Abstract: [Purposes] The real-scene 3D China has been initially established.This paper aims to deeply analyze its application development status，further explore its application value，and fully release the potential of data. [Methods] Based on the data of 304 real-scene 3D application cases released by the Ministry of Natural Resources，provincial and municipal information release platforms from 2024 to 2025，it systematically analyzes the scene distribution，regional differences，participating entities and evolution patterns of real-scene 3D applications in China by using spatial statistical analysis，comprehensive comparative analysis and other methods. [Findings] The results show that assisting government decision-making and supporting natural resource management are the core application scenarios，accounting for over 60%，which have contributed to the rapid growth of the digital economy.The application leading trend in the eastern region is remarkable，while the characteristic applications in the central and western regions are accelerating their rise.Public institutions have become the core implementing entities，and a multi-party collaborative model has initially taken shape. [Conclusions] In the future，it is necessary to promote the continuous deepening and expansion of real-scene 3D applications through regional collaboration，mechanism innovation，and technological integration，so as to better serve the high-quality development of China's economy and society．
