Greenways and Their Functions to Eco-Cities

Greenways can be considered as linear open spaces along natural or artificial linear features such as rivers. shorelines, ridgelines, railroads, canals or roads. They are planned, designed, and managed to connect and protect ecological, scenic, recreational, historic, and cultural resources, The archetype of greenways could go back to the landscape axes and boulevards of Europe in the 18^th century and later tire parkways of USA in the late 19^th century . As a means of urban ecological planning, greenway planning is getting more and more important to sustainable development in urban areas and has become a worldwide activity or a movement. This paper reviews the evolution of greenways and identifies it into three distinct stages or “generations ”. introduces a general methodology of greenway planning, and expounds the functions of greenways to ecotitles. At the end. this paper emphasizes that it is significant to enhance the research and implementation of greenway planning in our country in the case that urbanization will be developing qulckly in the next decades.
