针对地面沉降与地下水水位变化的内在关系，考虑地面沉降受到自身变化规律的影响，建立基于库伊克变换的地面沉降预测模型，应用该模型对某地区地面沉降统计数据进行模拟预测，有效实现该地区地面沉降与地下水水位以及本身之间的定量模拟，并探讨模型的拟合效果和预测精度。结果表明库伊克模型拟合效果较好，预测精度较高，能较好地反映研究区域的地面沉降变形趋势。
針對地麵沉降與地下水水位變化的內在關繫，攷慮地麵沉降受到自身變化規律的影響，建立基于庫伊剋變換的地麵沉降預測模型，應用該模型對某地區地麵沉降統計數據進行模擬預測，有效實現該地區地麵沉降與地下水水位以及本身之間的定量模擬，併探討模型的擬閤效果和預測精度。結果錶明庫伊剋模型擬閤效果較好，預測精度較高，能較好地反映研究區域的地麵沉降變形趨勢。

According to the relationship between land subsidence and groundwater level ,and taking into account the impact from land subsidence itself ,this paper prosents a prediction model of land subsidence based on Koyck transform .The statistical data of a certain area are simulated and predicted ,on which the quantitative simulation of the relationship between land subsidence and groundwater level ,and itself is implemented efficiently . T he fitting effect and prediction accuracy of the model are discussed too .T he results show the Koyck model is well fitted and has higher prediction accuracy ,which can reflect well the trend of land subsidence .
