| 摘 要： | 定量评估农作物遭受农业气象灾害后的产量损失,尤其是在作物整个生育期过程中遭受多种气象灾害时,定量评估其中单一气象灾害对农作物的影响。是当前农业气象灾害评估中急需解决的问题。在WOFOST作物模型基础上。利用商丘市1980-2005年的气象资料和冬小麦观测资料,对历史上发生的5年晚霜冻灾害进行了模拟分析,选取F_(WSO)和F_(WST)作为评估因子,定义了晚霜冻灾害损失综合指数,实现了灾害损失的定量化评估。与传统方法相比,该评估因子更具有生物学意义,评估结果更加精细。

| Abstract: | To quantitatively evaluate the agrometeorological disasters effect on yield of crops is a problem and key technology to be solved urgently in agriculture production,especially to evaluate the loss of single disaster when there are many agrometrorological disasters in the period of whole growing.WOFOST model describes crop photo- synthesis in detail and is good at simulating crop growth.Based on the meteorological data and winter wheat growing periods data from 1980 to 2005,the loss of frost of 5 years is simulated and analyzed.With the evaluation parame- ters F_(WSO)and F_(WST),the integrated evaluation index for frost loss is defined and the new evaluating method shows to possess stronger biological effects as compared with traditional methods,the results of evaluation are more detailed. |
