研究采用单一指标法分析大连市地下水质状况，通过RS、GIS技术和土地利用动态度分析2000-2009年大连市甘井子区土地利用变化，得到海水入侵对滨海城市化发展影响的时空分布特征，建立海水入侵与滨海城市化耦合关系，为滨海城市可持续发展提供决策支持．结果表明：（1）1978-2010年间，大连市海水入侵面积大致呈上升趋势，其中2007、2008、2009年度达到最大值（867．8 km2）；（2）海水入侵对城市化的影响：海水入侵对城市化的发展产生负向作用，减缓城市化的进程．海水入侵使得地下水质污染严重，危害生活城市化的进程．海水入侵使得土地利用发生变化，使得空间城市进程受阻；（3）城市化对海水入侵的影响：城市化对海水入侵起到促进作用．由于工农业用水的需要、城市建设以及海水养殖，对地下水的过度开采使得海水入侵程度增强．

The single index method was used to analyze the current situation of the underground water quality in dalian .The changes of land use from 2000 to 2009 were analyzed based on land use dynam-ics model ,which were supported by RS ,GIS technology .By doing these ,we can get seawater intru-sion in coastal urbanization affect spatial and temporal distribution ,establish the coupled relation-ships of saltwater intrusion and coastal urbanization ,provide decision support for the sustainable de-velopment of the coastal city .The results showed that :(1)From 1978 to 2010 ,the area of seawater intrusion in dalian was generally rising ,in 2007 ,2008 ,2009 reaching maximum (867 .8 km2 );(2)Seawater intrusion impacted on urbanization :seawater intrusion of urbanization has a negative effect ,slowing the process of urbanization .Seawater intrusion made the quality of ground water seri-ously pollute and endangered life of urbanization process ;seawater intrusion made land -use changes and frustrated process of urban space ;(3)The urbanization impacted on seawater intrusion :urbaniza-tion to promote seawater intrusion .As a result of the need of agricultural water ,urban construction and mariculture ,overexploitation of groundwater makes the degree seawater intrusion increase .
