摘　　要：利用第五至七次人口普查数据,探索基于土地利用类型的农业人口格网化方法,获得陕西省1.5 km农业人口格网密度数据,揭示农业人口分布的特征和时空演变过程。研究发现,2020年陕西省农业人口在关中平原和汉中盆地分布密集,陕北高原和秦巴山地相对稀疏;在河谷地带分布相对密集,而在城市核心区、难利用土地以及生态保护和水源涵养区密度极低。2000—2020年,陕西省农业人口密度全域普遍下降,但各地降幅存在差异,致使空间不均匀性加剧,其原因可能在于土地利用类型转变和农业人口规模下降速度不同。精度验证发现,农业人口格网数据与人口普查数据具有良好的一致性,农业人口格网数据集的拟合精度较高。研究减轻了可塑性面积单元问题,充分捕捉了农业人口分布的细节信息,对加快塑造分布合理的农业现代化人力资源、实现乡村全面振兴具有政策参考价值。The data from the fifth to seventh national censuses was used to explore a grid based method for agricultural population based on land use types,1.5 km of agricultural population grid density data in Shaanxi province was obtained to reveal the current characteristics and spatiotemporal evolution process of agricultural population distribution.Research found that in 2020,the agricultural population in Shaanxi province was densely distributed in the Guanzhong Plain and Hanzhong Basin,while the Northern Shaanxi Plateau and Qinba Mountains were relatively sparse.At the same time,the agricultural population is relative densely distributed in river valleys,while the density is extremely low in urban core areas,difficult to use land,and ecological protection and water conservation areas.From^(2)000 to 2020,the overall agricultural population density in Shaanxi province has generally decreased,but there are differences in the decline rates among different regions,leading to increased spatial heterogeneity.The reason may lie in the different changes in land use types and the slowdown in agricultural population size.The accuracy verification found that the agricultural population grid data has good consistency with[HJ1.8mm]the census data,and the fitting accuracy of the agricultural population grid dataset is relatively high.The research has alleviated the problem of plasticity area units,fully captured the detailed information of agricultural population distribution,and has policy reference value for accelerating the shaping of reasonably distributed modern agricultural human resources and achieving comprehensive rural revitalization.
