项目摘要

In this research, environmental changes and reconstruction of former landscapes in various regions were investigated based on the interpretation of recently declassified intelligence satellite (Corona Satellite) photographs from U.S. Geological Survey, of maximum ground resolution in 2-3 meters and being able to obtain 3 dimensional image. In addition, satellite images of LANDSAT TM and SPOT were also used. And following results were obtained ;1) In the Turpan Basin, Northwest part of China, the precise locations of the wall surrounded castle towns and their circumference ruins, such as watchtowers and Buddhism temples, and their terrestrial conditions were investigated. Differences in terrestrial conditions of main ruins became clear, and the karez system in the basin was considered to be started at the Turpan oasis from 15^<th> Century.2) General characteristics of landforms along the main valleys in western Bhutan and hazards of natural disaster due to mass movement and a flood were discussed based on landform changes detected from photo-interpretation and field survey.3) Based on an old map drawn in 1862 and large scale aerial photographs, land use change at the Site of Fortified Magistrate's Office at Hakodate built in the Middle of 19th Century in Hokkaido has been discussed.4) Characteristics the ancient Mesopotamian cities and detail cities plan of the Taxila ruins in the eastern part of the Peshawar Basin, Pakistan were discussed based on interpretation of Corona satellite photographs.5) Characteristics of resent decrease of the water area surrounding the Lake Dongting of China has changed from filling up the branches of the Yangtze River to land reclamation by drainage.

本研究利用美国地质调查局最近解密的情报卫星（Corona Satellite）照片进行判读，研究了各地区的环境变化和以前景观的重建，该卫星的最大地面分辨率为2-3米，能够获得三维图像。此外，还使用了LANDSAT TM和SPOT的卫星图像。1）研究了吐鲁番盆地城垣及其周边的碉楼、佛寺等遗址的确切位置和地貌条件。主要遗址的地形条件差异变得明显，盆地中的坎儿井系统被认为始于15 ^世纪的吐鲁番绿洲。2）根据照片判读和实地调查发现的地貌变化，讨论了不丹西部主要山谷沿着地貌的一般特征以及由于群众运动和洪水造成的自然灾害的危害<th>。根据1862年绘制的旧地图和大比例尺航空照片，探讨了北海道世纪中期修建的函馆设防裁判所遗址的土地利用变化。4）白沙瓦盆地东部塔克西拉遗址的古美索不达米亚城市特征和城市细部规划。5）中国洞庭湖水域近期减少的特征已由长江支流的填海演变为排海造地。
