 note = {学位論文の要旨, 博士論文全文, Feng Shui is based on empirical observations of the surrounding landform. Majority of researches on Feng Shui in Okinawa concern the historical study, or analyze village layout from perspectives of history, folklore, and architecture. However, a comparative study of Feng Shui in Okinawa with that in mainland topography is little reported. This study aims to clarify a Ryukyu village’s features, focusing on Feng Shui trees and village landscape. 
(1) In China, and Korea, Feng Shui trees are commonly symbolical separated patches. Some major species include Cinnamomum camphora, Ficus microphylla,and Acer buergerianm(Mainland China, and Hong Kong) and Pinus densiflora (Korea). In Okinawa, forests are functionally used to embrace the house, the village, and the coastline to contain the strong wind. Feng Shui trees include Fukugi, Calophyllum inophyllum, Pinus luchuensis, Pandanus odoratissimus, and Hibiscus tiliaceus in Okinawa. 
(2) A Feng Shui village landscape highlights the surrounding landform to "contain the wind" and "accumulate the water" in China and Korea. In Okinawa, village houses are encircled by multilayer forest belts of house-embracing trees, Kusatimui in the rear and Village Ho:go together to embrace the village, and coastline Ho:go. Such a layout, designed to protect the village from the winter wind and typhoons, is attributed to the environmental difference between mainland and island topographies. 
(3) Fukugi trees that embrace all sides of the house are not found in Korea, or China. House-embracing trees and interlaced road network are the features of a Ryukyu Feng Shui village. In Okinawa, there are always one to four houses embraced by Fukugi. 
(4) Distribution layout of house-embracing Fukugi was reproduced with HO CAD software. Along with houses mostly backing north and facing south, forest belts in the north, east, and along the coastline are thick in Okinawa. Such layout of Fukugi is assumed as countermeasure to winter wind and typhoons. 
(5) House-embracing Fukugi trees are under routine care and management to maintain Feng Shui’s function. Tree number in every meter of the woodlands was 3.1 in Tonaki, and 2.7 in Bise, respectively. The estimated mean and oldest tree ages were 40 and 179 in Tonaki, and 46 and 266 in Bise. The mixture of diverse ages of trees, and proper density might be assumed as the result of proper management. 
(6) All village roads are not straight, but courteous in Okinawa. No intersections are perfect right angle. Fukugi tree lines are laid out along the roads which decline from the north-south or east-west axes. Such a layout has been planned to contain the wind according to Feng Shui principle of "to contain the wind and to accumulate the water". The curvous roads are able to channel and reduce the damage of the strong winds coming to the village. 
In summary, Feng Shui in Okinawa, which was adapted to the severe nature of winter wind and typhoons in summer, utilizes tree planting to achieve an ideal Feng Shui environment. Comparing with mountainous Feng Shui practice in China and Korea which highlights the landform and symbolically use Feng Shui trees, Feng Shui in Okinawa is functionally practiced, thus, an "Island Ryukyu model of Feng Shui" is argued in this study., 連合農学研究科博士論文(農学) ; 学位取得日: 平成20年3月14日},
