中文摘要:
      明确不同地区地下水污染的组分和成因,可为针对性的制定地下水资源管理制度、改善水质提供保障。由于城区和郊县经济发展水平和地下水资源开发利用模式差别较大,水污染程度和污染组分可能存在较大差异。本文以郑州市的金水区和巩义为例,运用主成分分析法对两者地下水污染状况进行评价。结果表明:巩义市地下水主要污染组分以硝酸盐等有机污染物为主,金水区以硫酸盐、氨氮等有机污染物为主。造成这种现象的主要原因是巩义市工矿企业、农田较多,金水区农田、工矿企业较少而生活污水排放比重较大。根据两个地区不同的地下水污染状况和成因,就地下水资源保护和管理提出了针对性的建议。
英文摘要:
      To clarify the components and causes of groundwater pollution in different areas can provide guarantee for formulating groundwater resource management system and improving water quality. Because the economic development level and groundwater resources development and utilization mode of urban and suburban areas are quite different, the degree of water pollution and pollution components may be quite different. Taking Jinshui District and Gongyi county of Zhengzhou City as examples, this paper evaluates the groundwater pollution of the two areas by principal component analysis.The results show that nitrate and other organic pollutants are the main components of groundwater pollution in Gongyi, while sulfate and ammonia nitrogen are the main organic pollutants in Jinshui District. The main reason for this phenomenon is that there are more industrial and mining enterprises and farmland in Gongyi, less farmland and industrial and mining enterprises in Jinshui District and a larger proportion of domestic sewage discharge. According to the different groundwater pollution conditions and causes in the two areas, this paper puts forward some pertinent suggestions on the protection and management of groundwater resources.
