摘　　要：研究粮食产量与耕地产能间的关系以及区域差异,对于挖掘区域增产潜力,提高耕地资源利用效率,实现区域均衡增产,保障粮食安全战略具有重要意义。该文在农业生态区划法估算土地生产潜力基础上,提出基于耕地质量新内涵的耕地质量修正的耕地产能核算方法。通过探讨耕地综合产能的概念体系,构建了反映粮食产量与耕地产能关系的耕地综合量能指数模型,模型由耕地综合量能指数、耕地质量产能指数和耕地数量产能指数构成。并以曲周县为例,对该模型进行了实证研究,曲周县耕地综合量能指数为0.16,耕地质量产能指数为0.31,耕地数量产能指数为0.99,耕地总体产出效率不高,粮食增产的潜力较大,耕地粮食生产平均开发程度也不高,但数量增加潜力较小。Study on the relationships between grain production and cultivated land productivity and its regional difference is of great significance for food security. Besides, it is also important for finding regional potential yields of grain, improving the utilization efficiency of cultivated land resources and achieving the regional increase of grain yield. In this paper, on the basis of agro-ecological zoning （AEZ） model, a new method was proposed to calculate the cultivated land productivity under cultivated land quality modification. Furthermore, the modification of cultivated land quality was based on a new concept that the quality of cultivated land was not only affected by natural factors but also by artificial factors such as irrigation canals, greenhouse, nursery factory, mechanical facilities and its supporting service station. By discussing the conceptual system of cultivated land integrated productivity which took the potential quantity of cultivated land and the quality index of cultivated land into the consideration, we proposed that comprehensive productivity of cultivated land was the maximum sustainable production capacity for food under the certain economic and technological conditions, and it was strongly affected by the quality and quantity of cultivated land. Additionally, according to the concept, we built a model which can reveal the relationship between grain production and cultivated land productivity. This model was made up of comprehensive yield and productivity index of cultivated land （CLYPCI）, cultivated land quality productivity index （CLQLPI）, and cultivated land quantity productivity index （CLQNPI）. The CLYPCI was used to measure the efficiency of cultivated land grain production and to reveal the relationship between actual output of grain and cultivated land productivity in a particular area. The CLQLPI was used to describe the average output efficiency of a regional cultivated land. The CLQNPI was used to measure the degree of exploitation and utilization of cultivated
