为研究本世纪淮河中游气候与环境波动的湖泊沉积响应，1991秋季在女山湖湖心提取了4．8m沉积物．对顶部20cm沉积物运用210Pb、137Cs的年代定位，获得1904－1991年湖泊沉积物的年序．以此通过高分辨沉积记录的代用标志提取，重建了本世纪女山湖气候与环境的变化过程．结果表明，本世纪最初20－30年女山湖地区温度偏低、湿度偏大；40、50年代为本世纪温度最高的时段，50至60年代中期为延续最长的偏湿时段．温度在60年代一度降低．70年代中期后回升并以正偏为主．其干湿在60年代中期后变化频繁，但80年代中期以后又趋暖湿．
In order to study the lacustrine deposition response to the climate and environmental fluctuations in the middle Huaihe River in this century, 4.8m sediments were extracted in the autumn of 1991 in the lake of Lianshan Lake. Chronostratigraphy of 210Pb and 137Cs was applied to the top 20 cm sediments, and the sequence of lake sediments from 1904 to 1991 was obtained. In this way, the changing process of the climate and environment of the Lake Ladies Lake in this century has been rebuilt through the substitution and extraction of high resolution sedimentary records. The results show that in the first 20-30 years of this century, the temperature in the Lake Women’s Lake is low and the humidity is too high. The 40 and 50 years are the highest temperature in this century, and the longest wet period in the 1950s and 1960s. The temperature dropped in the 1960s. After the mid-1970s rebounded and the main bias. Its wet and dry changes frequently after the mid-1960s, but it became warm and wet after the mid-1980s.
