摘要
介绍了农作物产量灾害损失评估业务化方法。该方法采用新的求解趋势产量的方法获得农作物产量受灾损失率,用区域内多个代表站的资料进行全区灾害损失的估算,扩大了样本容量。在单灾种评估中考虑作物敏感性和气候脆弱性,在综合灾损评估中增加灾害的重要度权重因素。经验证,估算精度可满足业务应用需求,在业务服务中可行实用。
An operational method of crop yield disaster losses evaluation is introduced. In this method, crop yield loss rate are obtained by a novel method of division crop trend yield. Disaster losses of the area are assessed based on the data of some representing stations, thus samples numbers are enlarged. Crop sensitivity and climate vulnerability are considered in single disaster assessment model. The weights of various disasters are considered yet in the multifactor assessment model. This method is convenient and practical in operation application. Its estimate precision can meet accuracy requirements of operation application.
