Abstract: In this paper, a master tree-ring width chronology of ancient Chinese pine in Zhaoling of Shenyang was developed, which included three chronologies, i.e., Standard, Residual, and Arstan chronology. The chronologies had significant correlations with the extreme minimum temperatures in January and April, precipitation in February, and yearly water vapor pressure. They had strong responses to the water vapor pressures in April, May, September and October, and significantly correlated with RES chronology. The chronologies had higher correlations with yearly, April, May, June, September, October and November relative humidity, among which, the correlations with yearly and May relative humidity were significant. The yearly and most monthly evaporation had negativeeffects on Chinese pine growth, with significant correlations between chronologies and May evaporation, but positive correlations were observed between chronologies and January evaporation. The Chinese pine growth in Shengyang was also affected by the global and hemisphere temperature anomalies. There were 32 extreme drought years corresponded to the extreme narrow or narrow rings in the chronologies during 1700～2004. Solar activity in 1703～2004 and geomagnetic activity in 1868～2004 also affected the chronologies, with high correlations between sunspot number and geomagnetic sudden commencement for STD chronology and ARS chronology, respectively.There were 11 yr, 23 yr and 50 yr common periodical band between solar activity and Chinese pine chronologies, and 10.5 yr, 20 yr and 45 yr common periodical band between geomagnetic sudden commencement and Chinese pine chronologies.
