Other Abstract


Based on tree-ring width measurements of Abies fabri Craib distributed in the upper and the lower elevational limits in Hailuogou,Gongga Mountain,the tree-ring chronologies were constructed by using three different detrending methods,including the negative index curve ( NEC) ,the regional curve standardization ( RCS) and the basal area increment ( BAI) . We combined temperature and precipitation data from neighboring
Kangding meteorological station,to analyzed the response of radial growth in A. fabri to climatic factors in the different methods. The results showed that the chronology developed by BAI could more accurately characterize the growth trend of A. fabri. The correlation analysis between BAI chronology and monthly climatic factors indicating
the radial growth in the lower elevational limits was negatively correlated with temperature from June to September in the previous year,and temperature was the main influencing factor in the lower elevational limits. Radial growth in the upper elevational limits was positively correlated with temperature in July of the current year,as well as precipitation in May of the current year. The coupling effect of temperature and precipitation was the main factor affecting the radial growth of A. fabri distributed in the upper elevational limits.
