| Abstract: | The center zone of Shanghai city is selected as experimental zone so as to analyze synthetically the weight of every influence factor of land subsidence and establish the predictive model of land subsidence by using hierarchial analysis method.At the same time,fitting correlation analysis is carried out towards the major factor,i.e.ground water which affects related with land subsidence.It further proves that the depth of land subsidence is related to the rate of ground water pumping. |

| Keywords: | land subsidence analysis of hierarchy process correlation analysis analysis of cause model |
