摘要: 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/hm之间,总的趋势北低南高,黑龙港地区出现了一个3750kg/hm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。

Abstract: he ARID CROP model is used to study the numerical simulation of the climatic productivity of winter wheat in the Huanghuaihai region .The distribution map of the climatic productivity (Yq) is given first. Then the distribution condition of the productivity of photo temperature (Yw) is studied at the time when the moisture condition is most suitable.On the basis of these studies, the distribution map of the increasing production force of moisture Q(Q=(Yw-Yq)/Yq) is given. The results show that the climatic productivity of winter wheat in the Huanghuaihai region changes from 3 750~9 750 kg/ha , the general tendency is that the value is lower in the north but higher in the south, and there is a low value of about 3 750 kg/ha in the Heilonggang Area. Mois ture is a main factor which limits the climatic productivity of winter wheat in the northern part of the Huanghuaihai region.When moisture is suitable for winter wheat growth, the climatic productivity can only increase about 5%~10% in the southern part of the Huaihe River basin, whereas in the northern part of the Huanghuaihai region it can increase about 75%~100%. The high production records of winter wheat in the Huanghuaihai region are used to compare with the simulate value of productivity . The results show that it is feasible to simulate the climatic productivity of winter wheat by using the ARID CROP model in the Huanghuaihai region. This study will provide a theoretical basis for conducting water from the Huanghe River for irrigation to a certain extent.
