| 摘 要： | 特殊脆弱性分析评价是实现定量研究地下水受某种特定污染物威胁的有效手段。文章以佳木斯市七水源地为研究对象，在分析区域水文地质条件的基础上，选取地下水防污性能评价模型（DRASTIC）用于研究区固有脆弱性的评价，侧重分析区内土地利用类型、稳定开采条件下的地下水水位降深等人为因素，以及典型污染物氨氮在特定介质中的通量这一特殊人类活动因素，构建了水源地特殊脆弱性评价模型。以研究区内28组浅层地下水样品中氨氮浓度和对应采样点特殊脆弱性指数之间的相关性来评估模型的可靠性，计算结果显示二者相关系数为0.67，具有较好的相关性，说明该评价系统可靠。特殊脆弱性计算结果显示研究区内以中等以下脆弱性为主，其中水源开采区和西南丘陵区特殊脆弱性较高，计算结果有助于实现水源地的科学管理。

| Abstract: | The special vulnerability assessment is an effective means for quantitatively evaluating the groundwater contamination resulted from some special pollutants. Based on the hydrogeological analysis of the Qi Water Source Area in Jiamusi City, China, the DRASTIC model was selected to calculate the inherent vulnerability. The calculation mainly focused on investigating the impact of human factors, including different land use types, depression of the groundwater level in stable exploitation conditions, and the flux of the typical pollutant, i.e. ammonia nitrogen, in specific mediums. The special vulnerability of regional groundwater assessment index system was accordingly built and used for assessing the study area. The results has been verified by the correlation analysis between the observed concentration of ammonia from 28 shallow groundwater samples in the study area and the calculated special vulnerability at corresponding points,which indicate that the special vulnerability assessment system is reliable. The results show that the vulnerability of the regional groundwater is mostly at a moderate and low level, while the high level appears in the exploitation area and the southwest upland. This study is helpful for the scientific management of drinking water source areas. |
