摘　　要：分析了延安城市化进程和耕地资源的变化趋势以及两者之间的相关关系,结果得出:延安市的城市化进程经历了快速增长、波动、徘徊停滞、稳步上升4个时期;耕地面积变化总体上呈减少趋势,与全省的耕地面积变化基本一致;耕地面积减少量与城市化水平呈现出非典型的“U”型曲线形状。延安城市化进程中必须不断提高城市土地的集约利用程度,变外延扩张为内涵发展,同时要加强耕地保护。图4,参19。Urbanization, cultivated land changes and their relationship in yan＇an city were analyzed in the paper. The study results show that the urbanization in Yan＇an city generally experienced four periods which are rapid growth,fluctuation,stagnation and steadily rising. Cultivated Land reduced gradually like Shaanxi province. The reduced amount of arable land and the level of urbanization showed a typical＂U＂ curve shape. Yan＇ an city must continue to improve the process of intensive utilization of urban land, and change the extension and expansion to internal development. Farmland protection must be enforced at the same time.
