摘要:

植物稳定同位素是近年来在地理学、生态学研究中逐步广泛应用的研究手段, 具有综合长 期生物地球化学过程和联系不同系统成分的特点, 国际上已经展开了较为广泛的应用, 国内也有 相关研究。本文对国内外植物C、H、O 稳定同位素研究的回顾, 显示植物稳定同位素与环境因子, 如气温、湿度、降水、环境稳定同位素组成等密切相关。目前植物稳定同位素技术主要应用于历史 时期环境气候的重建, 恢复大气CO2 同位素组成以及CO2 浓度的变化趋势。本文根据植物稳定同 位素的特点和研究基础, 认为植物稳定同位素方法不仅可以用来重建历史时期气候, 而且在区域 环境差异及其生态效应研究上有着重要应用前景。

Abstract:

Stable isotopes in plants are widely applied in geographical and ecological studies in the recent years internationally, which combine long- term biogeochemical process and integrate different systemic components. Researches on stable isotopes of plants aim at studying temporal and spatial information of environmental factors, and revealing the trends of climate change and the geographical distribution characteristic. Abundant environmental and climatic information is recorded by stable isotopes in plants, such as information on temperature, humidity, precipitation and environment isotopes composition. The latest progresses over the world are reviewed in this paper, including the basic theories, research methods and main application areas. Review of researches on stable isotopes in plants on national and international literatures shows that stable isotopes in plants have close relation with environmental factors. The technology of stable isotopes in plants is mostly used to rebuild historical climate series, and recovers isotopes composition and concentration trends of CO2 in the atmosphere. Analysis of the features of isotopes in plants indicates that stable isotopes in plants could not only be applied to studying climate change, but also to detect regional environmental differences which has an important future for application. Study shows that the 18O in plants came only from H2O. Therefore, the origin of vapor in plants is one of the most important factors of the δ18O composition in plant, especially in typical monsoon regions. So it is possible to estimate the respective affected areas of different monsoons, and to study the spatial pattern of monsoon climate.

Key words: climate change, district environmental difference, fraction, plants, stable isotopes
