The geological hazard of ground subsidence due to excessive exploitation of groundwater has been a limit to the sustainable development of economy in the plain area. This paper introduces an example of application of the InSAR technique to dynamic monitoring of ground subsidence in Mengcheng County,and assesses it from its incidence,probability and damage,initially building up a risk assessment index system. With this assessment system,the development trend and occurrence mechanism of the ground subsidence can be known well,the prevention and control zones can be divided,and risk control suggestions can be put forward for reducing the loss of people's lives and properties,and assuring the sustainable development of the society and economy in the area.
