绿道绿道(Greenway)是指那些未经政府开发的,出于休闲或环保目的而保留下来的狭长地带。绿道还含有“景观道”的意思,在英格兰南部,绿道也指存在于丘陵地带的古道或者环保车道,类似于我们所说的山脊路。废弃的老铁路和公路、曾经的运河河道,甚至荒废的工业用地都是绿道的雏形,其中,以废弃铁路形成的绿道最为常见。大部分绿道位于城市中,少部分在乡下,例如美国新罕布什尔州(New Hampshire)南部郊外的苏纳皮山丘绿 Greenway means the narrow strip that has not been developed by the government and preserved for leisure or environmental purposes. The greenway also contains the meaning of “landscape road”. In southern England, the greenway also refers to the ancient road or green lane that exists in the hilly area, similar to what we call the ridge road. Abandoned old railroads and highways, former canals and even abandoned industrial sites are the prototypes of greenways, of which the greenways formed by abandoned railways are the most common. Most of the greenways are located in cities, with a few in the countryside, such as the Sunapi Hills in the southern suburbs of New Hampshire
