Picea schrenkiana tree-ring chronologies development and vegetation index reconstruction for the Alatau Mountains, Central Asia

, 2018
In this study, a total of 176 tree cores from Schrenk spruce (Picea schrenkiana) were used to establish a tree-ring chronology and a 167-year July–October normalized differential vegetation index (NDVI) for the Alatau Mountains in Central Asia was ...

Age-Effect Radial Growth Responses of Picea schrenkiana to Climate Change in the Eastern Tianshan Mountains, Northwest China

, 2017
The climate changed from warm-dry to warm-wet during the 1960s in northwest China. However, the effects of climate change on the response of radial growth from different age-class trees have been unclear.

Humid and cold periods in the last 5600 years in Arid Central Asia revealed by palynology of Picea schrenkiana from Issyk-Kul

, 2020
Central Asia, with its high mountains, despite its location between Europe and eastern Asia remains a data poor area. However, mountain glaciers are strongly affected by global change and have a wide-ranging impact. A new pollen record over the last 5600

天山北坡不同环境条件下雪岭云杉(Picea schrenkiana)林限土壤属性

, 2008
为了研究干旱区天山北坡中山带长达1000余公里的单建群种山地针叶林的空间分布原因,选择精河、玛纳斯、阜康和巴里坤中山带作为四种不同的环境条件,通过对不同环境条件雪岭云杉(Picea schrenkiana)上、下限土壤的采样与分析,探讨土壤因素对天山北坡中山带雪岭云杉分布的控制作用。雪岭云杉在天山北坡的连续分布主要是水热组合条件和土壤因素相互作用的结果,上、下限土壤属性变化与环境条件变化间存在着紧密的联系,表现为降雨量丰富的玛纳斯林区土壤肥力较高,但CaCO3含量较低 ...

Impacts of Global Warming on the Radial Growth and Long-Term Intrinsic Water-Use Efficiency (iWUE) of Schrenk Spruce (Picea schrenkiana Fisch. et Mey) in the Sayram Lake Basin, Northwest China

, 2020
Global warming and the sharp rise in atmospheric CO2 concentrations have a profound impact on forest ecosystems. To better manage these changes, a comprehensive understanding of forest ecosystem responses to global change is essential. There is a lack of

Evolutionary history of Purple cone spruce (Picea purpurea) in the Qinghai-Tibet Plateau:homoploid hybrid origin and Pleistocene expansion

, 2014
Hybridization and introgression can play an important role in speciation. Here, we examine their roles in the origin and evolution of Picea purpurea, a diploid spruce species occurring on the Qinghai–Tibet Plateau (QTP).
