摘　　要：通过定性与定量相结合,对比研究等分析方法研究宜君县近9年来耕地变化的主要因素及耕地变化驱动力。结果表明总人口、国民生产总值、二三产业增加值、固定资产投资是耕地变化的主要驱动力,利用回归分析方法预测宜君县今后一段时间内,在影响耕地的驱动力因子保持不变的情况下,耕地面积将持续减少,因此,为了宜君县的可持续发展,认为应该做好强化土地用途管制制度,建立耕地保护目标责任制,重视提高耕地质量的技术等措施。Through combination of qualitative and quantitative,the article studied the main factors of the cultivated land changing and the land-changed driving force of Yijun County area nearly nine years by application of the comparative analysis method.The results show that the total population,gross national product,two or three industrial added value,investment in fixed assets is the main driver of change in land-used regression analysis to predict Yijun County sometimes,the driving forces affecting arable land remain the same factor cases,the cultivated land area will continue to reduce,therefore,for sustainable development of Yijun County,which should strengthen the land-used control system,establish the responsibility system for farmland protection,the importance of improving the technical quality of arable land and other measures.
