中文摘要: 以气象行业标准《区域性高温天气过程等级划分》为基础,依据1981—2018年7月下旬至9月上旬安徽省62个气象站点逐日气象资料,探讨划分出安徽省一季稻高温热害的单站、区域致灾等级指标,将全省一季稻高温热害致灾等级划分为轻、中、重三个等级。采用该指标,对近40年全省一季稻高温热害发生情况进行了试评估。结果表明,该指标可以定量地评估全省一季稻高温热害的致灾程度,历史检验灾害等级符合率达到97%,因此,该指标可应用于安徽省一季稻产量预报和灾害评估业务服务中。
Abstract:Based on daily meteorological data from 62 stations from late July to early September during 1981 to 2018, and the meteorological industry standard Temperature Index of High Temperature Harm for Main Crops, the single-station and regional disaster-causing index of single-season-rice heat injury were divided. According to the regional index, three provincial grades were classified: i.e., light, medium and severe. In addition, the variation of single-season-rice heat injury in Anhui Province in the recent 40 years was analyzed. The results show that, the coincidence rate of historical test of disaster grade reached 97%. It can be used to quantitatively evaluate the effect of heat injury on single-season-rice in the whole province or in a region. Thus, this index can be applied to the operational services of single-season-rice yield prediction and disaster assessment in Anhui Province.
