新疆夏尔希里1850-1870年森林生长抑制事件及启示
Suppression of Forest Growth from 1850 to 1870 and Its Implications in Xiaerxili,Xinjiang
摘要
Abstract
The occurrence and impact of extreme drought events are spatiotemporal differences.Expanding the information on extreme drought events on the spatio-temporal scale is helpful to understand their occurrence characteristics and accurately assess their impact.In this study,tree-ring samples of Picea schrenkiana Fisch.et Mey were collected in Xiaerxili,Xinjiang.The tree-ring width chronology was established,the relationship between radial growth and climate factors was analyzed to explore historical extreme climate events and their impacts.The results showed as follows:(1)There was a significant negative correlation between radial growth and vapor pressure deficit(VPD)in April,and this relationship was significantly enhanced recently;(2)A major forest growth decline occurred from 1850 to 1870,during which the radial growth rate of trees was the lowest over the past 300 years;(3)In the late period of forest growth decline event,some trees exhibited growth release phenomenon.These results indicate that the Xiaerxili experienced a super persistent drought event in the 1850s and 1860s,characterized primarily by atmospheric drought,which resulted in the radial growth of trees was inhibited or some trees even died.With the increasing trend of regional VPD,the risk of extreme drought events in Xiaerxili will also increase,and the risk of growth decline events and even large-scale death of Picea schrenkiana will further increase.It is suggested to strengthen the real-time monitoring of forest growth in Xiaerxili,accurately assess the health risks to forest growth,and develop corresponding measures for drought and disaster prevention.关键词
