在中国古代都城规划史上，秦都咸阳具有继往开来的重要地位，秦都咸阳规划设计技术具有特别重要的学术价值。长期以来，学术界对秦都咸阳规划设计的基本理论、方法和技术尚缺乏系统的、令人信服的解释。在实现文化复兴与文化建设的现代化进程中，亟需填补这一学术空白。本课题针对古代都城规划设计研究中亟待解决的秦都咸阳规划设计难题，建构面向古代都城人居建设的"规画"观念，在其指导下探索秦都咸阳的规划设计方法，实践并发展人居环境科学理论。

Xianyang, the capital city in Qin Dynasty of ancient China, has a crucial role that brides the past and the future in the planning history of China's ancient capital cities. While the planning and design technology of Xianyang has special important academic value, scholars in planning field are in lack of a convincing explanation as well as systematic study on its theory, method and technology in terms of planning and design practices. It is urgent to fill this blank during the modernization process of cultural construction and Chinese cultural renaissance. This study focuses on addressing the planning and design problems of Xianyang, and intends to construct a theoretical framework of "GuiHua" concentrating on planning of human settlements in ancient capital cities. Based on this principle, the study develops the theory of human settlements sciences through exploring the planning and design method of Xianyang City.
