With the rapid development of information technology, application of digital and fabrication technology in design develops from only focusing on the digital concept design to paying more attention to the "integrity of the process from virtual design to building entity". Based on the result of Tongji University digital fabrication technology research, this study explores the application of digital design and fabrication technology such as Autogenic Forms technology, Human-computer Interaction technology, Analysis of Environmental Performance technology, Computer Numerical Control Technology (CNC) and Traditional Materials Multi-dimensionality Expression technology in the practice of Landscape Architecture.
