摘　　要：从气候状态向量的观点出发,借助于旋转主分量分析方法,计算各站气候资源向量。在此基础上,将光照、热量、水分等气候环境条件综合为气候资源向量并分别与某种作物的标准生长模式曲线线型建立差异(作物生态适宜度)比较关系,提出一种新的农业气候生产潜力模型。由此得到相对光合生产潜力、相对光热生产潜力和相对气候生产潜力,从而改进了原有的经典计算方法。试验表明,这种改进后的相对生产潜力,具有普遍性和可比较性,适合于对某一种作物在不同地区估算产量的比较。Any regional climate resource is regarded as a kind of climate state vector from the view of climate vector,by means of rotating principal component analysis,the state vector of climate resources is calculated,on the basis of which,the light resource,heat resource,moisture,and other climatic and environmental conditions are integrated as the vector of climate resource.A comparative relationship with a crop growth model of the standard curve is established,and then one new model about the production potential of agro-climatic is put forward.Relative photosynthesis production potential,photo-thermal production potential,and climate production potential have been obtained,all of which prove the limitations of the classic method.The tests show that this improved relative production potential has better universality and comparability,which is suitable for comparing the crop production in different areas.
