摘　　要：由于地下水监测受到实际条件的限制,人们在对其进行观测时只能获取有限的监测结果。Kriging作为一种地统计插值方法,可以有效表征离散的点状信息向面状连续信息的转换。以福建省晋江地区地下水氯离子指标为样品数据,研究普通Kriging插值法的相关参数设置和最优半方差模型选择,确定符合实际情况的普通Kriging插值结果。结果表明:该地区地下水氯离子指标存在着中等程度空间自相关,经几何间距重分成5类后得到空间分布图,可帮助环境管理者在有限的时间和资源下确定地下水资源的风险性并加以防范。As the groundwater monitoring by the actual conditions, people can only get them a limited observation monitoring results. Kriging as an effective geo-statistical interpolation method, the method can continuous express discrete point data to plane data information convert, take the chloride ion of groundwater sample data in Jinjiang as an example to research ordinary Kriging interpolation method and the optimal parameter settings related to semi-variance model selection to determine realistic ordinary Kriging interpolation results . The results showed that： the area of groundwater chloride ion indicators exist moderate spatial autocorrelation, the geometric spacing obtained after re-divided into five classes spatial dis- tribution map for environmental managers in the limited time and resources to determine the risk of groundwater resources and make prevention.
