摘要
文章应用GIS软件及DRASTIC模型,选取黑龙江省某地级市进行了地下水污染现状评估、地下水污染荷载评估、地下水脆弱性评估、地下水功能价值评估及地下水污染风险防控分区。结果得出,地下水污染风险最高处位于研究区污染荷载较高的西北和西南部;中部和北部、南部的部分区域为中风险区域;其它为一般风险控制区域。研究成果为当地政府提出地下水污染防治对策和措施提供了理论依据。
Using GIS and DRASTIC model,this study conductsgroundwater pollution assessment,groundwater pollution load assessment,groundwater vulnerability assessment and groundwater function evaluation valuation. The risk of groundwater pollution prevention and control division from a city in Heilongjiang province was finished. The results show that the highest groundwater pollution risk is located in the northwest and southwest of the study area with higher pollution load; the middle,northern and southern parts are the middle risk regions. The research results provide a theoretical basis for the local government to propose countermeasures and measures for groundwater pollution control.
