地下水水源地保护区划分方法研究综述

Summary of research on the method of partition of the groundwater wellhead protection zone

介绍国内外地下水水源地保护区划分方法的发展进程,重点剖析经验法、公式计算法、解析解模型法和数值模拟法的特点及适用条件。鉴于目前国际上流行的数值模拟方法中具有不确定性特征的水文地质参数是影响保护区划分的重要因素,强调了条件随机模拟思想对保护区划分的重要性,指出了地下水水源地保护区划分的发展趋势和研究方向。

The development process of the method of partition of the grotmdwater wellhead protection zone is introduced. The characteristics and applicable condition of the empirical method, formulation calculation method, analytical model algorithm and numerical simulation method are anatomized. In the international popular numerical simulation method, the hydro-geological parameters with uncertain characteristics are important factors affecting the protection zone delineation, which emphasizes the importance of stochastic simulafion in the protection zone delineation. Finally, the development and the research direction of the partition of the groundwater wellhead protection zone are described.
