| 摘 要： | 为研究本世纪淮河中游气候与环境波支的湖泊沉积响应，１９９１年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＾１２６Ｐｂ、＾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年代中期为延结

| Abstract: | The history of climatic and environmental fluctuation of Nushan Lake in this century is reconstructed based on the data of high-resolution climatic and environmental proxies of the lake sediments and the time series of 1904 - 1991 buildt up by 137Cs and 210Pb dating. The results suggest that during the beginning 20 - 30 years of this century, there was lower temperature and higher humidity in Nushan Lake area. Then, in the period of the 1940-1950's. the temperature reached to the maximum, but cooled down in the 1960's andwarmed up after 1970. After then, the humidity changed freguently until the middle of the 1980's. when the climate in the area became a little humid again.It is noticeable that the above conclusions coincide with that from the deta of historical and instrumental records of this area. So the method used here can provide evidences for reconstruction of climate and environment change on a short time scale of lack-instrumental records area. |
