Constructing green space ecological network to link the dispersed important ecological patches is an effective way to use limited ecological land for protection of regional ecological security. The biodiversity-rich habitat patches with the minimum cumulative resistance model was chosen to simulate the potential ecological corridors, establish recommended ecological network, and evaluate their connectivity and land use structure. The results show that the ecological network established in this project is very similar to the structure of the ring network, and can meet the actual circs. The forest park group located in the border region of Baiyun, Tianhe and Huangpu, as the key network node, is an important hub for exchanging landscape material among the north, central, and south of the study area. The northern part of dense forest in Guangzhou has a larger area of ecological patches and smaller resistance of ecological corridor. Due to intense development and construction, the central and southern Guangzhou have smaller areas of ecological patches that are scattered and larger ecological corridor resistance, with the appropriate width of the corridor less than 100 m.
