| 摘 要： | 本文采用条件分位数调整法,对二类气候代用资料,华山树木年轮年表和西安旱涝等级序列进行合并尝试,既最大限度地利用在年轮资料中的连续变化信息,又能使历史文献资料可以与其相互补充、校准,从而使得合并出来的序列更有助于对过去气候的重建。

| Abstract: | Based on two kinds of proxy data,a tree-ring width chronology at Huashan and the wet-ness/dryness grade series around Xian in north-central China,this present study demon-strates how different types of proxy climate records can be combined to give a more reliableestimate of the climate in the past than either record candoindividually,With comparison andcorrection of the two data sets, various statistical models can be developed from individualand combined series. Among them, the best combined model produced by the conditionalquantile adjustment method can be selected for reconstruction of April-July rainfall atHuashan back to 1600A.D. |
