| Research Abstract |
12 sediment cores were recovered from Fukami - ike lake. A bout 3% of annual laminae in average were missing from the core. It is revealed that biomization method was powerful enough to detect slight change of vegetation. Quantitative climate reconstruction by best modern analogue method performed well to reconstruct autumn and winter temperature, but it did not reconstruct slight change of precipitation. The performance was better when sediment of 20 - 30 years was analyzed.
