To estimate the response of glacier ecosystems to the global environmental change, we studied ecology of glacier microorganisms and albedo reducing process by microbial activities on the glaciers of various types by field studies at various part of the world. By comparing microbial flora, surface structure, albedo and environmental conditions on glaciers of various types, we could clarify relationship between glacial microbial flora and environmental condition, basic information needed to understand glacial microbial activities and how it affect glacier albedo.

为了估计冰川生态系统对全球环境变化的响应，我们通过在世界各地的实地研究，研究了冰川微生物的生态学和微生物活动对各种类型冰川的反照率降低过程。通过比较不同类型冰川的微生物区系、表面结构、反照率和环境条件，我们可以阐明冰川微生物区系与环境条件之间的关系，了解冰川微生物活动及其对冰川反照率的影响所需的基本信息。
