Development of Chinese pine tree-ring width chronology in Fuling Mausoleum, Shenyang of northeastern China

In this paper,a Chinese pine master tree-ring width chronology(including three chronologies:standard chronology,residual chronology and arstan chronology) for Fuling Mausoleum in Shenyang,northeastern China was developed.Close relations between Chinese pine tree-ring width chronologies and local low temperature variables in winter(prior November-February)as well as in early spring(April-May) were found,and the correlations between the chronologies and January along with February temperatures were more significant than that of the other time;there were significant correlations between chronologies and the precipitation of January as well as February,and there were also significant correlations between chronologies and the water vapor pressure of January and September;relative humidity of prior October-prior November,September and May-June of the same year had significant influence on Chinese pine tree-ring width;the evaporation had significant negative effects on Chinese pine growth during almost the whole time,and this effect was most significant in May,however,positive effects in January and February also existed.Nearly 35 extreme drought years producing narrow or narrowing rings were recorded in the chronologies from year 1650 to present. Some significant common periodicity bands between Chinese pine tree-ring width chronologies and solar activity,geomagnetic sudden commencement were also detected.
