摘　　要：文章以国土调查数据为基础,采用定量分析结合地类转移矩阵的方法,对比分析商洛市各县耕地资源现状和最近10年的变化情况。结果表明,商洛耕地占比仅7%,人均耕地不到1亩,且近10年间减少了超过1/3,耕地减少过快;各县情况存在差异,洛南耕地最多且减速较慢,柞水虽耕地最少但减速较慢,山阳、丹凤减速最快;各县耕地减少主要是因林地、种植园、城镇村、交通用地占用耕地过多,而草地新开发成的耕地较少。需加强耕地保护政策落实力度,严控耕地被占用,挖潜耕地后备资源,以扭转耕地资源严重流失的态势。Based on the national land survey data, the present situation of arable land resources and changes in the past ten years in each county of Shangluo were analyzed by using quantitative analysis combined with land transfer matrix.The results showed that:(1)arable lands only accounted for 7% of all the lands in Shangluo, and the area of arable lands per capita was less than 1 mu, which has decreased rapidly by more than 1/3 in the past ten years;(2)there are differences among counties, Luonan has the most arable lands and the area decreased slowly. Although Zhashui has the least arable lands, the area decreased slowly. The area of arable lands in Shanyang and Danfeng decreased the fastest;(3)the decrease of arable lands in each county was mainly due to the excessive occupation of arable lands by forest lands, plantations, town villages and traffic lands, while there was only a small area of newly developed grasslands.Therefore, it is necessary to strengthen the implementation of arable land protection policies, strictly control the occupation of arable lands, excavate potential arable land reserve resources, in order to reverse the serious loss of arable land resources.
