Impact Study Of The Marine Environment Of The Dumping Area Of30Million Tons Of Curde Oil Terminal Project In Rizhao Port

Rizhao city is located at118°35′~119°35′E,35°04′~36°02′N, in the middle ofChina’s coast areas, the south wing of Shandong Peninsula,west China’s Beijing-Shanghailine, along the Eurasian Continental Bridgezone to the sea, has a unique geographicaladvantage and the Betterment of harbor conditions.Rizhao300000tons of crude oilterminal Project by Rizhao Port Co,.Ltd. involving berths and roundabout water dredgingproject, dredging volume of1042.9×104m3. Based on the "reduction andresource"principle, of which529.9×104m3of dredged material used for reclamation, butthere are still450×104m3need outside throw to a temporary ocean dumping.In order to ensure the dock project carried out smoothly and to protect the marineenvironment and marine resources, the preservation of the marine ecological balance, thisarticle intends to adopt historical background investigations, site environmentalinvestigation, experimental analysis and testing and environmental numerical simulationforecast a variety of methods of combining the technical route, waters of environmentalQuality survey and Evaluation of the tidal current field and the dredged material onnumerical simulation analysis, the dumping of dredged material on the marineenvironment impact prediction and assessment, conducted a comprehensive evaluationand research, choose a smaller impact on the marine environment regionalas a dumpingarea.In the dumping site of election planning process, we give full consideration to apreselected area, around sensitive targets, the preselected area, with the marine functionzoning compliance, the preselected area, the surrounding marine environment, the statusquo, the surrounding ecology losses caused by the suspended sediment diffusion,suspended sand deposition on the sediment and water depth, suspend sediment migrationof seabed scour, throw the mud generated by the economic costs and other aspects, tofinalize the119°38′55″E,35°11′N of a circle, the radius of1km round as a dumping area.
