%X About 214 trees in 9 sampling sites, representing 5 endemic conifer species,were collected from the western Sichuan province and eastern Qinghai province,China.In this study,we try to investigate tree-ring sensitivity to climate change in order to reconstruct past climate from this region.All the 5 species present distinct ring boundaries with few ABS(absent rings) and are available for cross-dating.They all passed the test by program COFECHA.Statistics for all the 8 residual chronologies also exhibit significant inter-correlation between series and high values of mean sensitivity.These results indicate the usefulness of these chronologies for dendrochronological studies.Pearson correlation analyses were applied to provide a basic estimate of the causal relationships between tree-ring width and climate factors.We found some significant relationships between tree-ring width and temperature as well as precipitation.Regardless of tree species,chronologies in the study area presented accordant variations of which may reveal strong common climate signal.Thus these chronologies are shown to be dependable for building tree-ring network in the near future. However,there was limitation in this study,only monthly mean of temperature and precipitation were available.Also,for this typical subtropical mountain system,meteorological stations are usually located in valleys and biased to represent moisture conditions on the slopes.Thus the estimation of precipitation both in temporal and spatial domain was rather restricted.Further studies,such as wood anatomy,physiology and densitometry,are needed for better understanding the environmental and climatic history in this area.
