泉州市沿海地区地下水水质评价与时空差异分析研究

采用单项组分评价和综合评价法对泉州市沿海地区地下水质量进行综合评价,在对区域丰、枯水期地下水污染超标项目以及地下水质量级别分布进行分析比较的基础上,通过构建综合评价得分统计指标对区域地下水质量的时空差异进行分析,最后对影响区域地下水水质分布格局的人口、经济等相关因素进行相关性分析.研究结果表明,泉州市沿海地区地下水质量状况总体一般,区际差异比较明显,其中丰水期较好、枯水期较差,区域地下水质量的空间分布格局与地方人口分布及经济状况密切相关.

Groundwater Quality Evaluation and Its Timeand Space Differences in Coastal Areas of Quanzhou

With the methods of individual components and comprehensive evaluation, the groundwater quality is evaluated comprehensively in coastal areas of Quanzhou.The excessive projects of groundwater polluting and the distribution of groundwater quality level are analyzed comparatively between high flow period and low water period.By constructing statistics indexes of comprehensive evaluation score, the differences of space and time of regional groundwater quality are analyzed.Finally, the related factors of population and economic are correlatively analyzed, which influence the distribution pattern of regional groundwater quality.The research results show that the groundwater quality is normal overall in coastal areas of Quanzhou, and the interregional differences is obvious.The groundwater quality is better in high flow period and poor in low water period.The spatial distribution pattern of regional groundwater quality is closely related to the local population distribution and economic conditions.
