In reeent years land utilization in urban areas and their periphery is inereasing. This leads to a deerease in landseape diversity and an inerease in the disintegration of natural areas. Landseape planners and landseape eeologists agree that the establishment of an eeologieal framework (infrastrueture) is essential to ensure sustainable lanseapes. Sueeessful greenway planning examples for to be able sol ve this problem, probable have seen in west eountries. The greenways strategy is eonsistent with the eoneept of sustainable development, in that it is based on an assumed eomplementarity between nature proteetion and eeonomie development. Greenway systems either proteet to planned areas natural and eultural resourees or provide to sustain these resourees values. The aim of this artiele is to explain greenway eoneept and, emphasizes to importanee for nature proteetion and sustainability. In this way; the aims and functions of greenways were presented at introduction. And then nature proteetion funetions, whieh is in greenways funetion, were elarifyed and eorridor eoneept was investigated. Finally, sustainable development, sustainable urbans that is a part of sustaianable development and the eontribution of greenways were argued.
