| 摘 要： | 作物布局是农业生产的一个重要环节,直接关系到农业生态系统资源输入(物质条件、科学技术、气候资源和生物资源等)的利用和转化效率的高低。因为系统输入的资源是非定常的,尤其是天气气候条件年际之间是不同的,本文在年型预测的基础上,确定在不同天气气候条件下的作物合理布局。

| Abstract: | Crop layout is an important link in agricultural production, and it has direct influence on the efficiency of the utilization and transformation of agroecosystem resources, which include the material conditions, science and technology, climatic and biological resources, etc. This is due to the variability of agroecosystem resources, especially the year to year difference of the weather and climate factors. This paper aims at determining the optimum crop layout under various weather and climatic conditions on the basis of the year pattern forecast. |

| Keywords: | crop layout agroecosystem resources year pattern. |
