城市广场,被人们誉为“城市的名片”,世界上许多著名的广场,已成为所在城市的象征与标记。过去,广场的布局大都采用与马路同高的“平面型”,如北京的天安门广场。20世纪以来,各国建筑师锐意创新,使一些别开生面的“空间型”广场陆续问世,给人以耳目一新之感。加拿大温哥华市的罗勃逊下沿式(又称“凹型”)广场,地坪就比马路降低约4米。这个广场还有宽阔的带有“之”字型坡道的台阶,与旁侧的省联政府办公楼的天坛花园相连接。花圃和各式坐椅错落布置其间。下沿的地坪,平时是露天餐厅,冬季作溜冰场,夏夜用于文艺演出,南北台阶便成了天然看台。 The city square has been hailed as the “city’s business card.” Many of the world’s famous squares have become the symbol and mark of the city. In the past, most of the layout of the plaza used the “planar type” of the same height as the street, such as Tian’anmen Square in Beijing. Since the 20th century, architects of various countries have been making innovations and innovations, which have enabled some of the unique “spatial” plazas to come out one after another, giving people a fresh and new look. The Robson Down (also called “Concave”) Square in Vancouver, Canada, is about 4 meters lower than the road. The square also has a wide step with a zigzag ramp, connected to the Tiantan Garden on the side of the provincial government office building. Flower beds and all kinds of chairs are arranged in different places. The floors along the lower floors are usually open-air restaurants, winter skating rinks, summer nights for theatrical performances, and the north and south steps become natural stands.
