The study aims to reveal the transition features of agricultural land use in the Groundnut Basin of Senegal from 2009 to 2018, especially the impact of urbanization on agricultural land and the viewpoint of farmland spatiotemporal evolution. Integrated data of time series MCD12Q1 land-use images of 2009, 2012, 2015, and 2018 were used to provide a land transition in agricultural and urban areas through the synergistic methodology. Socio-economic data was also used to serve as a basis for the argument. The results highlight that: (1) Agricultural land increased by 14.53%, with a dynamic index of 1.45 from 2009–2018. (2) Over the same period, urbanization increased by 2.80%, with a dynamic index of 0.28. (3) In different regions, the transition of agricultural land in Kaffrine is most intense (expansion rate: 22.80%). The same situation of urbanization happened in Thiès Region with a value of 7.94%. Except for Thiès, agricultural land in other regions has not yet been subject to major pressure due to urbanization. Overall, the farming system in Groundnut Basin is an extensive model, the recommendations from the point of view of land-use planning and land law are necessary to ensure efficient agricultural land management in the area.

塞内加尔“花生盆地”的农业用地转型：2009 年至 2018 年

研究旨在揭示2009-2018年塞内加尔花生盆地农地利用的转变特征，尤其是城市化对农用地的影响和耕地时空演变的观点。2009年、2012年、2015年和2018年时间序列MCD12Q1土地利用图像的综合数据被用来通过协同方法提供农业和城市地区的土地转型。社会经济数据也被用作论证的基础。结果表明：（1）2009-2018年农用地增长14.53%，动态指数为1.45。（2）同期，城镇化增长2.80%，动态指数为0.28。(3)在不同地区，卡夫林农用地的转型最为强烈（扩张率：22.80%）。同样的城市化情况发生在捷斯地区，值为 7.94%。除蒂耶斯外，其他地区的农用地尚未因城市化而受到较大压力。总体而言，花生流域的耕作制度是一种粗放型模式，从土地利用规划和土地法的角度提出建议对于确保该地区农地的有效管理是必要的。
