基于地理信息系统与综合分析法的海水淡化厂选址

随着沿海地区淡水资源日益短缺,海水淡化产业有着广阔的发展前景,海水淡化厂厂址的合理选择成为海水淡化应用研究的热点.以红石崖街区为例,通过分析海水淡化技术特点,确定了拟建海水淡化厂的淡化工艺;根据选址的空间要求,运用ArcGIS软件确定候选厂址,综合分析经济、海域水质、社会和政策因素,从候选厂址中选出最适宜建设海水淡化厂的地址.结果表明:该方法综合考虑多种因素,可直观得出海水淡化厂适宜厂址,具有一定的科学性和可操作性.

Location of Seawater Desalination Plant Based on GIS and Comprehensive Analysis

With the increasing shortage of fresh water resources in coastal areas, seawater desalination industry has a broad development prospect. How to select the suitable site of desalination plant has become a hot spot in seawater desalination applications. Taking Hongshiya street as an example, this paper determined the desalination process of the proposed desalination plant by analyzing the characteristics of seawater desalination technology. According to the spatial requirements of the site selection, the candidate plant site was determined by using ArcGIS software, and economic, Marine water quality, social and policy factors ware comprehensively analyzed to select the most suitable site from the candidate plant site. The result shows that this method can intuitively get the suitable plant site of the desalination plant considering various factors, and has certain scientificalness and operability.
