[Radial growth responses of four coniferous species to climate change in the Potatso National Park, China].

Using the principles and methods of dendrochronology, we measured tree-ring width of four dominant coniferous species, ., var, , , and , in the Potatso National Park, and established the tree-ring width resi-dual chronologies. We analyzed the correlation of tree-ring width residual chronologies with daily and monthly climate data from the Shangrila meteorological station to analyze the response of radial growth to climate factors. The results showed that var had the highest annual growth rate, and had the lowest. Radial growth showed species-specific responses to climate changes, with the highest sensitivity of var and the lowest sensitivity of . Ring-width chronology of correlated positively with mean temperature during previous winter (November and December) and current summer (July). Ring-width chronology of var correlated positively with temperature during the early-growing season (June), but negatively with precipitation and relative humidity. Ring-width chronology of correlated positively with precipitation and humidity but negatively with maximum temperature during the early-growing season (May), indicating that its radial growth was primarily influenced by water availability during the early-growing season.
