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 karat area in the east of Jinan 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.

伴随土地利用方式的改变和人类活动强度的空间变化，地下水质从间接补给区、直接补给区到泉水排泄区，单项污染指数和综合污染指数依次升高；具有典型代表性的泉域东部大辛河流域，从上游、中游到下游，地下水污染物的浓度也渐次升高，且愈往下游污染物浓度增幅愈大，显示出与土地利用方式和人类活动的密切相关性。
