摘　　要：利用国家863课题支持研制的电阻率探杆自动监测系统,分别进行了海水入侵、地下水位升降、土壤盐渍化过程的动态监测室内模拟实验,旨在探讨该系统用于海水入侵、地下水位变化、土壤盐渍化等环境过程自动监测的可行性。结果表明,海水入侵形成的咸-淡水界面及海水弥散带,地下水位位置上下及包气带,及不同含盐量的土体,均具有显著的电阻率探杆测试结果特征差异。该系统可为海水入侵,地下水位变化,土壤盐渍化,土壤地下污染等环境过程的原位连续实时自动监测提供数据资料及技术支持。In order to verify the availability of the monitoring system in monitoring the environmental processes such as seawater intrusion,groundwater level change and soil salinization,the dynamic monitoring simulation experiments had been carried on seawater intrusion,groundwater level rising and falling,and soil salinization respectively using self-made automatic monitoring system supported by National 863 Topics with resistivity.The results showed that the saltwater-freshwater interface and the dispersion zone by seawater intrusion,the position above or below the groundwater level and the unsaturated zone,and soils with different salt contents had significant resistivity differences in test results.It could provide data and technique support for environmental processes such as seawater intrusion,groundwater level changes,soil salinization and underground contamination.
