| 摘 要： | 采用区域气候模式与土壤水分模型相结合的技术,建立黄淮平原农业干旱预警系统。系统的气候模式采用NCAR的区域气候模式(RegCM2),为土壤水分模型提供所需的气象要素场数值预报。土壤水分模型采用适合于黄淮平原冬小麦、夏玉米等作物的土壤水分平衡方程。试运行结果表明,利用区域气候模式和土壤水分模型构建的区域性土壤水分模型,土壤水分预报的平均相对误差在15%以下,可以较好地模拟出土壤水分变化和干旱分布状况,可用于土壤水分预报和干旱监测。

| Abstract: | The system includes a regional climate model and a soil moisture model and is used to study the soil moisture variation and drought-attacked areas.The regional climate model(RegCM2) was adopted to provide the meteorological factor field data for the soil moisture model.A soil moisture balance equation that is applicable for winter wheat and summer maize in the Huanghe-Huaihe plain was adopted as the soil moisture model.The results show that the regional soil moisture model can simulate well the soil moisture variation and drought areas and can improve the prediction precision of soil moisture,with the mean relative error being 15% or less.The system can be used in the forecasting and monitoring of soil moisture. |
