摘　　要：通过收集2006-2012年江淮地区水稻生长发育和气象资料,对WOFOST模型进行调参验证,确定了关键发育阶段内所需积温、比叶面积、分配系数和枯萎速率等作物参数,并评价了模型在江淮地区的适应性。结果表明,WOFOST模型可以较好地模拟江淮地区水稻生长发育动态变化过程,开花期、成熟期、叶面积指数(LAI)、叶干物质量、茎干物质量、穗干物质量、地上干物质量和产量观测值与模拟值的RMSE分别为1.73~4.66 d、1.94~4.42 d、0.39~2.51、(0.43~0.86)×10^(3)kg/hm^(2)、(0.86~1.52)×10^(3)kg/hm^(2)、(0.52~1.21)×10^(3)kg/hm^(2)、(1.38~1.96)×10^(3)kg/hm^(2)和(0.45~1.33)×10^(3)kg/hm^(2);NRMSE分别为0.75%~1.96%、0.74%~1.49%、8.74%~43.40%、14.94%~30.55%、18.16%~28.84%、9.44%~22.81%、11.33%~15.89%和5.49%~13.43%,其中合肥水稻发育期,叶、茎、穗和地上部干物质量,镇江水稻LAI和荆州水稻产量模拟效果最优。水稻LAI、叶和茎干物质量随移栽天数增加呈现先上升后下降的变化趋势,而穗和地上部干物质量随移栽天数增加呈现逐渐上升的趋势。This study collected rice growth and meteorological data from 2006 to 2012 in the Jianghuai region and validated the WOFOST model by adjusting plant genetic parameters.The following crop parameters for determining development stages and rice growth,such as accumulated temperature,specific leaf area,distribution coefficient and leaf senescence rate,were calibrated,and the adaptability of the model in the Jianghuai region was evaluated.The results showed that the WOFOST model can effectively simulate the dynamic changes in rice growth and development in the Jianghuai region.The RMSE of the measured and simulated values for flowering period,maturity period,leaf area index(LAI),leaf dry matter weight,stem dry matter weight,panicle dry matter weight,aboveground dry matter weight,and yield were 1.73-4.66 d,1.94-4.42 d,0.39-2.51,(0.43-0.86)×10^(3)kg/ha,(0.86-1.52)×10^(3)kg/ha,(0.52-1.21)×10^(3)kg/ha,(1.38-1.96)×10^(3)kg/ha,and(0.45-1.33)×10^(3)kg/ha,respectively and the NRMSE were 0.75%-1.96%,0.74%-1.49%,8.74%-43.40%,14.94%-30.55%,18.16%-28.84%,9.44%-22.81%,11.33%-15.89%,and 5.49%-13.43%,respectively.Among different study stations,rice development stage,dry matter weight of leaves,stems,panicles,and aboveground in Hefei,LAI in Zhenjiang,and yield in Jingzhou presented the most accurate simulation results.The LAI,leaf and stem dry matter weight of rice first increased and then decreased with the increase of transplanting days,while the dry matter weight of panicles and aboveground parts showed a gradually increasing trend with the increase of transplanting days.
