通过量化单株行道树的可见绿量将绿视率分析与城市树木种植决策联系起来
可见绿量是城市行道树的重要贡献，已被证明与街道空间质量以及人们的健康和福祉相关。然而，现有方法在量化单棵树木特定场地的可见绿量贡献方面支持有限，从而限制了对特定树木的评估以及对替代种植位置和空间配置的比较。为解决这一研究空白，本研究提出了“基于树木的可见绿量供给”（tVGP）指标，用于量化选定视点下单棵树木的可见绿量贡献，并开发了一种基于3D可视性分析的工具进行计算。该工具包含四个主要步骤：数据准备、树木3D可视性模拟、按树木ID分类视线以及计算tVGP。该工具应用于德国慕尼黑市中心附近的研究区域，以测试计算现有行道树tVGP的可行性并比较假设的种植配置。与全景照片的初步比较显示，模拟结果捕捉到了单棵树木层面可见绿量的相对差异。应用进一步表明，该工具能够识别现有树木的场地特异性变化，区分单棵树木对视点级可见绿量的贡献，并在不同树木数量和空间配置下比较种植替代方案。在评估的情景空间内，种植配置分析显示，随着树木数量的增加，最高tVGP呈非线性增长且收益递减，同时包含相同数量树木的不同配置之间存在显著差异。所提出的工具提供了一个特定场地的框架，将可见绿性分析与单株树木评估以及在一致的空间和模拟设置下对替代行道树种植选项的相对比较联系起来。

However, existing approaches provide limited support for quantifying the site-specific visible greenery contribution of individual trees, thereby constraining the evaluation of specific trees and the comparison of alternative planting locations and spatial configurations. To address this research gap, this study proposes Tree-based Visible Greenery Provision (tVGP), a metric that quantifies the visible greenery contribution of individual trees across selected viewpoints, and develops a 3D visibility analysis-based tool for its calculation. The tool comprises four main steps: data preparation, simulation of the 3D visibility of trees, classification of sightlines by tree ID, and calculation of tVGP. It was applied to a study area near the center of Munich, Germany, to test the feasibility of calculating tVGP for existing street trees and compare hypothetical planting configurations. A preliminary comparison with panoramic photographs showed that the simulated results captured relative differences in visible greenery at the individual-tree level. The applications further demonstrated that the tool can identify site-specific variation among existing trees, distinguish the contributions of individual trees to viewpoint-level visible greenery, and compare planting alternatives under different tree numbers and spatial configurations. Within the evaluated scenario space, the analysis of planting configurations showed nonlinear increases and diminishing gains in the highest tVGP as tree number increased, together with substantial variation among configurations containing the same number of trees. The proposed tool provides a site-specific framework for linking visible greenery analysis with individual-tree assessment and the relative comparison of alternative street-tree planting options under consistent spatial and simulation settings.
所提出的基于tVGP指标和3D可视性分析的工具能够有效量化单棵树木的可见绿量贡献，识别场地特异性变化，并支持在不同树木数量和空间配置下对替代种植方案进行比较，为连接可见绿性分析与个体树木评估及种植决策提供了框架。
