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.

从深池湖中发现了 12 个沉积岩芯。平均每年有约 3% 的纹层从核心缺失。结果表明，生物群化方法足以检测植被的微小变化。采用最好的现代模拟方法进行的定量气候重建在重建秋冬季温度方面表现良好，但没有重建降水的微小变化。当分析20-30年的沉积物时，性能较好。
