基于城市生物多样性提升的杨凌树木园景观规划设计研究

生物多样性营造是城市绿地建设的重要议题，传统的植物园注重生物多样性而景观功能缺失，公园以景观功能为主但生物多样性匮乏。因此，如何协调生物多样性和景观功能之间的矛盾是城市植物园建设面临的难题之一。基于此，本研究以陕西关中植物区系为基础，通过分区规划、游览路径和植物景观规划、生物多样性解说系统充分展示陕西关中地区的植物区系和生物多样性，同时营造丰富的生境多样性、植物多样性、群落多样性和景观多样性，通过实践协调了我国树木园面临生物多样性展示与植物景观营造之间的矛盾，为城市树木园的营建提供了理论依据和实践指导。

Landscape Planning and Design of Yangling Arboretum Based on the Promotion of Urban Biodiversity

The biological diversity construction is an important issue for the construction of urban green spaces.In traditional botanical garden,attention was paid to biodiversity,leading to the lack of landscape function.While in modern park construction,priority is given to landscape function,resulting in the lack of biodiversity.Therefore,how to coordinate the biodiversity and landscape functions is one of the challenges faced by the city botanical garden construction.The biodiversity and landscape diversity is well balanced in the construction of "Yangling Arboretum",in which the flora collected was mainly from central Shaanxi Plain (Guangzhong).The biodiversity was reflected by its zoning plan,the tour path,and the plan of plantscape.At the same time,the arboretum created a rich habitat diversity,plant diversity,community diversity and landscape diversity.The arboretum coordinated the contradiction between the planscape construction and displayed of the biological diversity about the arboretum in China through practicing,and provided a theoretical basis and practical guidance for the construction of urban arboretum.
