摘要：The loss of free and green spaces and their associated advantages for the urban population is a major
threat for urban sustainability. The idea of planting roofs in order for them to act as natural filters
within the urban tissue has been increasingly recognized as a technology that has the potential to
diminish drastically the environmental problems of urban centers. In many countries, special laws
are introduced which provide citizens with incentives or even involve an obligation to build green
roofs. The objective of the research presented herein is to investigate and record the impact of the
use of green roofs for the development of urban policies which aim at improving the quality of urban
environment, using a combination of Geographical Information Systems (GIS) technology and
specialized software. The developed methodological framework is applied to a real-world case study
of a medium – sized Greek city. The use of a comprehensive GIS environment not only contributes to
improving the quality of research but also offers the possibility of continuous updated information
and monitoring of the factors that influence the development of green roof policies.
