The ground subsidence of Xi'an city has caused many disasters in man's life.Therefore, it has been followed with more and more interest.This paper considers the developing of Xi'an ground subsidence as a grey procedure and the subsidence value as a grey variable.It also forecasts the developing tendency of the xi'an ground subsidence till the end of this century by using the GM(2,1) model-one of the theories of grey system. It can be seen through the counting results that by the end of this century Bafuzhuang, Chaganhuan 1, Hujiamao, Sapo and Caochangpo will continually speed up subsidence, that the rates of Hujiamiao and Sapo will be 210 mm/y, and that the Caochangpo's will be 100 mm/y.But, the rates of the Jinhua Hotel, the Xiaocai district, the Northwest Polytechical University and the Dao 370 will be decreased.Except that the subsidence speed of the Jinhua Hotel will be 78.8 mm/y, the other's will be decreased to 10~30 mm/y. Besides these, the paper also discusses the suitability for forecasting the ground subsidence of Xi'an city by using the GM(2,1) model.

西安市地面沉降已经对人们生活造成危害,因而日益受到人们的关注、本文将西安市地面沉降过程看作是一个灰色过程,地面沉降量被看作是一个灰变量,采用灰色系统理论中的GM(2,1)模型,对到本世纪末西安市地面沉降的发展趋势进行了预测。结果表明,到本世纪末,八府庄、长安环1、胡家庙、沙坡和草场坡将继续加速沉降,其中前二者的速率将达到350~360mm/y,胡家庙、沙坡的沉降速率将达到210mm/y,草场坡的沉降速率将达到100mm/y;金花饭店、小寨、西工大、导370的沉降速率将变慢,除金花饭店的沉降速率将降至78.8mm/y外,其余地点的沉降速率都将降下10~20mm/y。此外,还讨论了GM(2,1)模型对预测西安市地面沉降的适合性。
