| 中文摘要: |
| 随着工业化和城市化进程的加快,黄山市中心城区浅层地下水多数受到了不同程度的污染。本文选取了地下水位埋深、净补给量、含水层渗透系数、地形坡度、含水层介质、土壤介质及非饱和带介质7个指标,用层次分析法确定权重,建立了黄山市中心城区地下水易污性评价DRASTIC指标体系。借助于Mapgis技术的空间分析及制图功能,对该地区浅层地下水防污性能进行了评价和分区。评价结果与实测区域地下水质量较好的吻合,说明基于DRASTIC模型的浅层地下水防污性能相关成果在一定程度上可为该地区政府管理部门制定城市规划、工业布局和地下水资源保护提供决策参考。 |
| 英文摘要: |
| With the rapid process of industrialization and urbanization, shallow groundwater in the central zone of Huangshan City has been contaminated by different degrees. In this study, depth to water, recharge of precipitation, aquifer hydraulic conductivity, topography, aquifer media, soil media and impact of vadose zone were chosen as indexes and the corresponding weight was calculated to establish DRASTIC model for groundwater antipollution assessment of the area. Based on powerful spatial analysis and mapping function of Mapgis technology, quantitative assessment and division were performed for the antipollution of the shallow groundwater in the area. The results of the evaluation are in good agreement with the measured groundwater quality in the area, which indicates that the antipollution distribution map of the shallow groundwater can be a reference for decision-making of urban planning, industrial layout and groundwater resources protection for government management of this area. |
