长白山红松和鱼鳞云杉年轮细胞尺度参数对气候要素的响应
RESPONSE OF TREE-RING CELL SCALE PARAMETERS TO CLIMATE ELEMENTS OF PINUS KORAIENSIS AND PICEA JEZOENSIS VAR.KOMAROVII IN THE CHANGBAI MOUNTAINS
摘要
Abstract
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.关键词
