居住区冬夏绿视率与绿视因子相关性研究

摘要:
居住区景观影响居民身心健康,而绿视率对评价景观的健康功能以及指导其改造规划都具有重要意义。选取杭州市内23个小区,共607个视点获取全景绿视率。首次使用冬夏绿视率和绿视率年差值的概念,并纳入绿视因子组间差异性比较以探究绿视率影响机制。研究表明:1)高层住宅具有更高水平绿视率;绿化投入影响的房价差异能够衡量居住区绿视率水平;2)游憩视点绿视率水平最高,但道路绿视率更能代表居住区绿视率水平,而以硬质景观为主体的场景则更应注重绿化投入质量和个性化特征;3)杭州市绿视率年差值达到15%,完整植物结构能够提升居住区绿视率水平并增强季相变化。在居住区景观规划设计中应避免绿地破碎,应以10年作为绿视率水平评估单位。详尽解析冬夏绿视率与绿视因子的影响机制,对居住区景观在绿量的规划、应用和评价层面具有指导意义。

Abstract:
Residential area landscape affects the physical and mental health of residents, and the visible green index (VGI) is of great significance to evaluate the health function of the landscape and guide its renovation and planning. This research selects a total of 607 viewpoints from 23 communities in Hangzhou City to capture the panoramic VGI. For the first time, the research uses the seasonal concept of winter, summer and annual difference in VGI, and incorporates the comparison of differences in green vision factors between groups to explore the impact mechanism of VGI. The result shows that: 1) High-rise residential buildings often have a higher level of VGI. The difference in housing prices affected by greening investment can measure the level of VGI in residential areas. 2) The VGI of recreational viewpoints is the highest, but the VGI of roads can better represent the VGI level in residential areas, and the scenes with hard landscape as the core should underline the quality and individual characteristics of greening investment than the green quantity. 3) The annual difference of VGI in Hangzhou reaches 15%. The complete vegetation structure can increase the residential area VGI level and seasonal changes. In the landscape planning and design of the residential areas, it is necessary to avoid fragmentation of the green space, and ten years should be used as the unit of VGI evaluation. The research largely explains the influence mechanism of winter and summer VGI and green vision factors, which has guiding significance for the planning, application and evaluation of green quantity of residential area landscape.
