我们探索了谷歌街景（GSV）作为一个街道级的城市绿化评估工具。街道绿化长期以来在城市景观的视觉质量中发挥着关键作用。这种生活景观元素的视觉影响的质量可以而且应该与GSV信息进行评估，评估的街道级绿化信息可以被纳入城市景观规划和管理。然而，关于城市绿化评估的街道水平视图的信息很少或根本不存在。因此，规划者和管理者有效和高效地规划和管理城市景观的能力是有限的。GSV是一种可以提供街道水平的城市景观和绿化的剖面视图的工具，但在文献中似乎没有关于GSV用于城市规划的研究。我们修改了现有的绿色景观指数（GVI）的公式，并进行了案例研究评估街道绿化使用GSV图像在该地区的东村，曼哈顿区，纽约市。我们发现，GSV是非常适合评估街道绿化。我们进一步建议，修改后的GVI可能是一个相对客观的衡量街头绿化，GSV结合GVI可能是非常适合在指导城市景观规划和管理。(C)2015 Elsevier GmbH.

We explored Google Street View (GSV) as a street-level, urban greenery assessment tool. Street-level greenery has long played a critical role in the visual quality of urban landscapes. This living landscape element can and should be assessed for the quality of visual impact with the GSV information, and the assessed street-level greenery information could be incorporated into urban landscape planning and management. Information on street-level views of urban greenery assessment, however, is rare or nonexistent. Planners and managers' ability to plan and manage urban landscapes effectively and efficiently is, therefore, limited. GSV is one tool that might provide street-level, profile views of urban landscape and greenery, yet no research on GSV for urban planning seems available in literature. We modified an existing Green View Index (GVI) formula and conducted a case study assessment of street greenery using GSV images in the area of East Village, Manhattan District, New York City. We found that GSV to be well suited for assessing street-level greenery. We suggest further that the modified GVI may be a relatively objective measurement of street-level greenery, and that GSV in combination with GVI may be well suited in guiding urban landscape planning and management.
