Abstract:At present, the world is facing major changes in new energy technologies, and the development of clean and low-carbon energy has become a new trend. As a clean energy source and a huge potential for development, dry hot rock has been paid more attention from all walks of life. For the time being, the research on dry hot rock is still in its infancy, and there is great difficulty in determining the target area. Through Landsat8 winter remote sensing image data, Envi5.3 software is used to perform 754-band false color synthesis, and the line ring structure is manually interpreted. By using the atmospheric correction method, combining with local temperature, eliminating the influence of urban buildings, inverting the surface temperature, and using remote sensing images, hydroxyl alteration information has been extracted, and the interpretation results have been classified. Regarding 30 municipal administrative districts as the basic evaluation unit in the study area, by using collected geothermal data of Shandong province, the aeromagnetic gravity anomaly data, combining with the expert scoring method and the analytic hierarchy process, using comprehensive evaluation formula, evaluation unit has been scored. The higher score is the suitable area for dry hot rock development. The suitable area is Rizhao city. The more suitable areas are Zhaoyuan city, Qixia city, Zhucheng city, Wulian city, Weinan city and Jimo city, other urban areas are less suitable. This research will play an important role in improving local investment and stimulating local resource utilization, effectively improving the energy supply structure in Ludong and promoting economic and social sustainable development with inestimable social benefits.
