基于绿视率的城市绿道空间绿量可视性特征
Spatial visibility of green areas of urban greenway using the green appearance percentage
摘要
Abstract
To understand the spatial visibility of green ar eas 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 av-erage 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.关键词
