| Abstract: | Marine invasion is a kind of geologic hazard co made by nature and mankind Since 70's, marine invasion in Liaoning Province have gotten more heavily with the invasion area wider and the speed of invasion higher At prsent,marine invasion in Liaoning province has cause heavily hazard to the production of industry and agriculature, and to the people's living Marine invasion in Liaoning Province is mainly caused by lithological characteristics, texture, thickness, permeability of aquifers, the closely hydraulic relationship between undergraoud water and sea water, Neotectonic movements and paleoclimatic changes since Quaternary, and manmade overexploitation Based on the studies on the distribution and hazard degrees of marine invasion in Liaoning Province, it is proposed to take some controlling measure, such as, to controll the exploiration of undergraound water near the sea, to inject fresh water into aquifers, to dig intercepting wells and then to withdrawal the sea water, to construct a groundwater reservoir, etc |
