In response to the increasing demand for electricity, existing power plants have gradually moved to reconstruction or expansion. Due to the current mainstream power generation mode, whether using coal-fired or nuclear power generator sets, there is a problem that the generator set needs to be cooled. Therefore, the power plants are mostly located in the coastal areas where a large number of water sources can be easily obtained. In order to avoid the direct impact of heated water discharge on the ecological environment, understanding the influence of warm water drainage on the nearby sea area and finding out its diffusion mechanism is an important issue in the marine ecological environment. The research on field surveying of sea temperature change is more based on the Eulerian type. The instruments used for fixed-point observation are costly and difficult to maintain. The cost of observation work is expensive, and only a single point of data can be obtained, and it`s hardly possible to observe comprehensively on the temperature distribution of the sea area . This study explores the application of thermal infrared temperature imaging technology, in conjunction with UAV in the sea area around the heated water discharge of Ho-Ping sea area for UAV thermal infrared images photography operations. According to the results, it takes only 15 minutes for a single operation time to make multiple observations in one tidal period, and analyze the difference between the rising and falling tides for temperature and the diffusion of near-shore heated water discharge to comprehend the sea surface temperature distribution.
