| 摘要: |
| 为了解无锡市地下水水质状况，于2010年10—12月对无锡地区145口地下水井进行采样分析。以地理信息系统为技术手段，对不同土地利用类型和地下水类型的水污染物监测结果进行综合评价。结果表明，无锡全市地下水达标率为45.52%，整体水质情况处于“较好”级别；NH3-N、Mn和Fe为无锡市地下水的主要污染物；无锡市农业和建设用地区域地下水的污染程度整体要高于水体和林地区域；承压层的地下水污染较为严重。提出，无锡市管理部门应根据地下水污染现状，对地下水资源进行动态监测（包括水量和水质监测），并采取强有力的保护与治理措施，以实现区域水资源的持续利用。 |

| Abstract: |
| To learn more about the groundwater resources of Wuxi city, the groundwater from 145 wells in Wuxi was sampled and analyzed from Oct to Dec, 2010. The comprehensive analysis and evaluation on the results of water pollutants was accomplished based on different types of land use and ground water using Geographic Information System (GIS). The results showed that 45.52% of the groundwater samples met the quality standard, and the overall water quality was good. The main pollutants were NH3-N、Mn and Fe. Groundwater from agricultural land and from land for construction purposes had an overall higher degree of pollution than the entire water body as well as the water from forest regions in this city. Groundwater pollution was much more serious in the pressure bearing ground layer. Present situation of groundwater pollution urged the management department of Wuxi to conduct dynamic monitoring of groundwater resources (including water quantity and water quality monitoring), and to take strong protection and control for sustainable utilization of regional water resources. |
