Art
[0002] Soil and water loss monitoring is crucial in the fields of water conservancy projects and ecological and environmental protection. Soil and water loss not only leads to a decline in soil fertility and land degradation, but can also trigger a series of ecological and environmental problems, including river siltation and flooding. Traditional soil and water loss monitoring methods rely primarily on field surveys and manual sampling, which suffer from limited monitoring coverage, poor timeliness, and high costs.
[0003] With the development of remote sensing technology, remote sensing images can be used to obtain surface information over a large area, providing a new means for soil and water loss monitoring.
[0004] In the existing technology, soil erosion is estimated only based on vegetation cover, rainfall, and topographic factors, without considering the impact of dynamic changes in overland flow velocity on soil erosion, making the monitoring results unable to accurately reflect the actual soil and water loss situation.
[0005] In some models, the overland flow velocity is regarded as a fixed value, without considering that changes in vegetation cover will lead to changes in overland flow velocity, thereby affecting the calculation results of soil erosion.
[0006] In addition, most existing soil and water loss monitoring systems are static and lack a mechanism for dynamic adjustment based on real-time monitoring data. Once the initial monitoring parameters and models are set, it is difficult to make timely adjustments based on changes in actual conditions, and they are unable to adapt to the complex and changeable soil and water loss process.
[0007] Therefore, those skilled in the art have provided an intelligent water conservancy and soil erosion monitoring device based on remote sensing technology to solve the problems raised in the above background technology. Summary of the Invention
