In the face of China's rich cultural resources, this paper aims to use Citespace tool to measure and analyze the field of cultural heritage digitization under the background of cultural science and technology integration. It focuses on the digital protection of material and cultural heritage, the digital protection of Intangible Cultural Heritage, and the development of digital culture under the integration of culture and technology on the basis of the remarkable achievements in digital reconstruction technology, cultural big data storage and digital innovation tool platform. Also the design participation goal in the development of digital culture is deeply discussed, such as using immersive technology to enhance the accessibility of digital culture, carrying out cooperation to promote the reuse of digital culture, and mobilizing public participation to promote the reflection of digital culture. In order to have a clearer understanding of the specific areas in which design participates in Digital Cultural Innovation, this paper conducts further research to process and make use of the existing cultural data from the angles of designing and applying digital technology, to improve the user-oriented cultural experience, and promote the development of cultural ecology of digital culture by using bibliometric method. It improves the user-oriented cultural experience, and balances the dual-track innovation development of digital culture between industry and public through multi-dimensional cultural value assessment, thus further promoting the innovation of digital culture and providing new space and pattern for Chinese culture going out.
