摘要
海水入侵是世界许多沿海国家共同面临的一种海洋地质灾害。海水入侵危害严重,却容易被人们忽视,所以对海水入侵程度进行评价十分必要。以Cl-、M、SO42-、rHCO-3/rCl-及SAR五项化学特征指标作为评价因子,运用模糊数学的原理和方法,建立了海水入侵程度的模糊综合评判模型,将海水入侵程度分为四个等级。以烟台市永福园284号监测井点为例,根据其2006年水质监测资料进行了模糊综合评判。
Seawater intrusion is a geological hazard in many coastal country facing. Its influence is serious but neglected easily,so it is necessary to evaluating seawater intrusion. Five hydro-chemical indexes,including C1-,M,SO42-,r HCO-3/rCl-and SAR,are suggested to be impact factors. Based on fuzzy theory,the model of fuzzy c synthesized evaluation of seawater intrusion is established,and the seawater intrusion degree is divided into four ranking. Taking the 284 well in garden of Yong Fu of Yantai city as an example,according to its water quality data in 2006,this article gives a evaluation.
