The response of radial growth to climate and the sensitivity tree at different ages in drought conditions are essential for predicting forest dynamics making correct management policies. In this study, we analyzed responsiveness Picea crassifolia Kom. explored relationship between age individual scale wetter eastern area drier western Qilian Mountains. Pearson correlation coefficients were calculated chronology each climatic factors examine climate-growth relationships. Linear fitting,...
Abstract Tree-ring δ13C and δ18O of dominant Dahurian larch Mongolia pine in the permafrost region northern Great Higgnan Mountains, China were used to elucidate species-specific ecophysiological responses warming temperatures increasing CO2 over past century. Larch stable carbon discrimination (Δ13C) 13C tree rings both showed synchronous changes during investigated period (1901–2010), but with isotopic atmospheric enriched warming. Δ13C controlled by maximum temperature moisture conditions...
The hydrogen and carbon stable isotope ratios (δ2HLM δ13CLM values) of tree-ring lignin methoxy groups have recently been recognized as valuable palaeoclimate indicators. However, the environmental factors but also sample preparation processes that might cause variations δ2HLM values not fully explored. Furthermore, temporal dynamics wood content on both isotopes hasn't investigated. To investigate effects total content, removal lipids differences between individual pooled series isotopic...
Particulate matter contributes much to the haze pollution in China. Meteorological conditions and environmental management significantly influenced accumulation, deposition, transportation, diffusion, emission intensity of particulate matter. In this study, temporal spatial variations PM10 PM2.5—and responses meteorological factors regulation intensity—were explored Xi’an, The concentrations were higher than those PM2.5, especially spring winter. mean annual PM2.5 markedly decreased from...
Dendroecological techniques were used to examine the relationships between topographic aspects, climate factors and radial growth of Picea meyeri Larix principis-rupprechtii in Luyashan Mountains, North-Central China. Four sites selected at timberline totally 67 trees 134 cores collected. Pearson correlation regression surface analysis conducted reveal growth-climate relationships. The results indicated that two species both showed significant negative correlations with temperature during...
Linking the response of tree growth to global warming is a key fully appreciating impact climate change on forests. To examine impacts temperature and precipitation growth, we studied radial Pinus tabulaeformis along an altitude gradient from 2032 m a.s.l. 2361 Helan Mountains, which almost northwestern limit P. distribution in China. The results showed that, decreased significantly (P <0.05) at low (2032 a.s.l.) remained steady middle high (2200 during past decades, was attributed different...
Increasing evidence suggests that extreme droughts cause more frequent tree growth reduction. To understand the consequences of these better, this study used tree-ring cores from nine sites to investigate how moisture and altitudinal gradients affect radial Picea crassifolia Kom., a common species in Qilian Mountains northwest China. The total annual precipitation mean temperature eastern region were higher than those western Mountains. trees showed stronger resistance drought west, as they...
The effects of climate warming are widely recognized; however, some studies have suggested that the rate has slowed since end twentieth century. However, relationships between and radial growth trees during different periods change yet to be investigated fully. In present study, tree-ring core samples were collected from Picea crassifolia Juniperus przewalskii in Qilian Mountains northwest China study growth. divided into two groups: one with significant tree-growth reduction another...
