摘要/Abstract

摘要： 以庐山自然保护区3个不同海拔样地采集的138根日本柳杉样芯为研究材料，利用树木年轮学方法分析其径向生长与季节和月气候因子的响应关系。结果表明：低海拔处日本柳杉径向生长对气候因子的响应相比于中、高海拔更敏感；中、低海拔径向生长与春季相对湿度呈显著正相关（P<0.05），低海拔径向生长与春季日照时数、夏季均温呈显著负相关（P<0.05），而中海拔径向生长与夏、秋季均温呈显著负相关（P<0.05）；高海拔径向生长与各个季节气候因子表现出一定的相关性，但相关性不显著；3个海拔径向生长均与当年1月均温呈显著正相关（P<0.05），中、低海拔径向生长与上年7月及当年7月均温呈显著负相关（P<0.05），高温会抑制树木的生长，低海拔径向生长与当年4月空气相对湿度、降水量呈显著正相关（P<0.05），与当年4月日照时数呈显著负相关（P<0.05），随海拔的升高相关性降低；庐山日本柳杉径向生长与主要气候要素之间的相关性呈现出明显的季节性，日本柳杉径向生长主要受上年7及7月均温和4月空气相对湿度的影响，海拔是影响日本柳杉径向生长对气候因子响应的重要因素，最终建立的标准年轮宽度年表适合进行树木年轮气候学的研究。

Abstract: A total of 138 Cryptomeria japonica cores were collected at three different elevations in Lushan Nature Reserve. The relationship between radial growth and seasonal and monthly climate factors was analyzed by dendrography. Tree ring width of C. japonica at low elevation was more sensitive to changes of climatic factors than that at medium and high elevation. Radial growth was positively correlated with spring relative humidity at low elevation and middle elevation (P<0.05), negatively correlated with sunshine hours in spring and autumn mean temperature at low elevation (P<0.05), and negatively correlated with summer mean temperature and autumn mean temperature at middle elevation (P<0.05). There was a certain correlation between radial growth and climate factors in each season at high elevation, but the correlation was not significant. Radial growth was positively correlated with mean temperature of three different elevations in January (P<0.05) and negatively correlated with mean temperature in July of previous year and July of current year at low and middle elevation (P<0.05). High temperature would inhibit tree growth. Radial growth was negatively correlated with relative humidity, precipitation (P<0.05), positively correlated with sunshine hours (P<0.05) in April at low elevation, and decreased with the increase of elevation. The correlation between radial growth of C. japonica and main climatic factors in Lushan Mountain varied among different seasons. Radial growth was mainly influenced by the temperature in July and July of the previous year and the relative humidity in April. Elevation was an important factor affecting the response of radial growth to climatic factors. The standard annual ring width chronology established here was suitable for the study of tree ring climatology.
