摘要(中) 地層下陷是一種不可逆的地理現象,世界各地發生的地層下陷已經嚴重影響了人身安全,而台灣也不例外,所以預測地層下陷並做到提前防治下陷成為目前重要的議題。在早期台灣地層下陷預測較著重在數值研究模擬,相較於數值模擬,人工智慧方法不需提供推估的水文參數和抽水量資料,可以直接透過給定的資料集進行建模,而其他應用人工智慧方式預測的研究也礙於紀錄資料不夠充足無法做到有效的預測,隨著紀錄資料越來越豐富和人工智慧技術越發進步,在此議題上更能夠取得不錯的效果。本研究使用克利金插值法(Kriging Interpolation)對 Global Navigation Satellite System(GNSS)自動固定站資料建立雲林縣全域的資料集和以測站為單位的資料集,分別測試雲林縣全域地層下陷敏感性模型對地層下陷的描述能力和預測數座需要特別關注的 GNSS 測站未來數周地層下陷量以每彌補測站測量資料時所需的時間延遲。在使用了七種特徵建立模型 – 地下水水位、濕度、氣溫、降雨量、日照時數、土地利用、地質組成,在雲林縣全域地層下陷敏感性測試中已經可建立有效描述真實下陷量的模型,指標中 R2

impact on human safety around the world, and Taiwan is no exception. Therefore,
predicting land subsidence and implementing early prevention measures have become
important issues. In the early stages, land subsidence prediction in Taiwan focused
mainly on numerical research and simulations. Compared to numerical simulations,
artificial intelligence methods do not require estimated hydrological parameters and
pumping data. They can directly model the given dataset. However, other studies that
apply artificial intelligence methods for prediction have been hindered by insufficient
recorded data, making it challenging to achieve effective predictions. With the
increasing availability of recorded data and advancements in artificial intelligence
technology, more promising results can be achieved in this field. This study utilized
the Kriging interpolation to establish a dataset for the entire Yunlin County using
Global Navigation Satellite System (GNSS) automatic reference station data, as well
as station-based datasets. This study utilized the Kriging method to establish a dataset
for the entire Yunlin County using Global Navigation Satellite System (GNSS)
automatic reference station data, as well as station-based datasets. By using seven
features, including groundwater level, humidity, temperature, rainfall, sunshine hours,
land use, and geological composition, the model was able to effectively describe the
real subsidence levels in the Yunlin County-wide land subsidence sensitivity test. The
evaluation indicators were as follows: R
2
(Coefficient of Determination) – 0.954, Cor
(Pearson Correlation Coefficient) – 0.979, MSE (Mean Square Error) – 2.20E-05 (unit:
square meter). Regarding the prediction of specific GNSS stations, the model showed
the most stable results when using an 8-week training dataset to predict subsidence for
the next 8 weeks. The combined model yielded the following results: R2 – 0.221, Cor– 0.519, and RMSE (Root Mean Square Error) – 0.00207(unit: meter).關鍵字(中) ★ 地層下陷預測
