ABSTRACT 摘要Why are those historic central districts divided into different named areas?为什么历史中心区被命名为不同的区域？Is there any spatial mechanism of defining and/or generating those areas as the parts of the cities?是否有某种空间机制来定义或生成这些区域作为城市的一部分？this paper explores what kind of geometric and spatial mechanism might account for the formation of the area structure represented by the periodic patchwork pattern (if their relationship is verified in the second phase),本文探讨了以周期性拼凑格局为代表的的区域结构形成的几何空间机制（如果他们的关系能够在第二阶段被证实）。and make the first step towards understanding the part-whole problem discussed in the book of Spaceis the Machine.并且迈出了第一步，了解《空间是机器》此书中讨论的部分-整体问题。This will allow us to explore the spatial laws causing partitioning of the urban network into different parts.这将使我们能够探索将城市网络划分为不同部分的空间规律。On these grounds, it finally seeks to propose a new heuristic model of area boundary– embodied by spatial discontinuity -in relation to the change rate of street density.在此基础上，本文提出了一个新的区域边界启发式模型，该模型以空间不连续性为代表，与街道密度变化率相关。
