摘要
滦河下游灌区是濒临渤海的灌区。随着近年来灌区地下水资源的开发利用,海水入侵问题日显突出,对环境造成诸多不利影响。本文运用模糊数学的基本思想方法,以水文地质条件为背景并结合已有地下水水质资料,根据海水入侵地下水水质的特点,选择Cl-、M、SAR、SO42-4项化学指标作为评价指标,将侵染程度划分为4级,根据模糊数学最大隶属度原则,构造了综合评价模糊数学模型,应用所建模型对海水入侵进行综合评价。评价结果表明,灌区受海水侵染程度不断恶化,入侵严重地区地下水水质达到Ⅳ级。研究成果对于滦河下游灌区水资源合理开发利用具有十分重要的参考价值。
Luan River Irrigation District is bordering the Bohai Sea.With the utilization of underground water resources in recent years,Seawater intrusion deteriorated continuously,which caused adverse impacts on the environment.Based on the basic idea of the fuzzy mathematics and the local hydrogeological conditions,Using measured groundwater quality data,and considering the features of seawater intrusion,the Cl-,M,SAR,SO2-4were selected as evaluation indicators.The degree of seawater intrusion was classified into four grades.According to the principles of fuzzy mathematics maximum subjection degree,fuzzy mathematical comprehensive evaluation model was set up.The model was used to make comprehensive evaluation on sea water intrusion.It is shown through evaluation that the underground water pollution by sea water deteriorated continuously.The most serious pollution reached Ⅳ grade.it is sure that the present research findings should play very important reference value in reasonable water resources development in the Luan River Irrigation Area.
