摘要

The groundwater along the coastal and valley areas of Jia-he has been intruded by seawater in the early 1980s. Base onrnthe series of monitoring data of the groundwater quality after 1985, which come from 11 typical well points, the seawater intrudingrndegree is interrelated generally with the dynamic variation of groundwater and is controlled mainly by the dropdown extent ofrngroundwater in the intruded area. In view of the characteristics of groundwater quality along Jia-he River valley, this paper evaluatesrnthe extent and behaviors of seawater intruding by the fuzzy comprehension evaluation according to vicissitudes of five hydro- hydrochemicalrnindexes including chemical Cl —, M, , SO SO4rn2—,rHCO HCO3/rCl and Cl SAR of three different periods (1994, 1999 and 2004). The evaluatingrnresults indicate that groundwater quality continues deteriorating following groundwater level declines year by year in the intrudedrnseverely areas where water level is in negative value, whereas intruded grade of groundwater is in a lower degree for long termrnoutside the areas.
