北京花园城市建设中竹材应用框架与实现路径OA

Under the policy context of building Beijing a Garden City,the selection of green and low-carbon materials and the innovations in construction methods have become important approaches for improving the quality of urban spaces.As a renewable engineering material,bamboo not only meets the national requirement for timber security but also possesses carbon sequestration potential and strong alignment with landscaping needs,giving it considerable application value in garden city environments.By analyzing relevant policy and planning documents,this study establishes a bamboo application framework in line with the structure of"policy-based planning-spatial scenarios-construction modes"to explore implementation pathways for applying bamboo in park recreation systems and garden-style urban spaces.Focusing on two key system elements—walking trails and facilities,the study proposes a multi-level system for bamboo application in urban building façades,municipal structures and public service facilities,landscape service facilities,and urban furniture.Using a modular all-bamboo triangular house as a case study,the study examines how bamboo-steel composite node design and optimized structural grid spacing can enhance structural safety,construction efficiency,and spatial flexibility.From the perspective of coordination among local standards,planning and design,and engineering technologies,recommendations are proposed for promoting bamboo applications in garden city building.This study provides a reference for the systematic and modularized application of bamboo materials in building Beijing a Garden City and other similar urban contexts in China,and also offers new insights into the broader use of green building materials in urban public spaces.
