Quantitative suitability evaluation and spatial zoning for seawater desalination water intake site selection

Seawater desalination water intake site selection has an important impact on the investment, production cost, stable operation, and safety of seawater plants. Site is affected by many factors, such as natural geography, ecological environment, social economy coastal zones; some constraints can be directly identified unsuitable areas for these construction projects. For shallow method desalination, this study selects suitability evaluation indicators from three influencing factors basic industrial development constructs a model based multifactor spatial overlay analysis Geographic Information System platform. This carries out quantitative realizes suitable zoning spatially selecting intake, thus forming scientific, quantitative, system process. The was applied in Rongcheng city offshore area China analyzed. results showed that comprised 304.8 square kilometers, which were mainly distributed northern near coastline its central southern regions. covered 292.4 marine red line aquaculture city. met needs project improves upon existing at theoretical technical levels provides scientific basis location planning large ranges waters.
