通过对1991年5月－1992年10月间采自江苏固城湖和安徽女山湖的3个沉积孔往中人工放射性核素137Cs比度垂直分布的分析研究，发现在该地区切尔诺贝利核事故泄漏137Cs有明显的蓄积，其峰值与核武器试验导致的1963年134Cs时标最大蓄积峰值相当，具有同样的时标意义。因此，在苏皖地区这一137Cs蓄积峰值对研究现代湖泊沉积、水土流失和区域环境变化等都有重要价值。
Based on the analysis of the vertical distribution of 137Cs ratio of artificial radionuclides in three sedimentary holes collected from Gucheng Lake in Jiangsu Province and Nushan Lake in Anhui Province from May 1991 to October 1992, it was found that in the region Chernuoh The 137 Cs leakage caused by the Bailey nuclear accident has a significant accumulation, and its peak value is equivalent to the maximum peak accumulation value of 134 Cs time scale in 1963 caused by the nuclear weapon test, which has the same significance of time scale. Therefore, the peak value of 137Cs in Jiangsu and Anhui Provinces is of great value for studying the sedimentation, soil erosion and regional environmental changes in modern lakes.
