| 摘 要： | 三江地区位于我国东北端,包括三江平原、兴凯湖平原及其毗邻地带,面积约10万余平方公里,是我国重要的商品粮基地和垦区之一。本文分析计算了三江地区的光、热资源,着重探讨了光温潜力。考虑温度对不同作物生产力的影响,我们提出一种计算C_4作物、C_2喜凉作物和C_3喜温作物的温度影响参数的经验公式。据此,估算了三江地区春小麦、大豆、玉米和水稻等四种主要农作物的生产潜力;并与实际高产值作了比较。最后,就三江地区光、热资源的开发利用问题进行了讨论。

| Abstract: | Sanjiang region is in Heilongjiang Province in the northeastern part of china, its area is about 106800 km2. It is now an important regian of grains and one of the major reclamation areas in northeastern China.In this paper, the solar light and thermal resource in San jiang region are analyzed with the emphasis on the photosynthesis-temperature productivity. By considering the influence of temperature on the potential productivity of various crops, we suggested an empirical formula for estimating the temperature-influence parameters of C4-crops, C3-cool season crops and C3-hot season crops.On this basis, the potential productivity of the lour major crops (spring wheat, soybean, maize and rice) are estimated in Sanjiang region.Finally, sorle questions related to the exploitation and utilization of the solar light and thermal resource in Sanjiang region are discussed. |
