中文摘要：
基于长白山低海拔区的红松年轮样本,建立树轮宽度和细胞尺度参数的7个标准年表;选取部分树轮年表与东岗气象站1959—2007年前一年9月到当年9月的月均气温、月均最高气温、月均最低气温、月降水量进行相关分析;并分析1988年气候突变前后红松年轮指数年表与气候要素的关系.结果表明：所建立的7个标准年表中,细胞个数与轮宽年表的相关性最好;降水和气温都是长白山低海拔区红松树木生长的限制因子,但树轮与降水的相关关系略好于气温,主要表现为与前一年9月和当年5、6月降水的相关达显著水平.细胞大小比轮宽能反映出更多气候信息,主要体现在细胞大小年表与当年3月气温和5月降水呈正相关关系,与当年5月气温呈负相关关系;1988年气温发生升高突变后,树轮对气候要素的响应发生了变化,主要表现为细胞大小对气候要素响应的敏感性降低,与气候要素相关的月份有所提前.
英文摘要：
Based on the tree ring samples of Pinus koraiensis collected from the low altitude areas of Changbai Mountains, seven standard chronologies for tree ring width and cell scale parameters were constructed. Parts of the chronologies were chosen for the correlation analysis with the climate elements in 1959-2007 at Donggang meteorological station, and the changes of the correlations between tree ring indices and climate elements before and after 1988 in which the climate changed abruptly were discussed. In the seven standard chronologies constructed, cell number had the best correlation with tree ring width. Both precipitation and air temperature were the limiting factors for the growth of P. koraiensis, but the chronologies had better correlation with precipitation than with air temperature, mainly manifested in the significant correlation between the chronologies and the precipitation in previous September and current May and June. Comparing with tree ring width, cell size could reveal more climatic information, mainly manifested in the positive correlation between the chronologies and the air temperature in March and the precipitation in May, and the negative correlation between the chronologies and the air temperature in May. After the abrupt change of air temperature in 1988, the responses of cell size to climate elements had some changes, mainly manifested in the decreasing sensitivity to monthly climate elements and the earlier response time.
