Floating Solar Park Impacts Urban Land Surface Temperature Distribution Pattern

In recent years, the global photovoltaic industry has developed rapidly. It is significant for evaluating the impact of large-scale solar parks on the environment for the sustainable development of the photovoltaic industry. At present, researchers have paid attention to changes in
 the local thermal environment caused by solar parks. As a new type of solar park, the influence of floating solar parks on urban land surface temperature distribution patterns is still unclear. In this article, we (1) take the floating solar parks in Huainan City, China, as the study area;
 (2) calculate the land surface temperature (LST) of the study area and its adjacent areas by using Landsat 8 remote sensing data and the radiation transfer equation method; and (3) judge the influence of solar parks on the distribution pattern of LST. On this basis, we analyzed the influence
 range and seasonal differences of floating solar parks on LST. Our results revealed that, first, the floating solar park has a warming effect in the summer and winter, and the warming area is concentrated mainly within 200 m of the photovoltaic panels' coverage area. Second, during the construction
 phase and after the completion of the floating solar parks, the average monthly LST of the solar panels is generally higher than the water, and the average annual temperature increase in the above two stages is 3.26°C and 4.50°C, respectively. The change of floating solar parks on
 urban LST distribution patterns may impact the local ecosystem. In the future, it is necessary to consider the impact of floating solar parks on local LST during the construction of floating solar parks.
