详细介绍了地下水水源保护区范围的计算方法:Krijgsman-Lobo-Ferreira(KLF)法,分别推导出了正水流梯度方向、负水流梯度方向和垂直于地下水流方向保护区范围的计算公式,并就方法的适用性及参数取值等问题进行了探讨。在徐州张集地区应用的结果表明,KLF法提供了一种计算地下水保护区范围的便捷、科学、有效的方法,计算结果对于确定地下水源保护区范围及有效保护地下水源具有实际意义。
The Krijgsman-Lobo-Ferreira (KLF) method is introduced in detail to calculate the range of the groundwater source protection area, and the formulas of the positive water flow gradient direction, the negative water flow gradient direction and the vertical protection area of the groundwater flow direction are derived respectively The applicability of the method and the parameter values and other issues were discussed. The results of the application in Zhangji district of Xuzhou show that the KLF method provides a convenient, scientific and effective method for calculating the scope of groundwater protection areas. The calculation results have practical significance for determining the scope of groundwater source protection areas and effectively protecting groundwater sources.
