北京——都市计划的无比杰作

  林徽因

 

由建筑学家谈城建历史,细腻简明, 写的好!

虽然 地质科学上 不那么准确:

北京的高度约为海拔五十公尺,地质学家所研究的资料告诉我们,在它的东南面比它低下的地区,四五千年前还都是低洼的湖沼地带。所以历史家可以推测,由中国古代的文化中心的"中原"向北发展,势必沿着太行山麓这条五十公尺等高线的地带走。因为这一条路要跨渡许多河流,每次便必须在每条河流的适当的渡口上来往。当我们的祖先到达永定河的右岸时,经验使他们找到那一带最好的渡口。这地点正是我们现在的卢沟桥所在。“

其实

据地质学家和考古学家考证

华北平原 北起内蒙通辽红山和山海关,南至河南腹地,西以太行山恒山燕山山脉为界, 东至渤海黄海,还包括了淮河流域,南到长江北岸,这一大片地区,在大约7700年之前,不是陆地,而是海域,间或有个别岛屿,如山东崂山等。

因此 在这个大区域内,至今似乎尚未见7500年以上的文物古迹。
