摘要
针对农业气象业务的需求,利用东北地区1971～2000年5个代表气象站的气象资料和作物资料,应用玉米生长模拟模型评估东北区域气象条件对玉米生长发育及产量形成的影响。探讨了作为评价标准的平均气候状态下平均模拟生物量的确定方法,提出了从生物量变化、温度和水分条件影响等方面进行实时动态评价和全生育期农业气象条件综合评价的方法,给出了实际评价个例。验证结果表明该方法是可行的。
Aimed at the requirement of agrometeorological services and based on meteorological data and crop data in 1961-2000 in 5 typical meteorological stations, the impact of regional meteorological condition on maize growth and development was assessed by using crop model. The method of calculating average simulated biomass as evaluation standards under average climate condition was studied. The resolution to real-time dynamic evaluating and evaluation summary for agrometeorological conditions during crop growing season was proposed, including change in biomass and effects of temperature and soil moisture. Several case studies were presented. The validation results show that the method is satisfied.
