Determination of the groundwater potential (GWP) and groundwater pollution risk (GWPR) areas is a very important tool in the semi-arid regions in the world. Like many countries in the world, most of the major settlements in the cities of Turkey are located in permeable alluvial plains. Therefore, significant groundwater pollution is encountered in an alluvial plain containing settlements and industrial sites. This study focuses on the determination of the GWP and GWPR areas in the Alaşehir sub-basin, which is one of the economically important districts of the Aegean region, located in the Gediz River basin in western Turkey. In this study, the GWP and the GWPR areas were identified and a GWP index map was generated. The GWP areas in the study basin were determined using different proxies as a multi-criteria method based on geographic information system (GIS) integrated with remote sensing (RS). The result of the study indicates that the most GWP locations in the basin are seen in the west and southeast of the study region. Based on these results, it is understood that the significant GWP and GWPR areas are near the big settlement districts such as Alaşehir and Salihli. In particular, the 115-ha organized industrial zone located in the Salihli district is an important factor of the potential for consuming and contaminating water resources. This study method is so important for the selection of both city and industrial areas as well as for regional environmental planning in terms of the GWPR management.

使用多准则方法调查地下水潜力和地下水污染风险:一个案例研究(土耳其西部的阿拉谢希尔次流域)

在世界半干旱地区,确定地下水潜力(GWP)和地下水污染风险(GWPR)区域是非常重要的工具。像世界上许多国家一样,土耳其城市中的大多数主要定居点都位于可渗透的冲积平原上。因此,在包含居民点和工业用地的冲积平原上遇到了严重的地下水污染。这项研究的重点是确定阿拉谢希尔盆地的GWP和GWPR区域,该盆地是爱琴海地区的重要经济区之一,位于土耳其西部的盖迪兹河流域。在这项研究中,确定了全球升温潜能值和全球升温潜能值区域,并生成了全球升温潜能值指数图。该研究盆地的全球升温潜能值区域是使用不同的代理确定的,是一种基于集成了遥感(RS)的地理信息系统(GIS)的多准则方法。研究结果表明,盆地的全球升温潜能值最大的地区是研究区域的西部和东南部。根据这些结果,可以理解,重要的GWP和GWPR地区靠近诸如Alaşehir和Salihli的大定居区。尤其是,位于萨利赫里(Salihli)地区的115公顷有组织的工业区是潜在消耗和污染水资源的重要因素。对于GWPR管理而言,这种研究方法对于城市和工业区的选择以及区域环境规划都非常重要。研究结果表明,盆地的全球升温潜能值最大的地区是在研究区域的西部和东南部。根据这些结果,可以理解,重要的GWP和GWPR区域靠近诸如Alaşehir和Salihli的大定居区。特别是位于萨利赫里区的115公顷有组织的工业区是潜在消耗和污染水资源的重要因素。从GWPR管理的角度来看,这种研究方法对于城市和工业区的选择以及区域环境规划都非常重要。研究结果表明,盆地的全球升温潜能值最大的地区是在研究区域的西部和东南部。根据这些结果,可以理解,重要的GWP和GWPR区域靠近诸如Alaşehir和Salihli之类的大定居区。尤其是,位于萨利赫里(Salihli)地区的115公顷有组织的工业区是潜在消耗和污染水资源的重要因素。对于GWPR管理而言,这种研究方法对于城市和工业区的选择以及区域环境规划都非常重要。据了解,重要的全球升温潜能值(GWP)和全球升温潜能值(GWPR)区域靠近诸如阿拉谢希尔(Alaşehir)和萨利赫里(Salihli)之类的大定居区。尤其是,位于萨利赫里(Salihli)地区的115公顷有组织的工业区是潜在消耗和污染水资源的重要因素。对于GWPR管理而言,这种研究方法对于城市和工业区的选择以及区域环境规划都非常重要。据了解,重要的全球升温潜能值(GWP)和全球升温潜能值(GWPR)区域靠近诸如阿拉谢希尔(Alaşehir)和萨利赫里(Salihli)之类的大定居区。尤其是,位于萨利赫里(Salihli)地区的115公顷有组织的工业区是潜在消耗和污染水资源的重要因素。从GWPR管理的角度来看,这种研究方法对于城市和工业区的选择以及区域环境规划都非常重要。
