With the further study on groundwater pollution, research about earily waming of groundwater nas begun. l as papetr tesernubd ioneprogressive correlation among groundwater vulnerablity,risk assessment of groundwater polution and early waming of groundwater pollution.The classification methods of early waning of groundwater polution can be summarized into two categories, i.e. methods of early warning otgroundwater pollution based on the setting threshold and the established criteria, on the basis of summarying the research theory and methodsof groundwater vulnerability and risk assessement of groundwater at home and abroad. In the end, thts paper pontea out tna the signmncaace Jearly warning of groundwater polution in the sustainable development of groundwater resource,anad the resefatcn leunod ao uwolorau.and thgof early warning of groundwater pollution shouid be improved in crossing of multidisepinary, couping unhe aovanced lteononuR/ ua naccuracy of data.
