黑松（Pinus nigras subsp. laricio）和松属（Pinus pinaster）树木年轮纤维素的氧同位素年内模式沿海拔梯度可分为4种不同的模式：（1）年轮初期高值，之后呈下降趋势;（2）年轮初期低值，之后呈上升趋势;（3）年轮中期高值;（4）整个年轮呈下降趋势。这些模式反映了对当地立地条件和不同水源的依赖性。ContextIntraneous氧同位素年代学从树轮纤维素可以作为一个代理过去的气候条件在跨-或甚至在季节内resolution.AimsWe探索这些年代学的潜力从松树（PinusnigraJ.F.落叶松和PinuspinasterAiton）生长在地中海岛屿的科西嘉，法国，沿着海拔梯度范围从海平面到1600米asl.MethodsWe开发了高分辨率的年内氧同位素年表从树轮纤维素从5个站点沿着海拔梯度。分析期间涵盖了十年2007-2016年的七棵树和1987-2016年期间的一棵树，分别为resultsThe年表显示树木，网站和年份之间的高变异性。我们确定了四种不同的年内氧同位素模式，反映了树木生长对不同水源（生长季节降水与深层土壤水库）和生长季节气候条件的依赖性。在沿海站点的树木有机会获得地下水，而在高海拔地区生长的树木主要依赖于在生长季节降水作为watersourc.ConclusionThe不同的模式可以归因于不同的水源的使用。覆盖30年的年内年表表明，在2007年之后，干热夏季的频率增加。
Key messageIntra-annual oxygen isotope patterns of tree-ring cellulose fromPinus nigrasubsp.laricioandPinus pinasteralong an elevation gradient can be divided into four distinct patterns ((1) high values in the beginning of the tree ring, declining trend afterwards; (2) low values in the beginning, increasing trend afterwards; (3) high values in the middle of the tree ring; (4) declining trend over the whole tree ring). These patterns reflect the dependency on local site conditions and different water sources.ContextIntra-annual oxygen isotope chronologies from tree-ring cellulose can serve as a proxy for past climate conditions at inter- or even intra-seasonal resolution.AimsWe explore the potential of these chronologies from pine trees (Pinus nigraJ.F. Arn subsp.laricio(Poiret) Maire var Corsicana Hyl. andPinus pinasterAiton) growing on the Mediterranean island of Corsica, France, along an elevation gradient ranging from sea level to 1600 m asl.MethodsWe developed high-resolution intra-annual oxygen isotope chronologies from tree-ring cellulose of eight trees from five sites along the elevation gradient. The analysis period covers the decade 2007–2016 for seven trees and the period 1987–2016 for one tree, respectively.ResultsThe chronologies show a high variability between trees, sites, and years. We identified four different intra-annual oxygen isotope patterns which reflect the dependency of tree growth on different water sources (precipitation during the growing season vs. deeper soil water reservoirs) and climate conditions during the growth season. Trees at coastal sites have access to groundwater, while trees growing in high elevations mostly depend on precipitation during the growth season as water source.ConclusionThe different patterns can be attributed to the use of different water sources. The intra-annual chronology covering 30 years indicates an increasing frequency of dry-warm summers after 2007.
