【摘要】 碳同位素技术对碳素在生态系统中的迁移动态具有很好的示踪作用,在生态学各领域研究中应用广泛。土壤、大气、植物是森林生态系统的重要碳库,植物是大气和土壤交换碳元素的重要介质。本文简要总结了碳同位素技术在研究碳元素在植物体内以及植物、土壤、大气碳库之间的迁移规律和生态学过程中的应用,展望了该技术在森林界面学中的应用前景。更多还原

【Abstract】 Carbon isotope technique is one of the credible and effective techniques in ecological research,which can efficiently trace the dynamics of carbon transfer in ecological systems,and has been extensively applied in many fields of ecology.Soil,atmosphere and plant are the important carbon pools in forest ecosystem,among which,plant is the main medium linking the carbon exchange between soil and atmosphere.In this paper,the patterns and ecological processes of carbon transfer among soil,atmosphere and plant were summarized,with the application prospects of carbon isotope technique in forest interfaces research discussed.更多还原
