摘要:
通过对我国现代气候条件下发育的22个土壤剖面发育指标的分析,运用相关性分析方法建立了土壤发育指标与气候因子的关系—转换函数,并将之运用于辽宁朝阳凤凰山古土壤剖面古气候参数重建中,得出71~423 ka BP以来的古气候参数值:403~423 ka BP期间年均降雨量为523.92~574.42mm,年均温为10.6~11.0℃;311~403 ka BP期间年均降雨量为1184.6~1277.2mm,年均温为15.6~16.6℃;243~311 ka BP期间年均降雨量为517.24~669.08mm,年均温为9.18~12.2℃;225~243 ka BP期间年均降雨量为1302.7mm,年均温为16.5℃;208~225 ka BP期间年均降雨量为642.54~731.42mm,年均温为10.1~11.6℃;176~208 ka BP期间年均降雨量为1231.4mm,年均温为16.0℃;148~176 ka BP期间年均降雨量为640.49~682.09mm,年均温为8.49~9.13℃;71~148 ka BP期间年均降雨量为1128.2~1294.0mm,年均温为16.1~16.6℃。辽宁朝阳现今全年平均气温9℃,年均降水量450~500mm,说明该地区42万年以来气候有过多次波动,但总的趋势是由温暖湿润向寒冷干旱演化。

Abstract:
Through analysis of the soil development indices of 22 soil profiles developed under the modern climatic conditions of China and then correlation analysis, transfer functions were established between soil development indices and climate factors and used in reconstructuring paleoclimatic parameters of the paleosol profiles in the Fenghuang Mountain of Chaoyang, Liaoning Province. The following paleoclimatic parameters of the past 71 ~ 423 ka BP were obtained, including the mean annual precipitation being 523.92~574.42mm and the mean annual temperature being 10.6~11.0℃in 403 ~ 423 ka BP; 1184.6~1277.2mm and 15.6~16.6℃ in 311 ~ 403 ka BP; 517.24~669.08mm and 9.18~12.2℃ in 243 ~ 311ka BP; 1302.7mm and 16.5℃in 225 ~ 243 ka BP; 642.54~731.42mm and 10.1~11.6℃in 208 ~ 225 ka BP; 1231.4mm and 16.0℃in 176 ~ 208ka BP; 640.49~682.09mm and 8.49~9.13℃in 148 ~ 176ka BP; and 1128.2~1294.0mm and 16.1~16.6℃in 71 ~ 148ka BP. Now the mean annual temperature is 9℃ and the mean annual precipitation 450~500mm in Chaoyang, Liaoning, which indicates that although the climate of this area fluctuated greatly several times in the past 420,000 years, a general tendency is clear that the climate in that region is evolving from warm and humid to cold and arid.
