The leaching and transferring of 95zr in different soils and its actions in several aquatic and terraneous ecosystems were studied by using the isotope tracer techniques. this would provide some basic data for illustrating the behavior of 95zr in different agricultural ecosystems and serve as science according for establishing some safety standard and managing pollution. at one time, environmental pollution arising by poisonous pollutes has been global hotspot problem
本文採用同位素示蹤技術研究了~ （ 95 ） zr在不同土壤中的淋溶、遷移和在幾種水生及陸生生態系統中的行為，為探明~ （ 95 ） zr在不同農業生態環境中的行為規律提供基礎資料，對制定有關安全標準和污染治理提供了科學依據。 -
The global change study is one of the most spectacular and interesting environment scientific questions in the 1990 s. the message of global change stores in tree rings, ice core, loess, underground water, lake sediment and deep sea sediment, all these proxies record the information of global change. with the advances in stable isotope techniques, the isotopic tracer records the message of climatic variation and becomes a powerful tool that can understand paleoenvironment reconstruction and modern environment changing
全球變化研究是90年代以來最為引人注目和關切的環境科學問題之一。全球環境變化的信息儲存於樹輪湖泊冰芯黃土地下水和海洋沉積物等載體中，隨著穩定同位素技術的發展，同位素示蹤劑指示環境變化的信息，成為了解古環境再造和現代環境信息變化的一個強有力的工具。 -
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。 -
3 the distributive dynamics of 95zr absorbed in crucian and the behavioral trait of 95zr in an aquatic ecosystem was studied by using isotope - tracer technology, and the mathematical model was confirmed by application of nonlinear regression method
3 、研究了卿魚對952 :的吸收和在其體內的分佈動態以及95zr在水生生態系統中的行為特性，並運用非線性擬合方法建立其數學模型。 -
