With the support of ArcGIS, the vector and raster data of Guangzhou forest were handled by operation of spatial methods, finally, a raster based spatial analysis software Fragstats3.3, the forest landscape patterns of Guangzhou were analyzed in this paper. The mostly distributed forest landscape type is broad-leaved mixed forests, which occupied 40.83% of the total forest area in Guangzhou. In patch class level, the pattern of forest landscape varied largely among different districts of Guangzhou, and the urbanization greatly influenced the fragmentation of forest landscapes. The landscape diversity did not vary largely, and the diversity of the forest landscape in Guangzhou is relatively high, but the richness density was very low, reflecting the area of forest patches are relatively large in Guangzhou. In the 10 studied sub- districts of Guangzhou, Conghua and Zengcheng had the highest forest coverage rate, 70.73% and 53.45 %, respectively, followed by Huadu District (37.79%). In Huangpu District, Luogang District, Baiyun District and Panyu District, the forest coverage rate was less than 20%. There is no distribution of forest landscape in the old downtown of Guangzhou (Haizhu, Liwan and Yuexiu), Nansha also distributed scarcely forest landscape. At the landscape level, landscape diversity index and evenness index did not differ greatly among 10 sub-districts, indicating forest landscapes are highly evenly distributed in Guangzhou.
