Abstract:: In order to scientifically understand the spatial and temporal evolution of agricultural space in Jianghan Plain, and provide a basis for rational development and utilization of agricultural space and promote the adjustment of agricultural development structure, based on 30 m resolution land use data in 2010, 2015 and 2020, we applied land-use transfer matrix and hotspot analysis to study the evolution characteristics of agricultural space in Jianghan Plain from the spatial-temporal dimension, and then used geographic detector model to analyze main driving mechanism of agricultural space change from 2010 to 2020. The results show that:(1)agricultural space decreased 447.41 km² between 2010 to 2020 in Jianghan Plain, and it accounted for 82.62% of total land in 2020; the area of cultivated land decreased continuously while the area of rural construction land increased rapidly;(2)agricultural space was mainly transformed into urban space(391.68 km² and accounting for the 67.23% of the transferred agricultural space);(3)the transfer-out mainly distributed in Caidian, Hanchuan, Jingzhou, and Shashi, while the transfer-into mainly distributed in Jingshan, Dangyang, Honghu;(4)the explanatory ability of driving factors varied in different periods, but policy factors, output value of primary industry, rural population and elevation were the driving factors with strong explanatory ability, and the interaction detection results were mainly nonlinear enhancement. In conclusion, driven by various factors, the area of agricultural space in Jianghan Plain had been decreasing from 2010 to 2020, and it concentrated near the central urban area. Therefore, the decreasing trend should be appropriately adjusted.
