区域空间秩序营建的技术方法是中国古代人居环境规划设计体系的重要组成部分。隋唐时期奠定了中国古代文化中人文创造的基础，都城长安地区的区域空间秩序营建对其他国家与后世中国影响深远。既有规划设计方法研究主要集中在城市尺度，区域尺度研究以历史地理、区域经济等为主，隋唐长安地区区域空间秩序营建的技术方法研究具有重要学术价值和广阔空间。.本课题基于复杂性科学“复杂问题有限求解”方法开展针对性研究，主要采用以GIS空间分析为核心的实证分析方法，在重构与模拟区域空间形态的基础上，开展多尺度、关联性空间分析，解析区域空间秩序营建的技术方法，进而探讨其现实意义。.本课题创新之处体现在：1，在区域尺度上探讨中国古代空间秩序营建的技术方法，是空间规划设计研究的新领域之一；2，运用多尺度GIS空间分析与史学定性研究相结合的研究方法，在古代规划设计方法研究中具有创新性；3，研究成果为当代区域文化遗产保护提供理论支持。

The methods and technology of constructing regional spatial order are an essential part of the human settlement planning and design system in ancient China. The construction of regional spatial order of the capital region – Chang’an Area in Sui-Tang Dynasties (581-907AD) had a profound influence on both the later dynasties of China and the foreign countries then. Because it is in Sui-Tang Dynasties when the humanistic foundation of ancient Chinese culture was laid. The existing research on the methods and technology of planning and design is mainly limited to the city scale, and most region-scale studies are focused on the historical geography and the regional economy. Therefore, the research on the methods and technology of constructing the regional spatial order of Chang’an Area in Sui-Tang Dynasties can fill the gap of existing research, and contribute to our understanding of the planning system in ancient China..Based on the main idea of complexity science, this research aims to achieve limited resolutions in specific research. GIS techniques will be used to carry out multi-scale spatial analysis and correlation analysis for empirical study. Through reconstructing and simulating the regional spatial form of Chang’an Area, this research aims to examine the methods and technology used in constructing the spatial order, and analyze its contemporary significance..The main contributions of this research are: (1) the research of methods and technology of constructing spatial order at the region scale has rarely done before, and thus is one of the newest fields in planning and design research; (2) the integration of multi-scale GIS spatial analysis with qualitative historical research leads to an innovative method in the study of ancient planning and design methods and technology; (3) it will provide a theoretical support for the regional cultural heritage conservation of Xi’an Area and other regions in China.
