结论水藻是年代性沉积物。碳酸盐阀门记录碳酸钙的年降水量。冰川湖泊的阀门记录了每年一次的冻结。瑞士的湖泊提供了可以监测生物生产力年度变化的实地地点，并且可以识别长期气候变化。我们对湖泊沉积物的研究不仅有助于了解现代湖泊沉积，而且有助于深入了解气候、生产力和沉积之间的相互关系。
ConclusionsVarves are sediments registering annual events. Carbonate varves register annual precipitation of calcium carbonate. Glacio-lacustrine varves record an annual freeze-over. The Swiss lakes provide field sites where annual changes of biologic productivity can be monitored, and where secular climatic variations can be recognized. Our investigations of lake sediments have helped not only to understand the modern lacustrine deposition, but also to develop an insight into the interrelations between climate, productivity, and sedimentation.
