以農業部自2018年至2021年各縣市農地資源盤點，共80個農地盤點表格，經彙整後建立全台及各縣市資料視覺化圖表，試圖找出農地資源變動及變化異常原因。研究結果在「可供糧食生產」面積這四年間呈增加現象，在「實際供農林漁牧休閒使用」面積，自2018年起有逐年呈增加趨勢；至於「農業及農地資源」面積在四年間仍呈微幅變動，但整體來看並不明顯。分析農地面積減少關鍵因素，透過AI檢視資料，得到「違法非農業使用」（如農舍、住宅及疑似工廠等）和「容許非農業使用」（如道路或設施等使用）為農地減少的關鍵因素，呈正向現象；但深入分析包括住宅、疑似工廠及宗教寺廟、以及河川或水利設施增加等使用類型面積仍出現增加趨勢。從縣市別來探討關鍵因素，有基隆市、台北市、金門縣及澎湖縣等，四年平均農地使用面積比其它縣市平均面積減少。

Based on the inventory of farmland resources in various counties and cities from 2018 to 2021 by the Ministry of Agriculture, a total of 88 farmland inventory tables, and after consolidation, a visual chart of the whole of Taiwan and county and city data was established to try to find out the changes in farmland resources and the reasons for abnormal changes. The results showed that "food production" increased in the past four years, and the area "actually used for agriculture, forestry, fishery, animal husbandry, and leisure" increased year by year since 2018. As for agriculture and the area of agricultural land resources, there has been a slight change in the past four years, but the overall view is not apparent. Analyzing the critical factors of farmland area reduction, AI review data shows that "illegal non-agricultural use" (e.g., farmhouses, dwellings, and suspected factories, etc.) and "permissible nonagricultural use" (e.g., use of roads or facilities) are the critical factors in the reduction of farmland, which are positive. However, in-depth analysis includes an increase in the area of residential buildings, suspected factories, and religious temples, and the increase in rivers or water conservancy facilities. Critical factors in terms of counties and cities, such as Keelung City, Taipei City, Kinmen County, and Penghu County, have reduced the average area of agricultural land use in four years compared with the middle area of other counties and cities.
