| 中文摘要:笔者以滹滏平原为研究区, 采用统计分析的方法, 分析了地下水防污性与地下水资源脆弱性随地下水位埋深之间的变化关系。结果表明, 当地下水位埋深增大时, 地下水防污性增强的地区, 地下水资源脆弱性也增高；通过二者之间变化关系, 认为受地下水位埋深制约及地下水位埋深对二者的不同影响, 存在使地下水系统脆弱性最佳的地下水位埋深区间；通过地下水位埋深对地下水防污性与地下水资源脆弱性影响及其制约关系, 确定滹滏平原淡水区和咸水区地下水系统脆弱性最佳地下水位埋深分别为27~30 m和15~19 m。 |

| Discussion on the Groundwater Depth of the Optimal Groundwater System Vulnerability in Hufu Plain |

| Abstract:The statistical analysis method was used to analyze the relationship between the aquifer sensitivity and the groundwater vulnerability with groundwater depth in Hufu plain. The result demonstrates that the vulnerability of groundwater resources increases and the aquifer sensitivity becomes stronger with the increasing groundwater depth. Based on an analysis of the relationship between the aquifer sensitivity and the groundwater vulnerability, the authors consider that the depth of groundwater is the key factor affecting groundwater resource vulnerability as well as aquifer sensitivity, and there exists a water table range of the optimal groundwater system vulnerability. The range is different in different areas. The water table range of the optimal groundwater vulnerability for fresh water and for saline water is defined at 27~30 m and 15~19 m respectively. |
