environment. Areas are selected because of their utility and their position related to other areas. If some stakeholders disagree with a selection, the planner can propose some alternative areas, possibly with the same value, or an alternative area can be prepared to be as useful as the previous one. Thus, areas and their spatial formation are exchangeable and flexible because their value is abstract and not site-specific. These are excellent requirements for implementing green infrastructure in argumentative planning processes. The planning goals are the preservation, construction, and connection of habitats and/or urban green spaces. Because a network is a flexible form and the knots of a net do not have to be on specific places (but in specific relationships), it is possible to find alternative spatial compositions if, e.g., some selected areas are not available. The network is therefore a practical geometric model to create a spatial correlation. Before this background, the concept of green infrastructure and green infrastructure planning provides a pragmatic working method to preserve and develop green spaces well grounded on their functions for human well-being.
Aesthetics, however, is the weak point of the method. With a long tradition in 19th-century urban park planning and nature preservation, the concept has incorporated the traditional pattern of landscape aesthetics in its performance. As this aesthetic pattern is functionalized and naturalized in the method of green infrastructure planning, it is quite difficult for new aesthetic patterns to emerge. Aesthetic value is not necessary to support the establishment of green infrastructure; what counts are the ecosystem services they can provide.
