龙门港镇海水入侵三维数值模拟研究
Journal: Ecological Environment and Protection DOI: 10.12238/eep.v4i4.1418
Abstract
龙门港镇是广西壮族自治区钦州市的一个港口镇,地下水是岛上居民生活和工农业生产用水的重要水源。由于长期不合理开采,已经出现海水入侵问题,对龙门港镇居民生活和生产造成了影响。为此,本文在实地调查和收集整理分析相关资料的基础上,基于溶质运移相关理论,采用有限元数值模拟方法,利用COMSOL Multiphyscis软件建立了龙门港镇海水入侵数值模型,对龙门港镇1000天以内海水入侵发展趋势进行了预测。结果表明,龙门港镇局部出现了海水入侵现象。为防止龙门港镇地区海水入侵进一步恶化,建议进一步完善地下水动态监测网,采取有效措施防止海水入侵进一步发展。
