Ancient Capital and City's Enviroment in Japan

本研究旨在从环境的角度加深对日本古都和城市的认识。因此，我们得出了以下结论。首先，山脉和河流曾经是决定首都、大斋府和其他城市位置的主要因素。其次，澄清了都城建设后，出于礼制的需要，试图保持都城的精神纯净和围绕都城的山形。第三，通过对历史记录的重新审视，我们否定了一个普遍的观点，即政府在选择新京城的位置时，倾向于将封绥制度应用于周围的山脉和河流。为了让公众了解我们的结论，我们出版了一份分两卷的报告；一个是收集历史文献，另一个是收集研究论文。

The aim of our research is to deepen the understanding of Japanese ancient capitals and cities from environmental viewpoint.As a result, we came to the following conclusions. The first was that mountains and rivers used to be primary factors in deciding the location of the capitals,Dazaifu and other cities. Secondly, we clarified that after the constructions of capitals, out of the necessity of Li, attempted to keep the spiritual purity of the capitals and the shape of mountains surrounding the capitals. Thirdly, through the re-examination of historical records, we came to deny a common view that when the government selected the location of the new capitals, they tended to apply the Feng sui system to the surrounding mountains and rivers. To make our conclusions known to the public, we published a report in two volumes; one gathers historical documents and the other is a collection of research papers.
