摘要
以湖北省宜昌市当阳市2000、2010、2020年3期的土地利用数据为基础,选取自然、经济、社会等13个因子作为影响耕地变化的驱动因子,利用土地利用转移矩阵以及核密度分析,引入耕地利用动态度模型,结合地理探测器方法,探究2000—2020年当阳市各镇耕地的时空变化特征以及主要驱动因素。结果表明,耕地分布总体上呈现由东南向西北递减的趋势,2010—2020年当阳市耕地变化较显著,耕地面积减小。经济社会因素是影响耕地分布的主要因子,但与其他因子交互时,对耕地的影响减弱,自然因子对耕地影响存在交互作用。
Based on the land use data of Dangyang City,Yichang City,Hubei Province in 2000,2010 and 2020,13 factors such as nature,economy and society were selected as the driving factors affecting the change of cultivated land. Using the land use transition matrix and the kernel density analysis,the dynamic degree model of cultivated land use was introduced,combined with the geographic detector method,to explore the spatiotemporal variation characteristics and main driving factors of cultivated land in various towns in Dangyang City from 2000 to 2020. The results showed that the distribution of cultivated land generally showed a decreasing trend from southeast to northwest. From 2010 to 2020,the cultivated land in Dangyang City changed significantly,and the cultivated land area decreased. Economic and social factors are the main factors affecting the distribution of cultivated land,but when interacting with other factors,the impact on cultivated land is weakened,and natural factors have interactive effects on cultivated land.
