摘　　要：发展新区是国内外历史城市保护与发展的基本策略之一。但我国历史城市发展新区时常常采用以旧城为中心、对称布置的空间结构,虽然缓解了用地和人口压力,但交通期望线仍然以旧城为核心,反而加剧了旧城的交通集聚和拥堵,导致拆房拓路对历史格局的破坏。对比中西城市和交通发展的历史与现状,我国为保护历史城市而发展的新区空间布局宜采取"偏"在旧城一侧的双核结构,或不以旧城为几何中心的多核结构,将旧城作为以历史文化保存为特色的"副中心",另设综合性的现代城市"主中心",彼此间以不穿越历史城区的快速路相连。Development of new zones is an internationally acknowledged strategy for conserving historic cities. In the Chinese context, new zone developments often takes a symmetrical spatial structure centered on the historic urban area. Such a structure can to some extent help relieve population and land-use pressure, but it nevertheless treats the historic urban area as the focal point of many origin-destination traffic lines and hence aggravates the problems of traffic concentration and jams. Compared with western cities, Chinese historic city conservation should develop new zones to form a parallel or multiple-nuclear structure. In these solutions, the historic urban area is not the spatial center but a sub-center focusing on history and culture while the primary city center is located in new zone so that connective expressways need not cross the historic urban area.
