Characteristics of Tree-ring Width Chronologies and Their Response to Climate for Different Elevations in Manasi River Basin
摘要
Abstract
Tree-ring cores taken from six sites at different elevations in Manasi River Basin were used to develop six tree-ring width chronologies. Combining the two chronologies of which located near the upper limit of the forest to create the MNU chronology and combining the three chronologies of which located near the lower limit of the forest to create the MNL chronology, while the LBW chronology was regarded as the MNM chronology. By comparing the parameters of the three standardization chronologies and their response to climate change ,the results indicated that:(1)express population signal (EPS)、mean sensitivity (MS)、signal-to-noise ratio (SNR) and Autocorrelation order 1 (AC1) decreased within increasing elevation.(2) The amount of high frequency information decreased and within increasing elevation and that of the low frequency information increased within increasing elevation.(3)Temperature was the main climatic limiting factor for the MNU chronology. For the MNL chronology and MNM chronology, the precipitation played a positive role and the temperature exerted indirect retroaction, and their correlation had obvious physiological significance.关键词
