苏州地面沉降灰色系统预测模型

On Establishment of Suzhou Earth Subsidence Gray Forecast Model

应用灰色系统理论，针对苏州市发生地面沉降的一组时间序列观测数据，建立了灰色预报ＧＭ（１，１）模型，预测了苏州市近期地面沉降量。计算结果表明，预测模型计算结果与实测值拟合较好。

This paper discusses the establishment of an earth subsidence gray model (1,1) to forecast the recent earth subsidence in Suzhou. In so doing, the gray theory and relevant data collected in time order with regards to Suzhou earth subsidence are used. The findings show that the result of the fray model forecast is in a good coincidence with the actual survey results.
