Greenways play an important role in building a continuous ecological open space system in an urban agglomeration. Based on the regional greenways in the Pearl River Delta urban agglomeration, topological network analysis and social network analysis were used to assess the connectivity and distribution pattern of ecological recreation space-regional greenway network. The results show that: 1) The α, β, and γ indices are 0, 0.386, and 0.129 respectively, indicating a low-circuitry and low-connectivity topological structure of the network. 2) The network is clustered, and the degree of connectivity of the cohesive subgroups at the edge is higher than that of the central region. 3) The degree of connectivity between the cohesive subgroups in the eastern and northern regions is greater than that of the cohesive subgroups in the western region, and the connectivity between the western subgroups and eastern subgroups is low, suggesting that the network is fragmented in the east-west direction. 4) The distribution pattern of the connectivity is formed under the influences of the greenway development policy and layout, the greenway construction mechanism, the agglomeration pattern of ecological recreation spaces, geographical barriers, and spatial proximity. Several pathways were proposed to construct an ecological recreation space-greenway network with higher connectivity, for providing some references for the planning and development of China's urban agglomerations.
