Methods for quantifying and evaluating the material dynamics in lakes and their watersheds were developed using the vertical distributions of materials and isotopes, the contents of particulate matter in inflowing rivers during rainfall periods, the isotopes in surface and groundwater as the tracers on time scales, sources, and processes. The regime shifts in water quality and ecosystems were detected in Lake Kasumigaura and then their causes were discussed.

提出了以物质和同位素的垂直分布、降雨期间入湖河流颗粒物含量、地表和地下水中的同位素作为时间尺度、来源和过程的示踪剂来量化和评价湖泊及其流域物质动力学的方法。分析了鹿儿湖水质和生态系统的动态变化，并对其原因进行了探讨。
