Abstract: The construction of ecological network or other continuous habitat is essential for urban eco-system; however, to quantify the heterogeneous functional connectivity for eco-network is academically attractive and challenging. The dynamic lines of space syntax, tenable to simulate perception and navigation flows in network-configured human settlements, is introduced to inspire idea and approach to modeling connectivity in eco-network, while the classical graphic notions and variables are assumed functional to new relationship between other species and eco-network. After mapping continuous functional components among land layout into free space and then into dynamic lines that influence bio-flows, the paper conducts an exploration on functional connectivity of Singapore's green network. Conclusions involves the distribution heterogeneity of basic variables, Connectivity, Control, Mean Depth and Integration, demonstrating each meaning for functional connectivity in the network, with a step-wise Integration further comparing the connectivity patterns under different behavioral ranges. Moreover, a scale robustness determined via linear regression between Integration and Connectivity reveals network functionality as behavioral scale varying. The analogical modeling of space syntax raised in this paper is adaptive and instructive, particularly if original essential traits remain valid between the substituted species and space, because several principles and characteristics of conventional connectivity models can be logically inherited, while the graphic notions of dynamic line shares unique advantages.
