Retrospective Analysis of Tree Decline Based on Intrinsic Water-Use Efficiency in Semi-Arid Areas of North China

Long-term tree growth is significantly affected by climate change, which have become a global concern. Tree-ring width and isotopic information can show how trees respond to climate change on a long-term scale and reveal some phenomena of tree decline or death. In this study, we used isotopic techni...

Tree-ring width and isotopic information can show how trees respond to climate change on a long-term scale and reveal some phenomena of tree decline or death. In this study, we used isotopic techniques and investigated annual changes in carbon isotope composition and tree-ring width of <i<Populus simonii Carr.</i< in Zhangbei, as well as trends in tree-ring carbon discrimination (Δ<sup<13</sup<C) and iWUE in normal, mildly declining and severely declining trees, in order to make a retrospective analysis and further understand the process of tree decline. We found that there were significant differences (<i<p</i< < 0.01 **) in δ<sup<13</sup<C, Δ<sup<13</sup<C, c<sub<i</sub< and iWUE at different decline stages, meaning that the δ<sup<13</sup<C and iWUE could be new indicators of tree health. The iWUE of all groups increased significantly, while the growth rate of declined <i<P. simonii</i< was much higher than that of normal growth <i<P. simonii</i<. According to the analysis, there may be a threshold of iWUE for healthy trees, which once the threshold value is exceeded, it indicates that trees are resistant to adversity and their growth is under stress. Similarly, the changing trend of BAI supports our conclusion with its changes showed that tree growth became slower and slower as degradation progressed. iWUE inferred from tree-ring stable carbon isotope composition is a strong modulator of adaptation capacity in response to environmental stressors under climate change. Elevated annual temperatures and increased groundwater depth are all contributing to the decline of <i<P. simonii</i< in north China.

abstract	Long-term tree growth is significantly affected by climate change, which have become a global concern. Tree-ring width and isotopic information can show how trees respond to climate change on a long-term scale and reveal some phenomena of tree decline or death. In this study, we used isotopic techniques and investigated annual changes in carbon isotope composition and tree-ring width of <i<Populus simonii Carr.</i< in Zhangbei, as well as trends in tree-ring carbon discrimination (Δ<sup<13</sup<C) and iWUE in normal, mildly declining and severely declining trees, in order to make a retrospective analysis and further understand the process of tree decline. We found that there were significant differences (<i<p</i< < 0.01 **) in δ<sup<13</sup<C, Δ<sup<13</sup<C, c<sub<i</sub< and iWUE at different decline stages, meaning that the δ<sup<13</sup<C and iWUE could be new indicators of tree health. The iWUE of all groups increased significantly, while the growth rate of declined <i<P. simonii</i< was much higher than that of normal growth <i<P. simonii</i<. According to the analysis, there may be a threshold of iWUE for healthy trees, which once the threshold value is exceeded, it indicates that trees are resistant to adversity and their growth is under stress. Similarly, the changing trend of BAI supports our conclusion with its changes showed that tree growth became slower and slower as degradation progressed. iWUE inferred from tree-ring stable carbon isotope composition is a strong modulator of adaptation capacity in response to environmental stressors under climate change. Elevated annual temperatures and increased groundwater depth are all contributing to the decline of <i<P. simonii</i< in north China.

Tree-ring width and isotopic information can show how trees respond to climate change on a long-term scale and reveal some phenomena of tree decline or death. In this study, we used isotopic techniques and investigated annual changes in carbon isotope composition and tree-ring width of <i<Populus simonii Carr.</i< in Zhangbei, as well as trends in tree-ring carbon discrimination (Δ<sup<13</sup<C) and iWUE in normal, mildly declining and severely declining trees, in order to make a retrospective analysis and further understand the process of tree decline. We found that there were significant differences (<i<p</i< < 0.01 **) in δ<sup<13</sup<C, Δ<sup<13</sup<C, c<sub<i</sub< and iWUE at different decline stages, meaning that the δ<sup<13</sup<C and iWUE could be new indicators of tree health. The iWUE of all groups increased significantly, while the growth rate of declined <i<P. simonii</i< was much higher than that of normal growth <i<P. simonii</i<. According to the analysis, there may be a threshold of iWUE for healthy trees, which once the threshold value is exceeded, it indicates that trees are resistant to adversity and their growth is under stress. Similarly, the changing trend of BAI supports our conclusion with its changes showed that tree growth became slower and slower as degradation progressed. iWUE inferred from tree-ring stable carbon isotope composition is a strong modulator of adaptation capacity in response to environmental stressors under climate change. Elevated annual temperatures and increased groundwater depth are all contributing to the decline of <i<P. simonii</i< in north China.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">tree-rings</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">climate change</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">carbon-isotope discrimination</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">iWUE</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">tree decline</subfield></datafield><datafield tag="653" ind1=" " ind2="0"><subfield code="a">Meteorology.
