摘要： 黑龙江省幅员辽阔,各地气候差异很大,受气候条件制约,作物有明显的地域性分布规律。如何根据地区的气候特点,建立合理的农业结构,充分发挥资源潜力,获得最大的经济收益,是农业生产发展中急待解决的问题。近几年来,晚熟品种和喜温作物大幅度北移,越区种植是作物遭受低温冷害的一个重要因素。因此,作物的合理布局,不但是因地制宜,发挥优势的前提,同时也是避免低温冷害的一项重要措施。作物的合理布局必须首先研究作物生长发育与外界环境因子之间的定量关系,鉴定每个地区气候条件对各种作物的满足程度,其主要标志是产量、稳产程度和经济收益。

Abstract: In this paper,the authors had analyzed the interrelationship between the climatic conditions and the yields of the main crops such as maize,soybean,and wheat in Heilongjiang province;established climate-yield model for yield with solar radiation,dryness index,and mean air temperature in July and August;also analyzed the variation coefficient of climate-yield relationship for various regions.On these bases,the authors determined the major planting regions for maize,soybean,and wheat;and studied the distribution structure of various crops in these major planting regiongs by means of the linear programming method.Consequently,the climatic bases for rational distribution of crops were provided.
