Moon Lake is one of the volcanic crater lakes at the Aershan-Chaihe volcanic field in the middle part of Daxing’an Mountain Range, located at the current northern margin of the East Asian monsoon. Pollen records of 8.86 m-long sediment core of Moon Lake reveal the vegetation evolution and climate change since the Late Glacial. The climate events are comparable with other global and regional high-resolution paleoclimate records, revealing the Moon Lake sensitively record the global and regional climate change and high-resolution pollen analysis of study area is a good indicator of East Asian monsoon strength change.
