应用ARIDCROP模型对黄淮海地区冬小麦气候生产力进行了数值模拟研究,给出了该地区冬小麦气候生产力Yq分布图,继而研究了水分保持最适状况时的光温生产力Yw分布状况,在此基础上给出了水分增产力Q(Q=(Yw-Yq)/Yq)分布图。研究表明,黄淮海地区冬小麦气候生产力变幅在3750~9750kg/hm2之间,总的趋势北低南高,黑龙港地区出现了一个3750kg/hm2的低值区。水分是黄淮海北部地区冬小麦气候生产力的一个重要限制因子,当水分完全适宜时,南部淮河流域冬小麦气候生产力仅可提高5%~10%,而黄淮海北部地区气候生产力则可提高75%~100%。用黄淮海地区冬小麦高产记录与生产力模拟值进行了对比分析,表明用ARIDCROP模型对该地区冬小麦气候生产力进行研究是可行的,该研究为引黄灌溉提供了一定的理论依据。
Using ARIDCROP model to simulate the winter wheat climate productivity in Huang-Huai-Hai region, the Yq distribution of winter wheat productivity in the region was given, and then the distribution of light-temperature productivity Yw in the optimum condition of moisture was studied. On this basis, Out of the water yield Q (Q = (Yw-Yq) / Yq) distribution. The results show that the climate productivity of winter wheat in Huang-Huai-Hai region fluctuates between 3750-9750kg / hm2. The general trend is north and south high. There is a low value area of 3750kg / hm2 in Heilongjiang. Moisture is an important limiting factor for winter wheat climate productivity in the north of the Huang-Huai-Hai region. When the water is suitable, the climate productivity in the southern Huaihe River can only increase by 5% ~ 10%, while the climate productivity in the north of Huang-Huai-Hai can increase by 75% ~ 100 %. Comparison of high-yield winter wheat records and simulated productivity values in Huang-Huai-Hai region shows that it is feasible to use ARIDCROP model to study the climatic productivity of winter wheat in this area. This study provides a theoretical basis for irrigating.
