| 摘 要： | 通过青海高原不同区域的多条树轮年表和青海高原温度的统计分析，探讨了用多条树轮年表重建整个青海高原年平均气温的途径和方法。高原上树轮年表与温度存在较好的对应关系，温度是年轮变化的主要控制因子之一，特别是树轮年表较好地反映了最低气温的变化。树轮年表中差值年表(RES)对温度变化的反映最好。本文用6条树轮年表资料重建了青海高原近250年的年平均气温序列。 |

| Abstract: | Through the statistic analyses of temperature and multi-piece tree-ring chronology in different regions over Qinghai Plateau, the method and way of annual mean surface air temperature reestablished by multi-piece tree-ring chronology over Qinghai Plateau are discussed. It is found that the air temperature and tree-ring chronology have a good corresponding relationship, the air temperature is one of main controlling factors of the tree-ring change, especially the chronology can reflect the change of minimum temperature. the difference chronology in the tree-ring chronology is the best one to reflect temperature change. By using the data of six tree-rings chronology, annual mean surface air temperature sequences over Qinghai Plateau in recent 250 years are reestablished. |
