在阐述作物光合、光温、气候、土地生产力、生产潜力、产值潜力的概念及计算公式的基础上．提出了用生产潜力和潜力指数定量测度区域农业生产潜力的方法．对评价一个地区的生产潜力、指导农业生产发展具有重要意义。在对内江市的实例研究中．得出光能利用率和水资源利用率低是造成该区作物产量不高的主要原因；该区各种作物中水稻生产力、生产潜力最大，耕作制度以水旱轮作为最佳。
Based on the concept and formula of crop photosynthesis, light temperature, climate, land productivity, production potential and output potential, A method of quantitatively measuring the potential of agricultural production in the region by using the production potential and potential index is proposed. It is of great significance to evaluate the productive potential of a region and guide the development of agricultural production. In Neijiang City case study. It is concluded that the utilization rate of light energy and the low utilization rate of water resources are the main reasons for the low yield of crops in this area. The productivity and production potential of rice in various crops in this area are the highest, and the dry farming system is the best.
