| 摘 要： | 首次采用区域数值预报模式与农业气象模型结合的技术途径, 构成一个气候模式-土壤水分模式-灌溉模式的系统模型。模型的数值天气预报部分采用大气过程与陆面过程耦合的区域气候模式; 农业气象模型采用适用于冬小麦区的土壤水分和灌溉管理预报模型。研究表明, 本模型较农业气象模型中一般用气候平均作为环境背景场的方法其预测能力有显著提高, 并提供覆盖整个小麦生长期的区域土壤水分定量预报和灌溉管理服务, 具有很好的使用和推广前景。

| Abstract: | A climatic soil moisture irrigation system (CSMIS) model has been built firstly by using an integrated technical approach of numerical forecast model with agricultural meteorological model. For the numerical weather forecasting section, a regional climate model is adopted to couple the atmosphere processes with ground processes. A model that was applicable to soil moisture forecasting and irrigation management forecasting in winter wheat fields was adopted as the agricultural meteorological model. The CSMIS has a higher reliability than the models in which climatic average values are used as the background fields. Meanwhile it can make quantitative forecast of regional soil moisture and provide service for irrigation management for the whole growth phase of winter wheat. |
