Advances in studies on relationships between tree-ring stable carbonisotope and climate change

The growth of trees is closely relative to the environment and is influenced by the climatic changes. As an important parameter to show the climatic and environment changes, tree-ring stable carbon isotope has been paid more attention and applied by lots of ecologists. In this paper, the mensuration method of tree-ring stable carbon isotope, the relationships between tree-ring stable carbon isotope and the climatic factors such as CO2 concentration, precipitation, temperature and solar irradiation time were reviewed. The application of tree-ring stable carbon isotope in the investigation of paleo-climate reconstruction was discussed. Some suggestions were put forward for the further development of tree-ring stable carbon isotope study.
