Groundwater　contamination　risk　assessment　is　an　important　basis　to　support　the　protection　of　the　groundwater　ecological　environment.　In　this　research,　the　groundwater　contamination　risk　in　typical　karst　areas　in　China　was　evaluated　by　PLEIK　model　(P:　protective　cover;　L:　land　use;　E:　epikarst　development;　I:　infiltration　conditions;　K:　karst　development)　and　classification　and　discrimination　methods　were　used　to　assess　groundwater　vulnerability　and　pollution　source　load;　the　water　quality　index　method　was　used　to　assess　the　status　of　groundwater　contamination　in　the　research　area.　The　results　show　that　groundwater　vulnerability　values　in　the　research　area　range　from　3.04　to　7.79,　and　most　areas　have　low　groundwater　vulnerability.　Groundwater　pollution　loading　indexes,　in　the　region　of　the　pollution　sources,　gathered　numerical　up-water　quality　status　evaluation　that　shows　that　most　of　the　regional　groundwater　quality　in　the　research　area　has　good　groundwater　at　present.　The　groundwater　contamination　risk　assessment　results　show　that　the　groundwater　pollution　risk　is　mainly　at　a　very　low　level　in　most　areas　of　the　study　area,　but　the　groundwater　pollution　risk　is　higher　in　the　areas　where　the　pollution　sources　gather.　The　result　reveals　that　the　regional　groundwater　contamination　risk　level　for　regional　groundwater　ecological　environment　protection　provides　a　theoretical　basis　for　policy　making.
