解釋
林區氣候-
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
尤其是在過去全球變化pages研究中，埋藏古木纖維素中的碳氫氧同位素分析已成為環境演化研究的主要量化手段。另外，對于中國這樣典型的季風氣候國家，開展樹輪穩定同位素隨季節性變化的研究具有重要的意義。我國在樹輪研究方面起步較晚，研究方法和研究內容上也比較簡單，還存在不小差距，既要進一步積累基礎資料，又要做區域對比，加強與相關學科的交叉研究。 -

The probability distributions of climatic elements are discussed. based on the characters of them, a multimode model is introduced and verified through the nonlinear fitting. the climate features of quasi - biennial oscillation of the stratospheric zonal wind over equator, the enso index, the surface pressure at reykjavik 21 90w 64 13n and swedish temperature, and the northern hemisphere tree ring all show that the multimode are universal in the climatic system
對氣候要素的概率分佈進行了討論，根據這些概率分佈的特點提出了多模態模型，並用非線性擬合的方法進行了驗證。對赤道平流層緯向風enso指數esi序列冰島reykjavik 21 . 90w ， 64 . 13n氣壓和瑞典溫度北半球樹木年輪等數據的分析表明：氣候系統中多模態現象具有普遍性。
