Changes in hydro-geomorphological environment in eastern Asia due to anthropologenic activities during the past 50 years

对云南、中国和日本的一些湖泊集水系统的分析表明，它们不仅对水文和地震活动有响应，而且对人类活动也有响应：1)湖泊沉积物的物理化学性质与集水区环境变化有关；2)日本湖泊沉积物的平均矿物粒度变化与降雨强度有关；3)云南湖泊沉积物中存在地震活动；4)云南湖泊的相对沉积速率与降雨强度、集水区平均坡度和集水区裸露面积大小大致成正比(与人类学有关)。

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).
