La dilution : note méthodologique pour l'analyse de l'étalement urbain

Abstract

The simplest definition refers to diluted areas as areas with a lower built-up content. Dilution is characterised by a gradation of developed sites as distance from the centre increases. The logistical model appears to summarise this continuum well. It is useful if we are trying to work out the difference between two periods. We can thus highlight logistics specific to the growth of built-up areas. The dynamic model makes it possible to project trends to 2010, 2020 or 2030. At the same time, we can forecast dilution patterns through difference, which leads us to the conclusion that the diluted area is likely to be extended and the warming point move farther away.
