In this paper, we present the first annual oxygen isotope (δ 18 O) record (1902 to 2004) from the latewood cellulose of trees growing in a temperate-moist forest in southwestern China. Tree-ring δ 18 O ranges from 12.8 to 18.6‰ and averages 15.2‰. δ 18 O in the latewood negatively correlates with total cloud cover, relative humidity, and precipitation during the moist months...
It is important to understand the history and dynamics of climate in a transitional region between areas with different atmospheric circulation patterns, where the vegetation and ecosystems are vulnerable to environmental change. We investigated variations in the long-term oxygen isotope composition (δ 18 O) in tree rings of Qinghai spruce (Picea crassifolia) and their relationships to climatic...
