摘要
博山是山东省中部的一个工业城市,完全依靠地下水供水。主要的供水水源为中奥陶统碳酸盐类岩石中的裂隙-喀斯特水。城区附近的水源受到相当程度的污染。本文研究了主要的污染源及其污染途径,地下水中主要污染成分及其空间分布特征,用模糊数学方法进行地下水的水质评价,用地质统计学中的趋势面分析方法和Kriging方法模拟地下水中污染组分的空间分布,用灰色系统方法和对流弥散方程的特征有限元解进行地下水污染的预测。最后提出了博山地区地下水环境保护的建议。
Boshan is an industrial city in central Shandong Province. Groundwater is the unique source for the urban water supply. The main water source is fracture-karst water in Middle Ordovician carbonate rocks. This paper discusses the main pollution sources and the path of pollution, the main contaminants in groundwater and the characteristics of their spatial distribution and evaluation of groundwater quality with the fuzzy mathematic method. Geostatistical methods, such as the trend analysis and kriging methods, were used to simulate the distribution of contaminants in groundwater. The grey system method and characteristic finite element solution of the advective-dispersive equation were adopted to forecast pollution in the future. Finally some proposals for protection of groundwater environment in the Boshan area are put forward.
