| 摘 要： | 用青海省东南部斑玛地区的一个云杉年表与其周围的单站和区域的气象要素反复校准和验证，发现该云杉年表对其临近的单站或所在区域的盛夏降水都有委强的响应，并确认了这种关系显著且稳定，说明了它可以反映青海高原东南部夏季降水的变化。而它与各月气温和冬、春、秋季降水均无明显无关。因此我们用它重建了该地区盛夏（７月）２６５年（１７２３～１９８７年）雨量。并对重建的区域降水进行了统计分析。

| Abstract: | Annual growth records from tress at Banma region in the southeastern Qinghai Plateau are correlated positivly with variations of summer precipitation and used to reconstruct the regional precipitation variation in the past.In a series of tests,it is shown that the relationship between the climate and tree ring variables is statisticlly significant and stable with time,confirming the power of dendroclimatic reconstruction in arid and semi arid region such as the south eastern Qinghai Plateau. |
