Abstract:: The groundwater is the main water resources in karst areas.It is also one of the most important basic aspects in supporting the social economic development.The groundwater quality is affected by human activity to a large extent due to its intrinsic vulnerability.Based on more than 20 years’ hydrochemical data, taking Ji’nan spring basin as an example, the variations of groundwater chemistry and its relationship with human activity are analyzed.The results show that the groundwater has been deteriorated during the past 20 years.The groundwater quality varies not only in different areas but also in different time under the pressure of human activity.The groundwater quality in the east suburb is worse than that of the west and the centre and is deteriorating more rapidly.With the land use change and the enhancement of human activity, the groundwater pollution index rises from the indirect recharge area via the direct recharge area to the discharge area.The same variation happens from upper reaches to lower reaches in Daxin river basin, a typical karst area in the east of Ji’nan spring basin where the patterns of land use and human activity changes apparently.There is a close relationship between the groundwater and land use change and human activity.Therefore it is necessary to rearrange the patterns of land use and prevent the groundwater from polluting caused by unreasonable human activity in order to realize the sustainable utilization of karst water resources and to protect the famous spring-scape in Ji’nan.
