街道景观空间的保护与更新

摘要：中国传统城市在城市空间形态上表现为“墙”与“街”相结合的形态。墙是对不同内容的生活进行划分与聚合的手段，街是对不同层面的生活进行联系与疏导的手段。前者是城市生活领域的标志，后者是城市生活场景的标志。现代城市景观理论中的街道景观空间包括线性和区域两个方面的内容。其中，线性空间指的是街道以及街道与河流的复合空间形态，而区域景观一般指与街道紧密联系的节点型景观空间如中心区，广场，城市节点等。对与一些具有封闭形态的城市单元景观，例如政府大院，学校，住宅区等，其内部的道路系统不属于街道景观空间研究的范围之内。线性和区域景观构成了城市外部空间的主体。

西安作为“世界四大古都”之一，在中国城市建设史上具有不可替代的作用,西安，古称长安,又曾称西都、西京、大兴城、京兆城、奉元城等,是中国历史上建都朝代最多、历时最久的城市，因而城市中遗存了大量的历史风貌区。

由于历史的不可逆性及唯一性，在数千年的历史中留下的许多文物，建筑，街区，文化等，都成为一个城市的稀缺潜在资源。这些资源所能带来的巨大社会效益和经济效益在这些年都得到了广泛的共识。很多的城市依托其本身的历
