Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of flood storage and detention area supervision, and in particular to a flood storage and detention area supervision system and method based on remote sensing images. Background Art
[0002] Flood storage and detention areas have the dual functions of regional flood control and the survival and development of residents in the area. They have played an important role in the prevention of flood disasters in the basin and ensured the safety of important cities and important flood control areas in the middle and lower reaches of the river. In the early days of the establishment of flood storage and detention areas, most of the areas were sparsely populated, and the losses caused by flood storage were relatively small, so the flood storage and detention areas were put into use relatively smoothly. However, with the development of the economy and society, the population has continued to increase, natural lakes and depressions have gradually been occupied, and the degree of land development and utilization in flood storage and detention areas has continued to increase, resulting in the contradiction between flood storage in flood storage and detention areas and ensuring the safety of life and property of residents in the area and developing the economy. It has become increasingly difficult to make decisions on the use of flood storage and detention areas. Therefore, it is particularly important to strengthen the supervision capacity of flood storage and detention areas.
[0003] At present, the supervision of flood storage and detention areas mainly includes: approval and supervision of non-flood control construction projects, water situation monitoring during flood season, and post-disaster compensation. In flood storage and detention areas, the approval process of non-flood control construction projects usually involves multiple departments and links, including the construction unit submitting a flood assessment application, the water administration department conducting a project review, the local government's approval, and the final approval of the river basin committee. Although this process ensures that the opinions and standards of all parties are taken into consideration, its cumbersomeness and manual operation often lead to a long approval time, delayed information feedback, and difficulty in achieving effective monitoring of the project implementation process. During the flood season, water situation monitoring mainly relies on the monitoring data of hydrological stations. Although hydrological stations provide basic water level and flow data, their monitoring frequency and spatial coverage are limited, making it difficult to reflect the dynamic changes of water conditions in flood storage and detention areas in real time. In addition, the data update of hydrological stations usually relies on regular manual inspections, which cannot meet the needs of rapid response under sudden weather events.
[0004] Therefore, there is an urgent need for a flood storage and detention area supervision system and method based on remote sensing images to build an integrated supervision platform, realize intelligent management and emergency response, significantly improve the supervision efficiency and response capacity of flood storage and detention areas, and provide strong support for flood prevention and regional sustainable development. Summary of the invention
[0005] In order to solve the above technical problems, the present invention provides a flood storage and detention area supervision system and method based on remote sensing images, which can realize intelligent management and emergency response, improve information sharing, and significantly enhance the supervision efficiency and response capability of flood storage and detention areas.
