The stable isotope structure(^<15>N-^<13>C map) was summarized for the ecosystems involving Mongol grassland and the Selenge - Lake Baikal watershed. The map could provide a baseline for the changes of above ecosystems under the future environmental changes with emphasis on global warming, drying and overgrazing.Cyclings of nitrogen and phosphorus were also studied with emphasis on the uploading of these nutrient by the grazing.Food-web structures of the pelagic and estuarine ecosystems in Lake Baikal were clarified on the L^<15>N-L^<13>C isotope map. The important roles of Ice-algae were demonstrated for the estuarine ecosystems.It was emphasized that Lake Baikal could be called as ‘Isotopically ordered natural laboratory'. These results were published in the book : DIWPA Series 4.

总结了蒙古草原和色楞格-贝加尔湖流域生态系统的稳定同位素结构（^<15>N-^<13>C图）。该地图可以为未来环境变化（重点是全球变暖、干旱和过度放牧）下上述生态系统的变化提供基线。还研究了氮和磷的循环，重点是放牧对这些养分的上传。阐明了贝加尔湖中上层和河口生态系统的食物网结构。 L^<15>N-L^<13>C同位素图。论证了冰藻对河口生态系统的重要作用，强调贝加尔湖堪称“同位素有序的天然实验室”。这些结果发表在《DIWPA Series 4》一书中。
