环渤海地区海(咸)水入侵特征与防治对策

本文中阐述了环渤海沿海地区海（成）水入侵的主要方式、发展进程、影响因素等基本特征，提出海（成）水入侵的综合防治对策。研究区海（成）水入侵主要有面状、带状、脉状或树枝状和越流等4种入侵方式。气候、地形地貌、地质与水文地质是发生海（成）水入侵的基础条件，地下水超采等人类不合理工程经济活动是诱发海（成）水入侵的主要原因。通过调整产业结构、建立节水型社会体系，合理规划利用水土资源，建造阻成蓄淡工程，跨流域引水，以及建立健全监测预警系统等综合措施，防止海（成）水入侵的发展。

Character and Prevention Strategies of Sea (Saline) Water Invasion in Circum-Bohai-Sea Region

The basic character,the main manner,process of development and influencing factor of sea(saline)water intrusion are explained in this paper.General prevention strategies of sea(saline) water intrusion are presented.There are four manners of sea(saline) water intrusion including plane,zonal,nervation or arborization and leaky of groundwater in study area.Foundation condition of arising sea(saline) water invasion are climate,landform,geology and hydrological geology factor.Main reasons of placing a premium on sea(saline) water invasion are irrational human engineering and economic activities,for example,over-mining of ground water and so on.To prevent the development of sea(saline) water intrusion,we need adjust industrial structure,build a water-saving society system use natural environment rationally,create the project of stopping seawater intrusion and storing fresh groundwater,transfer water across valley and construct monitoring system.
