  1. Tree ring is a kind of natural archives, on which the isotopic analysis is important to study global climate and environmental change. the authors mainly provide a comprehensive introduction to the fractionation models of carbon, hydrogen and oxygen isotope in plants, their research techniques and the extract methods from cellulose. that results show isotopic tracer can record the message of climatic variation and has become a powerful tool for paleoclimate reconstruction and for the modern environment changing research. especially studying on pages, the cellulose isotopic analyses of imbedded old tree ring have become the mainly quantitative means of environmental evolvement. in addition, china is a typical monsoon country, research in tree ring stable isotope seasonal variation can give us a lot of important information on that. up to now, the research techniques and works on tree ring in our country are still in its earlier stage, and remain many limitations. it needs further accumulate basic research materials, intensify regional contrast and intercross studies on relative subjects
