Discussions on cave stalagmite as substituting index of paleoclimate significance

Modern global climate change became a hot issue of universal concern.A hot issue of global change research was to obtain one hundred year or even decades to obtain and distinguish the rules on climate change.As a key to restore the ancient climate,study the evolution of ancient environment,the cave stalagmite was characteristic of many advantages,and would play an increasingly important role in the study of paleoenvironment.In lights of current research situation,the authors reviewed the micro-layer contrast on laminated layer of stalagmite,the formation mechanism of micro-level,stable isotope record,trace element record,the growth rate and other aspects of micro-layer light-emitting.
