建成环境道路绿带生境特征研究

绿地自身及其所处空间的形态特征对于植物生境的塑造具有重要的影响。以建成环境道路绿带为研究对象,通过数字化模拟与实地采样调查,分析和总结包括光照因子、局地风环境、土壤水因子、土壤理化属性在内的主要生境因子特征及其与道路绿带空间因素之间的关系。研究发现:光照因子、局地风环境与街谷形态、绿带位置关联密切;土壤水因子、pH值与绿带宽度存在显著相关性。生境分析为绿带植物营造提供科学依据,指向种植设计与场地设计之间的双向适应。

Research on Characteristics of Road Greenbelt Habitat in Built Environment

The spatial characteristics of both green space itself and its surroundings have an important effect on the shaping of plant habitats. Taking road greenbelts in built environment as the research object, and applying digital simulation and filed sampling survey, the study analyzed the characteristics of main habitat factors, including illumination, local wind, soil moisture, soil physical and chemical properties, and discussed their relationship with the road greenbelt spatial factors. It is found that the illumination factor and local wind condition are closely related to the street canyon shape and greenbelt locations on the roads; and the soil moisture and its pH value are significantly correlated with the widths of greenbelts. The habitat research provides scientific basis for greenbelt plant construction, leading to a bidirectional adaptation between planting design and site design.
