Abstract

The availability of both ancient and modern wood samples enables the Chinese fir (Cunninghamia lanceolata) in Central East China to become a potential tree species for dendroclimatic reconstruction over the Common Era. However, the potential of using tree-ring α-cellulose oxygen isotope ratios (δ¹⁸OTRC) in Chinese fir for the purposes of cross-dating and climatic reconstruction remains unexplored. Here we presented three δ¹⁸OTRC chronologies (1954–2006 CE) for the whole-ring (δ¹⁸OWR), earlywood (δ¹⁸OEW), and latewood (δ¹⁸OLW) in Chinese fir. The results indicated that the δ¹⁸OWR had the highest correlation among individual trees. Using the δ¹⁸OWR instead of the conventionally employed TRW can facilitate the cross-dating procedure. The δ¹⁸OWR, δ¹⁸OEW, and δ¹⁸OLW exhibited the strongest relationships with the hydroclimate variables during the entire (June–September), early (June–July), and late (August–September) summer, respectively. The climate conditions preceding the growing season had a stronger influence on δ¹⁸OEW than δ¹⁸OLW. Using the δ¹⁸OWR and δ¹⁸OEW to reconstruct the hydroclimate variations may result in greater bias than the use of δ¹⁸OLW. Our study demonstrated that the δ¹⁸OTRC in Chinese fir from Central East China has the potential for cross-dating and summer hydroclimate reconstruction.
