摘　　要：【目的】对陕西富平县农用地分等成果的耕地产能进行分析,并探讨计算方法的合理性,为进行耕地产能测算提供新思路。【方法】在农用地分等中的自然质量等级指数与利用等级指数基础上,利用农用地分等的中间成果和数据,结合生态学中的Logistic模型,计算陕西省富平县耕地粮食的自然生产潜力、利用生产潜力和现实生产能力。【结果】富平县耕地自然生产潜力和利用生产潜力分别为298.170×104和179.460×104t,单位面积自然生产潜力和利用生产潜力分别为38.100和22.930t/ha,现实生产能力为79.997×104t,单位面积现实生产能力为10.228t/ha。该县耕地自然生产潜力、利用生产潜力和现实生产能力有从西北向东南递增的趋势。粮食单产在空间上差异明显,单产最高和最低分别是张桥镇和底店乡,分别为12.084和5.634t/ha,差异为6.450t/ha。【结论】富平县耕地的生产能力和生产潜力较大;相比其他方法,利用农用地分等的中间成果和数据来计算耕地生产潜力更加方便;利用生态学中的Logistic模型,可合理模拟现实生产能力。【Objective】Farmland grain potential productivity based on agricultural land classification was assayed using logical calculation method in order to provide new thinking to farmland productivity calculation. 【Method】On the basis of the natural quality grade index and the utilization grade index in agricultural land classification, using the data result of agricultural land classification,the natural potential productivity, utilization potential productivity and actual production capacity of cultivated land of Fuping County of Shaanxi Province were calculated by Logistic model in the ecology. 【Result】The results showed that the natural potential productivity of cultivated land in Fuping County was 298.17×104 t and the utilization potential productivity was 179.46×104 t. The natural potential productivity per unit area was 38.10 t/ha and the utilization potential productivity per unit area was 22.93 t/ha. The actual production capacity was 79.997×104 t, and the actual production capacity per unit area was 10.228 t/ha. The natural potential productivity, utilization potential productivity and actual production capacity showed the increasing trend from Northwest to the Southeast Fuping County. The unit yield of Zhangqiao Town was the maximum （12.084 t/ha）, which was 6.45 t/ha higher than that of Didian Village （5.634 t/ha）, the minimum. 【Conclusion】There is a great production capacity and potential in Fuping County. Calculating farmland grain potential productivity based on agricultural land classification is simpler and more convenient. It is reasonable using the Logistic model of the Ecology to simulate the real production capacity.
