基于ArcGIS的大连地区地下水水质分布规律研究
The distribution pattern of groundwater quality in Dalian area based on ArcGIS
摘要
Abstract
To address the groundwater pollution degree and spatial distribution in Dalian,ArcGIS was used to study the spatial distribution pattern of water quality.The geostatistical analysis and spatial interpolation modules of ArcGIS were employed to analyze nine indicators in Dalian's groundwater,including pH,sulfate,and chloride.The results showed that pH exhibited the smallest spatial variation with little difference in spatial distribution,while chloride and sodium had higher coefficient of variation,indicating significant spatial heterogeneity.Further spatial interpolation analysis revealed the specific distribution of each indicator:for example,chloride had a higher concentration in the northern part of Lvshunkou District,and sodium ion concentration gradually increased from east to west.In terms of water quality evaluation,the single-factor evaluation method and comprehensive evaluation method were used to assess groundwater quality,finding that most of the water quality met Class Ⅲstandards.Spatial distribution analysis showed that water quality gradually declines from west to east,with relatively better water quality in Jinzhou District and poorer water quality in the central area and the north side of Lvshunkou District.关键词
