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).

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、地震活动有响应，而且对人类活动也有响应：1）湖泊沉积物的理化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）云南湖泊沉积物中记录有地震活动;（4）云南湖泊的相对沉积速率与降雨强度、流域平均坡度、流域裸露面积大小（与人类学有关）大致成正比。
