泸沽湖2个针叶树种径向生长与气候因子的关系
Relationship Between Radial Growth and Climatic Factors of Two Conifer Species in Lugu Lake
摘要
Abstract
This paper analyzed the relationship between the characteristics of annual ring widths of the two species and their response to cli-mate change by using dendrochronology method.We established the residual chronologies of two species and analyzed the correlation between their radial growth and temperature and precipitation,so as to derive the main climatic factors affecting the radial growth of A.georgei and P.likiangensis in Lugu Lake.The results showed that temperature(negative correlation)in January and May,precipitation and drought index(positive correlation)in March and May were the key climatic factors affecting the growth of two tree species.In addition,the increase of pre-cipitation in September-December of the previous year was favorable to the radial growth of P.likiangensis.关键词
