| Outline of Final Research Achievements |
Analytical results for lacustrine sediments and lake-catchment system survey in East Asia (Mongol, China, Korea, Japan and Taiwan) reveal that: 1) gradual aridification (cooling) began in late-mid Holocene and artificial influences began at about 1000 yrs ago in Northeast China, 2) comparatively rapid aridification (cooling) began in late-mid Holocene and clear artificial influences were detected at about 100 yrs ago in central Taiwan, and 3) clear volcanic activity and post-environmental changes were detected since 1640 in the little ice age period and clear artificial changes after the world war 2nd were detected in lacustrine sediments of North Japan. Observation results in a small lake-catchment system in central Japan reveal that a combination of physical parameters may be available for identifying natural erosion-sedimentation processes from artificial ones.
