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.］
