Overview

Randomized trial quantifies relationships between green view index and vegetation in Nanjing, suggesting urban planning improvements.

Key Points

  • This study aims to analyze the relationship between street-visible greenery and overhead vegetation greenness in Nanjing.
  • Utilized 118,830 panoramic street-view images to calculate the Green View Index (GVI).
  • Employed NDVI-based remote sensing and semantic segmentation for vegetation analysis.
  • Conducted spatial distribution analysis considering seasonal variations and vegetation compositions.
  • Citywide mean GVI was 0.273 (SD 0.208), showing significant spatial heterogeneity.
  • Moderate positive correlation observed between GVI and NDVI, with seasonal variability in correlation strength.
  • Higher GVI values found in ecological zones, while traffic-priority roads showed lower greenery levels.
