Translation from Principles of Natural Science and Technology to Design Language of Landscape Architecture: Study on Ecological Design Techniques of River Reach Scale

There is a gap between theory and practice in the study of river ecological restoration. Landscape architecture science is the best way to integrate theories of various disciplines and eventually transform them into practice. The core of this study is to transform the theory of river ecological restoration into landscape design language, i. e. ecological design techniques, mainly with the T-P-C (Theory-Pattern-Case) method. Firstly, it analyzes the spatial elements of rivers, and then translates a set of design rules according to relevant principles of natural science and technology. Finally, along with ecological problems of rivers, it extracts 15 ecological design techniques under river reach scale, such as “flood land bending reconstruction”, “ecological riverbed”, “ecological dam reconstruction”, to provide designers with a set of ecological, spatial, inductive, multi-scale and typological design tools.
