摘要
采用统计方法，对棉花气象产量与气候因子进行统计分析，得到了各生育时段影响产量的主要降水因子和需水指标，从而根据当年的降水量对棉花产量因旱灾造成的损失程度进行评估，建立区域、省级棉花旱灾损失评估模型。
The statistical method was used to analysis the climatic yield of cotton and the climatic factors. The main precipitation factors and the water requirement index are obtained. According to the year's precipitation, the level of cotton yield damaged by drought can be assessed, then the assessment model of cotton yield damaged by drought was developed for the region and the province as well.
