摘　　要：通过对咸淡水界面水敏性的机理研究,表明盐浓度和水流速度变化引起多孔介质中微粒的膨胀,运移/沉积是导致咸-淡水界面渗透性变化的客观基础。另外,文章还综合论述了渗透性的变化在石油、岩土、环境和化学工程领域的应用及发展状况。指出咸淡水界面水敏性的研究对防止海水入侵具有重要的现实意义。The mechanism research on water sensitivity of saltwater- freshwater interface indicated that the swelling, migration and deposition of fines in porous media is the objective foundation caused the permeability change saltwater - freshwater interface. In addition, this paper summarized the application and development of permeability change at interface between saline water and fresh water in petrolic, geotechnical, environmental and chemical engineering. Especially the permeability change result from water sensitivity due to salinity change by the formation damage. It pointed out that the study of water sensitivity on the interface of saltwater - freshwater is worthy to prevent seawater intrusion.
