摘　　要：海河流域平原区作为本流域经济发展的重要区域,随着区域经济的飞速发展,对地下水资源的需求量越来越大,合理开发利用和保护地下水成了迫在眉睫的问题。本文根据海河流域平原区地下水的实际情况,选择地下水埋深、降雨入渗补给模数等7个能够反映地下水状况的指标建立地下水脆弱性评价指标体系,利用主成分-因子分析法获取相应的权重体系,及用综合指数法对海河流域平原区的地下水脆弱性进行评价,并用监测井实测的硝态氮浓度对评价结果进行检验,表明评价结果较为客观,能为该区域的地下水开发利用和保护提供有价值的参考依据。As the rapid economy development in Haihe basin, more amount of groundwater in plain area, of Haihe basin is needed. The rational exploitation and protection of groundwater become the pivotal problems According to actual conditions in Haihe basin, seven indexes like groundwater table, Infiltration in this area. modulus of precipitation etc, which can reflect the situation of groundwater are selected to construct the comprehensive indexes system. The weights of indexes are acquired by method of principal component-factor aalysis. The comprehensive index method is applied to assess the groundwater vulnerability in the study area. Observed data of nitrate concentration in well is used to check the assessment results. It is shown that these results are objective, the valuable information of decision-making support can be extracted for the exploitation and protection of groundwater.
