摘　　要：以延安市为例，对1978～2004年耕地资源面积与城市化水平进行计量和协调性分析，利用SPSS软件构建耕地资源面积与城市化水平的相关回归模型，并借鉴经济与环境协调度模型，计算耕地资源面积与城市化水平的协调度。结果表明，耕地面积号城市化水平存在很强的负相关关系，随着城市化水平提高，耕地面积减少；大部分年份延安的耕地资源与城市化水平协调度呈调和型，耕地资源保持在承载力阈值内，短期内可接受。Cultivated land resources and urbanization development go hand in hand. Take the city of Yan＇ an as an example, the paper has done the measurement analysis and coordination analysis between cultivated land area and urbanization from 1978 to 2004. It structures the relevance regression model of cultivated land area and urbanization level by using the SPSS, and calculates the coordination degree between cultivated land area and urbanization level based on the coordination degree model between economy and environment. The results indicated that there is reverse correlation between cultivated land area and urbanization level. The cultivated land area falls off with urbanization level rising. The coordination degree of cultivated land resources and urbanization level assumes the type of concessions in most ages. Cultivated land resources are kept within bearing the weight of force threshold value, and accepted in a short time.
