华北平原典型地区地下水污染防治区划探讨

The division of groundwater pollution control in North China Plain

地下水是华北平原重要饮用水水源和战略资源。随着经济社会的快速发展,部分城市和工业企业周边地下水污染呈恶化趋势。以河北某市作为开展华北平原地下水污染防治区划研究的典型地区,基于地理信息系统(GIS)平台,采用地下水污染源荷载、地下水脆弱性、地下水功能价值评价和地下水污染现状评估结果,将研究区划分为保护区、防控区和治理区,面积分别为577.4、1 459.2、10.5km2,为该区域地下水环境保护工作提供重要参考。

Groundwater is an important source and strategic resources of drinking water in North China Plain. With the rapid economic and social development, the groundwater pollution in the surrounding of some cities and in- dustrial enterprises is more and more serious. The studies of groundwater pollution prevention division had been car- ried out in a city of Hebei. On GIS-based platform, using groundwater pollution load evaluation, vulnerability assess- ment, function evaluation and groundwater pollution status assessment results, the study area was divided into protec- ted areas, treatment areas and the prevention and control area. The protective area was 577.4 km2 , the prevention area was 1 459.2 km2 ,the treatment area was 10.5 km2. That provided an important reference for the regional groundwater environmental protection.
