Application of carbon isotope technique in forest ecosystem carbon cycling research

Abstract

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.

Key words: Poplar clone, Osmotic stress, Photosynthesis photoinhibition, Reactive oxygen species, Protecting enzymes, 6-BA, AsA
