Research On Application Of Salvaged Materials And Regenerative Materials In The Context Of Resource-efficient Landscape

The adjustment of industrial structure and rapid urbanization brought about the accumulation of construction waste and industrial solid waste, from the perspective of the nature circulation of material and energy, these salvaged materials are actually resources which were in wrong time and wrong place. Material is the material basis for the landscape construction, nowadays, resources being increasingly scarce and environment being deteriorating, selection of landscape materials is still given priority to natural resources, construction of landscape architecture relies on obtaining natural resources massively and fleetly all the same, material-saving measures based on the current situation of landscape architecture construction in China are in urgent need, making use of salvaged materials and regenerative materials are able to broaden methods of application of salvaged materials, change the situation that traditional construction mode depend on natural resources, of which is the research purpose of this paper.Circular economy is developed mightily in our country, resource-conservation and environment-profitable society is being advocated, the putting forward of resource-efficient landscape conforms to the theme of the time and points out the direction for the development of landscape architecture. Requirements of resource-efficient landscape are maximizing the saving of resources and reducing energy consumption under the premise of not to reduce the construction scale and construction investment and construction quality. The present situation of the application of landscape materials is carried on the induction, strategy of material application is presented combined with the connotation of resource-efficient landscape in this paper.Phenomenology as the research method is introduced into the research of this paper, speculations of authenticity and nature of material is the starting point of research, the tectonics logic is the core content of the research of salvaged materials and regenerative materials, which broaden the theoretical system of landscape materials and research methods and provide a theoretical support for the research of this paper.The present situation of the application of salvaged materials and regenerative materials is systemized in this paper, first of all, the application of salvaged materials and regenerative materials in municipal road engineering and construction engineering is studied, the materials and engineering technology which could be applied to landscape architecture are summarized. Through the research of construction thought of "low material with high technique" in Chinese classical garden construction with salvaged materials and construction technology of "walls of discarded tiles" and "walls of discarded bricks and stones", this paper summarized the history of the application of salvaged materials.This paper summarizes the construction waste, industrial solid waste and regenerative materials which could be applied to the landscape architecture, the approach and tectonics logic of salvaged materials and regenerative materials are studied, which provide a reference for landscape design and engineering construction, which is also the practical significance of this paper.This paper sums up the conservation value, artistic value and optimization value of salvaged materials and regenerative materials in the application, studied the realization methods of the value in combination with the design practice case which the author was participate in, evaluated the application value of salvaged materials and regenerative materials by making use of the AHP method, which lays the foundation for the establishment of the evaluation system for materials in landscape architecture.This paper has presented an implenmentation frameworks of landscape construction, basing on the use of salvaged materials and regenerative materials as builidng materials. The framewok adds a management system of salvage materials and a landscape material evaluation program based on LCA to the landscape construction procedure, which on one hand applies the need of using salvaged materials and regenerative materials, and on the other hand closely integrated with the actual situation of China’s landscape architecture construction. In addition, the paper has proposed principles for landscape design and strategies for constructional organization focused on the unconventionality of making use of salvaged materials and regenerative materials as landscape materials. The establishment of implenmentation frameworks could form the driving force of applying salvaged materials and regenerative materials to landscape architecture on levels of indusrty policy, information management, planning and design, construction implementation.
