| Research Abstract |
Analyses of some lake-catchment systems in Yunnan, China and Japan show that they respond to not only hydrological and seismological activities but anthropologenical activities: 1) physical and chemical properties of lake sediments are related to environmental changes in the catchment areas; 2) changes in average mineral grain size of Japanese lake sediments are correlated to rainfall intensity; 3) seismic activities were printed in lake sediments in Yunnan, 4) relative sedimentation rate in Yunnan lakes are roughly proportional to rainfall intensity, average slope of catchment area, and size of bare area in the catchment areas (anthropologeically related).
