泉州湾海水入侵对城市发展建设影响

针对泉州湾存在海水入侵的问题,运用模糊综合评价法,建立适用的综合评价模型,得到较为准确的综合评价结果和海水入侵程度的分布图,并进一步分析海水入侵影响程度、波及范围及入侵方式.研究结果表明:该地区以轻度入侵为主,Ⅱ类水质地下水占比达到69.70%;受海水流向冲击的作用凸形海岸带相比凹形海岸带入侵程度更严重,最大入侵距离达到了1.50 km;其评价结果与实际现场相符.

Effect of Quanzhou Bay Seawater Intrusion on Urban Development and Construction

In order to solve the problem of seawater intrusion in Quanzhou Bay, it is necessary to establish the calibration of the invasion distribution. Fuzzy comprehensive evaluation method combined with sample measured data was used to build the suitable comprehensive evaluation model. The accurate evaluation results and the seawater intrusion degree distribution were obtained. The influence degree, the scope and the invasion of seawater intrusion were carried out, it’s showed that the region is mainly under mild invasion, the percentage of Ⅱ class groundwater is 69.70%; the invasion on convex coastal zone impacted by the water flow is more serious than the invasion on concave coast, the maximum invasion distance is 1.50 km; the evaluation results agree with the results in situ.
