摘要：

Tree-rings call provide continuous yearly paleoclimatic records for regions or periods of time with no instrumental climate data. However, different species respond to different climate parameters with, For example, some sensitive to moisture and others to temperature Here, we describe four common species growing in Northern Ireland and their suitability for climate reconstruction. Our results suggest that beech and ash tire the most sensitive to climate. with tree-ring widths more strongly influenced by precipitation and soil moisture in early Summer than by temperature Or Sunshine. Oak is also sensitive to surnmer rainfall, whereas Scots pine is sensitive to maximum temperature and the soil temperature. We find that the moisture-related parameters, rainfall and the Palmer Drought Severity Index (PDSI), and to a lesser extent, maximum and mean temperatures, call be reconstructed Reconstructions of climate parameters with tree-rings as proxies may be relatively stable for some seasons such as May-July. We find that combinations of species are more successful in reconstructing climate than single species. (C) 2009 Elsevier GmbH. All rights reserved.
