The tree ring has been used widely in the study of historical climate reconstruction, growth-climate and treeline dynamics due to its advantages of accurate cross-dating, high resolution and good continuity. Tree-ring formation is not only determined by tree growth but also influenced by different...

We selected Larix principis-rupprechtii Mayr. in the Liupan Mountains area as a research object, dividing different competition levels of L. principis-rupprechtii Mayr. by using the intersection angle competitive index, established tree-ring width chronology of L. principis-rupprechtii Mayr. by...

Aims: We aim to compare the climatic representativeness of blue intensity (BI) and ring width index (RWI) in Picea jezoensis, and to provide guidance for the further application of BI parameters in dendrochronology. Methods: A total of 120 tree-ring cores were extracted from P. jezoensis trees in...

Douglas fir(Pseudotsuga sinensis), as a kind of the national class II endangered tree species, has been attracting comparatively less attention on its dendroclimatology so far instead. A standard tree-ring width chronology was established based on the tree-ring sample cores collected from Zhenping...

Objective: The Qinling Mountains is the most typical distribution area for Larix chinensis-dominant temperate coniferous forests in China, and also one of the most significantly vulnerable areas affected by climate change worldwide. In this study, we aim to understand the sensitivity of L....

Objective: Exploring the stand productivity in the forests with different densities and its response to climate change is helpful for the functional assessment and adaptive management of forest ecosystems. Method: In this study, the net primary productivity (NPP) of natural Mongolian pine (Pinus...

Objective: This paper researched the influence mechanism of climate factors on radial growth of Pinus tabulaeformis to provide basis for building P. tabulaeformis artificial forest with high stability and sustainability in semi-arid loess area. Method: Two average trees were chosen from each...

In order to test whether the relationship between climate and the radial growth of trees is affected by altitude, altitude variability and time stability of climate-influenced radial growth of a dominant conifer, Chinese pine (Pinus tabulaeformis), in the eastern Qilian Mountains were studied...

Using the Heilongjiang Fenglin National Nature Reserve (128°58'-129°15'E, 48°2'-48°12'N) as the experimental site, we measured and calculated the growth whorl width of Pinus koraiensis, the dominant tree species in the broad-leaved red pine forests in the Xiaoxing'an Mountains, and applied the...

Objective: Because Scotch pine (Pinus sylvestris) plays an important ecological role in windbreak, sand fixation and farmland protection and so on in the north of China,we discussed the characteristics of the chronology of its tree rings in different age-classes and the relationship between its...
