摘要：[Objective] The aim was to construct a virtuous eco-system covering multi-populations, multi-layers and multi-products and to explore timber production of physical and non-physical products, in order to extend products operated in forestry engineering and seek a novel model for forestry engineering. [Method] A three-dimensional operation project was designed based on forestry lands in Bagua Zhou in Nanjing City. [Result] In the project, timber products, by-products in forest and relaxing products supplimented and supported each other, and a virtuous circle has been achieved. [Conclusion] The novel model makes simultaneous relaxing and working possible, which creat vaule together.
