Abstract: Based on the data of precise repeated leveling from 60’s to the late 80’s and by using the uniform adjustment calculating method, the uniform initial points and the same network. the maps of crustal vertical deformation rate (1965 to 1975, 1975 to 1979, 1979 to 1983, 1983 to 1988) have been produced in Tianjin and its adjacent areas. Combing with the geological and seismological background, the features of ground subsidence and the dynamic of its development in this area have been studied.The results obtained show that the main reasons for ground subsidence and for increase of coastal disasters are overpumping of underground water, especially in the tectonic sinking areas like TianJin and its adjacent areas. The funnels of ground subsidence distributed in TianJin and its adjacent areas have been developed to a very critical extent, and a series of secondary disasters associated with ground subsidence should take place in the near future. such as sea inundation and flooding with strom surges. the siltation of river channels and flooding involved. deterioration of hydrogeological canditions etc.
