| 摘 要： | 为了解城市绿道植物空间绿量可视性特征，通过构建绿视率计量方法，以广东省立绿道1号线为例进行调查分析，探索了基于绿视率的城市绿道空间绿量可视性特征。结果表明:①省立绿道1号线沿线4个区域总的绿视率均值为31.06%，其中天河区（38.19%）＞海珠区（35.97%）＞越秀区（26.76%）＞荔湾区（26.67%）。②天河区绿道与荔湾区、越秀区绿道绿视率存在显著差异（P＜0.05），表明天河区绿道空间绿量可视性优于荔湾区和越秀区；虽然海珠区绿道绿视率较荔湾区和越秀区高，但通过方差分析多重比较来看，3个区的绿道绿视率没无显著差异（P＞0.05），表明荔湾区、越秀区、海珠区绿道的空间绿量可视性较相似。③越秀区和天河区绿道绿视率较为集中地分布在24%～40%区间，说明越秀区和天河区各自区域绿道内部的绿视率数值较为稳定，其空间绿量可视性效果差异不大，给人感觉一种持续、稳定的绿色空间；而荔湾区和海珠区绿道绿视率的分散在10%~50%，说明荔湾区和海珠区各自区域绿道内部的绿视率数值不稳定，其空间绿量可视性效果差异较大，给人一种间断、具有冲击力的绿色空间。基于绿视率的空间绿量可视性可用于评价城市森林建设的视觉效果。图4表4参21

| Abstract: | To understand the spatial visibility of green areas of urban greenway in urban greenway, the green-appearance percent was used to determine and analyze green areas of greenway line 1. Through the photos took by Nikon D800, the green-appearance percent was calculated with Photoshop. Results indicated that 1） the average total green-appearance percent of greenway of four Guangzhou Districts was 31.9% with Tianhe （38.2%） ＞ Yuexiu （36.0%） ＞ Haizhu （26.8%） ＞ Liwan （26.7%）. 2） Using one-way ANOVA, the green-appearance percent of greenway in Tianhe District was significantly greater （P ＜ 0.05） than Yuexiu and Liwan Districts. 3） The green-appearance percent of greenway in Yuexiu and Tianhe Districts was between 24.0% and 40.0%; Whereas, in Liwan and Haizhu Districts green areas were 10.0% to 50.0%. Thus, Yuexiu and Tianhe Districts were relatively stable providing a sustained, stable green space; but Liwan and Haizhu Districts were unstable with a discontinuous, sporadic green space. The green-appearance percent cloud be used to ecaluate the visual impact of various planning and management on urban forests.［Ch, 4 fig. 4 tab. 21 ref.］ |
