岸线变化对钦州湾污染物输移扩散的影响
Impact of Shoreline Changes on the Pollutant Transport and Dispersion in Qinzhou Bay
摘要
Abstract
[Objective]To analyze the effect of shoreline changes on pollutant transport and dispersion can provide scientific basis for exploitation of coastline and marine environmental protection in Qinzhou Bay.[Methods]Based on the change of shoreline from 2004 to 2012,the MIKE21 mathematical model was used to simulate the COD dispersion in Qinzhou Bay.[Results] The COD dispersion area in low tide was greater than that in high tide,and in neap tide the COD dispersion area is larger than that in spring tide.The change of shoreline had a certain impact on the pollutant transport and dispersion in Qinzhou Bay,the dispersion area of COD in Jinguliang estuary was slightly larger than that before the change of shoreline,and the area where COD concentration increased more than 2 mg/L between Sandun road and Xiniujiao was significantly greater than that before the change of shoreline.[Conclusion]Rational exploitation and utilization of shoreline is of great significance to improve the transport and dispersion of pollutants in Qinzhou Bay and protect the marine environment.关键词
