| Research Abstract |
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.
