Urban Development in Ryukyu Kingdom

1.舜堡的形成与发展利用史料研究的成果，从新的角度考证了舜堡在中世纪的变迁，研究了中世纪舜堡的功能与组成、布局、宇宙学、外花园等基本问题，阐明了它们的意义。探讨了迁都时期蜀里的城市形态和空间结构，考察了城市轴线运动、社会=空间结构及其特色的历史背景。我展示了琉球的风水思想可以追溯到古代琉球时代。此外，还证明了琉球-日本-中国的政治、社会和文化关系在《书里》的空间结构中得到了反映。并证明了一个有趣的事实，它应该被称为“二元性”。为了把握东中国海与中国隔开的琉球和日本“京都”的特殊面貌，笔者与东亚的“京都”进行了比较历史考量，并从空间的角度具体阐明了▲和京都的特点。此外，还邀请了日本、中国、韩国和台湾的研究人员，举办了以“东亚资本：在权威与私有化之间”为主题的国际研讨会，并取得了很好的成果。国际港口城市那霸的形成与发展利用地理信息系统技术恢复了琉球时代那霸的地理面貌。我解决了城市居民原有的地方形成和发展过程。例如，琉球王国开发港口城市，华侨华人开发居住地。他们统一为拿哈的过程就解决了。

1. Formation and development of imperial castle Shun castle and Shun Taking advantage of the result of research about the historical records, I have proved the changes of the Shun castle in medieval times from a new viewpoint, studied fundamental matters about function and composition, arrangement, cosmology, and an outer garden of the imperial castle Shun in medieval times, and clarified their meanings.I have explored the urban form and space structure of Shuri of the time of the transfer of the capital, and examined a historical background about movement of a city axis, society=space structure, and its special feature. I showed that the feng shui thought of Ryukyu went back to the time of old Ryukyu. Moreover, it was proved that politics, society, and a cultural relation with Ryukyu-Japan-China were being reflected in the space structure of Shuri. And the interesting fact which should be called "duality" was proved.2. "Kyoto" in East▲Asia of medieval timesIn other to grasp the special feature of "Kyoto" of Ryukyu and Japan separated from China by the East China Sea, I have performed comparison historical consideration with "Kyoto" in East Asia and concretely clarified characteristics of Shun and Kyoto from the spatial viewpoint. Moreover, I invited the researchers of Japan, China, South Korea, and Taiwan, held the international symposium focusing on "East Asian "Capitals": Between Authority and Privatization", and got the great result.3. Formation and development of international port city NahaThe geographical feature of Naha of the old Ryukyu age was restored by utilizing the technique of GIS. I solved original local formation and developmental process by city residents. For example, development of the port city by Ryukyu Kingdom and development of residence place by overseas Chinese. And the process which they unify as Naha was solved.
