<p>With the acceleration of urbanization, the protection and reuse of industrial heritage are increasingly valued. This article aims to explore the application of virtual reality technology based on environmental thermal modeling in industrial heritage landscape design, in order to enhance the scientific and practical nature of landscape design. The study reviewed the work in related fields and adopted a three-dimensional environmental thermal energy simulation process, combined with a dynamic temperature management prediction model and real-time temperature tracking testing, to construct a comprehensive thermal management framework. Through virtual reality technology, this article has developed a simulation system for industrial heritage landscape design. The overall framework of the system includes the landscape design process and irregular landscape grid deformation algorithm, ensuring high accuracy and flexibility of the 3D model. The results indicate that design optimization strategies based on thermal energy simulation can significantly improve the environmental adaptability and tourist experience of industrial heritage landscapes. By optimizing the scene elements and implementing update strategies, the design scheme not only enhances the historical value of the heritage landscape, but also improves its environmental comfort.</p>
