Northern China has experienced dramatic drying since the 1960s CE. However, the scarcity of long-term observations hampers the evaluation of recent drought variations from a long-term perspective. Here, we present a tree-ring-width chronology of Chinese pine (Pinus tabuliformis Carr.) from the...

To explore the difference in the response of the radial growth of Pinus tabulaeformis and Picea crassifolia on different timescales to climate factors in the eastern part of Qilian Mountains, we used dendrochronology to select four different timescales (day, pentad (5 days), dekad (10 days), and...

Based on the combination of two dendrochronologies, the annual mean temperature from May to June for the last 160 years was reconstructed in Weichang region, China, with the predictor variables accounting 43.3% of the variance during the calibration period of 1956-2012. Warm periods with...

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...

Introduction: Global climate change can affect the sensitivity of tree radial growth to climate factors, but the specific responses of tree radial growth to microclimate along the altitudinal gradient in the long term are still unclear. Methods: In this study, the tree-ring width chronologies of ...

Climate transition zone is a sensitive area of climate change and ecological transition where forests are vulnerable to climate extremes. Extreme droughts are increasing in frequency and magnitude under climate change, resulting in structure and function changes of forest ecosystems. Here, to...

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...

Carbon and oxygen isotope ratios (δ¹³C and δ¹⁸O) were measured in annual tree-ring cellulose samples dated from 1756 to 2015 CE. These samples were extracted from Chinese pine (Pinus tabulaeformis Carr.) trees located in a semi-arid region of north-central China. We found that tree-ring δ¹³C and δ...

Tree-ring chronologies of Pinus tabulaeformis from three sampling sites in southeastern Gansu Province in China and growth-related parameters calculated from daily average temperatures were utilized to explore the response features of tree radial growth to onset and cessation date, duration and...

Compared with traditional research methods, research based on physiological processes could provide more interactions between the radial growth of trees and climate factors. The Vaganov-Shashkin model (VS-oscilloscope) was applied to simulate tree-ring formation in semi-arid eastern Gansu, China...
