摘要： 利用燕山地区几个主要植物的花粉-气候响应面模型,定量恢复了燕山南部5 000 a B.P.来的气候变化。5 000 a B.P.以来,燕山南部的气候曾发生过两次明显的降温事件,一次发生在4 500~3 600 a B.P.,7月份平均气温比今低2.0℃左右;一次发生在2 750~1 750 a B.P.,7月份平均气温比今低3.7℃左右;2 000 a B.P.以来年均降水量一直呈下降趋势,年均降水量比2 000 a B.P.前减少50~100 mm。孢粉分析表明,燕山南部人工栽培板栗的历史可以追索到1 600 a B.P.,种植水稻的历史可以追索到700 a B.P.。

Abstract: Climatic changes of Yanshan Mountain area since 5000 a B. P. had been reconstruted using several major pollen-climate response surface models. Two serious climate decline events took place during the past 5000 years. One was in the period of 4500-3600 a B. P. with mean July temperature 2.0℃ lower than that at present. Another was in the period of 2750-1750 a B. P. with mean July temperature 3.7℃ lower than that at present. Since 2000 a B. P., the mean annual precipitation reduced gradually. The present mean annual precipitation is about 50-100mm lower than that 2000 a ago. Pollen analysis shows that Castanea trees had been cultivated about 1600 years, and Oryza had been planted for 700 years in the southern part of Yanshan Mountain.
