Advances in streamflow reconstruction using tree-ring data

Streamfbw reconstruction based on tree-ring data is an important direction in dendrochronology.In this study, tree-ring reconstructions of streamflow are described on the basis of the principle of dendrohydrology.The methodologies for reconstructing streamflow using tree-ring are introduced, and major advances in the subject are reviewed over the world.We will then focus on the review of nationalprogresses of tree-ring studies emphasizing on aspectsof studying regions, approaches andmethodobgies, and applications.Inadequate aspects in tree-ring researches and prospects of dendrohydrobgy studies are also proposed.It is clear that the tree-ring reconstructed long teffn streamflow series contains valuable infornation for better management of water resources and planning in river basins.
