摘　　要：利用红松(Pinus koraiensis)和鱼鳞云杉(Picea jezoensis var.komarovii)这2树种分布上限的树轮样本,分别建立细胞个数(CN)、平均细胞腔直径(MLD)、最大细胞腔直径(MAXLD)及树轮宽度(TRW)标准年表,并分析了各树轮年表与1958—2002年月气温、月降水量的相关关系,从细胞尺度上揭示2树种径向生长对气候要素的响应.结果表明,红松和鱼鳞云杉的CN与TRW均有很好的相关性;MLD、MAXLD能够反映与TRW不同的气候信息,主要表现在红松MLD、MAXLD与前一年10月气温呈现正相关关系,鱼鳞云杉MLD、MAXLD与当年8月降水呈现正相关关系;气温和降水均是红松和鱼鳞云杉径向生长的限制因子,红松生长主要受到前一年冬季气温和降水及生长季6、7月气温的影响,而鱼鳞云杉生长主要受到生长季前期2月气温及生长季初期4月降水的影响.Pinus koraiensis and Picea jezoensis var.komarovii are two dominant conifer species in the Changbai Mountain Nature Reserve of China.Standard chronologies for cell number,mean lumen diameter, maximum lumen diameter and tree-ring width were constructed from tree-ring samples collected at each species’ upper elevational limits.Chronologies were correlated with climatic factors of monthly mean temperature,sum of precipitation for 1958-2002.Cell number and tree-ring width standard chronologies were found to have good relationship for the two species;Mean lumen diameter and maximum lumen diameter could record different climatic signals,with climatic signals recorded by tree-ring width.Mean lumen diameter and maximum lumen diameter of Pinus koraiensis were positively correlated with October temperature in the prior year,while mean lumen diameter and maximum lumen diameter of Piceajezoensis var.komarovii were positively correlated with August precipitation in the current year;Both precipitation and temperature are limiting factors for radial growth.Pinus koraiensis growth mainly was limited by winter temperature and precipitation in the prior year, and June and July temperature in the growth year.Piceajezoensis var.komarovii growth were limited by prior February temperature and current April precipitation.
