| Abstract: | The IGCP 379 project, “Karst Processes and the Carb on Cycles” was proposed and organiged by Chinese scientists. Its duration time is five years from 1995 to 1999. In ths paper the research situation and its dev elopments have been presented.①The developments about the carbon cycle of the e pigenic karst system and the sources and sinks of CO2 in the at mosphere have three; Its study areas have been extended; The work processes of the carbon cycl e of the epigenic karst sy stem have been disclosed; The CO2 amounts uptaken by the epigenic karst system have been evaluated.②There are three aspects about the developments of the CO 2 releasing from Earth's depth:The more CO2 releasing zones have been discov ered; The sources of CO2 have been identified; The problems about the sources and sinks of CO2 in the Tibet have been argued furtherly. ③The developments a bout the paleoenviomental reconstruction with the karst records have three aspec ts:The temporal and spatial ranges have been enlarged remarkably; More and more new technologies and methods are used to attain more paleoenvironment informatio n; The resolution has been promoted continuously. |
