| 摘 要： | 本文根据对一元回归积分原理进一步理解的基础上，结合大量的实践与试算，提出了多元回归积分的概念和计算方法。利用上方法计算了汉中地区农科所的水稻产量及光温资料，所得光温回归积分函数曲线与汉中盆地水稻生产实际相吻合。文章最后在综合国内外生产潜力方法的同时，给出了利用光温回归积分函数曲线与各时段的偏差计算光温生产潜力的公式。

| Abstract: | Based on further comprehension of single regressive integration and a large number of calculations, the concept and computation method of multiple regressive integration were proposed.Regressive integration curve based on thermal and solar light data and rice yield from Han-Zhong Institute Agricultural Science is coincident with the actual rice production of Hanzhong basin. Finally, we present the formula for potential productivity analysis using the photo-thermal regressive integration curve and its difference between each interval while synthesizing various computing methods of the potential productivity. |

| Keywords: | regressive integration light and thermal potential productivity orthogonal functions |
