In recent years, urban greenway network planning began in the eastern part of our country where the economy are more developed, presenting a nationwide spread trend. Greenway network construction will become a trend of Chinese green space planning.

Though 3-5 typical cases study of the greenway construction being widely recognized, the paper try to sum up greenway network planning characteristics, construction ways and planning principles in each level. Furthermore, the last part of this paper attempts to summarize the greenway network planning procedures and discusses how to engage with our coutry's urban planning system.
