从分析中国东北地区城市内部空间结构发展演化的基本历程出发,总结了东北地区城市内部空间结构的基本特征和城市空间形态的基本模式,并在此基础上分析其独特的内在问题、外部形势、动力机制与空间重构的方向选择。东北地区城市内部空间结构呈现如下基本特征:城市圈层结构比较明显;城市核心区进一步强化,“多中心”格局尚未形成;“退二进三”彰显成效,“工业包围城市”痕迹严重;正在进入一个城市迅速外延的发展阶段;空间扩展呈现多元化特点。
This paper proceeds from the forming of the urban internal spatial structure and development in northeast China, summarizes the basic characteristic of the urban internal spatial structure and the basic patterns of the urban spatial morphology, and on this basis analyzes its unique intrinsic question, exterior situation, the power mechanism and the spatial restructuring choice of direction. The urban internal spatial structure presents the following basic characteristic: the circle structure is quite obvious; the urban core area further strengthens, the "multi- centers" pattern does not yet form; "Draws back two and enters three" reveals the result, the trace of "the industries surrounds the city" is serious; it is entering the development phase of urban rapid extension; the spatial expansion presents the multiplication.
