When the populations in the cities are increased, their suburbs are exposed to the expansion of the urban space, which leads to the advancement of the cities in their vicinities. One way to prevent extensive growth of the cities is creation of green belts around large cities. This approach has many environmental values, making the nature and extensive perspectives available for urban communities. The city of Frankfurt is one of the successful examples in utilizing green belts. This paper deals with analysis of green belts, especially the Frankfurt green belt. Due to its geographical situation, this city has valuable natural resources in its surroundings that urban managers have preserved them intellectually, preventing irregular expansion of the city. A multi-functional space for the green belt in a natural area was considered for the citizens in the plan by Bernard Lassus. In addition to promoting the region ecological levels, this space has transformed it into a place for entertainment and education for the urban community. For the unification of the existing irregular places in the city suburbs, Lassus made necessary actions in this plan to establish unified generalities comprised of different elements, by acknowledging the differences of the places and also their organization. One of the most important achievements of this plan is the distinction of landscapes and preserving various living species, agricultural and jungle lands around the city and creating intermediate social activities for supporting an active urban community.
