    Based on the remote sensing results of frost monitoring, we established a model to assess the frost damage of mainly crops in Ningxia by using the datum of frost disaster and NOAA(AVHRR) from 1991 to 1996 .Verified results show that, compare to others, the established model is available and objective, and it turned out a good way for assessing the frost damage.
    利用 1991~ 1996年宁夏霜冻灾害资料和同期NOAA(AVHRR)资料和霜冻遥感监测结果 ,构建了宁夏主要作物霜冻灾损评估模式 ,检验结果表明 :所采用模式方法比较客观、实用 ,应用效果好。

    The authors analyze the temporal-spatial regularity of drought, designate criteria of drought with water deficit and evaluate drought conditions in all seasons. The grain yield series in a period of 42 years from 1949 to 1990 is modeled by the method of moving average. According to the percentage of grain yield decrement caused by droughts in the whole province, a model for drought loss assessment is constructed which makes drought loss assessment in Shaanxi province quantitative and provides experiences for quantitative assessment of other disasters.
    分析了陕西干旱发生的时空规律,以缺水率划分干旱标准,评价陕西各季农业干旱状况,并对1949~1990年共42a粮食产量序列进行滑动平均模拟,以粮食减产百分率评估全省干旱灾害等级,得出干旱损失评估模式,使陕西干旱灾害的评估由定性到定量,为其它灾害的定量评估提供了经验。

    By using the percentage of precipitation anomalies and drought index, the standard of drought grade for one station and area are respectively defined, and the maindrought events and their intensity (grade) are assessed in this area for recent 37 years. Finally, the model for assessment of drought-stricken area and area in drought stage isestablished.
    采用降水量距平百分率和干旱指数分别确定了单站及区域于旱等级标准,并对近37a这一地区各年主要干旱事件强度(等级)进行了评定,最后建立了干旱受灾面积和成灾面积评估模式

ased on the updated operational estimates of reference evapotranspiration by PenmanMonteith the relative evapotranspiration in various development stages of winter wheat in North China were calculated. The results show that the proposed drought indexes have agricultural meaning, the analysis and assessments well fit to facts. The agricultural drought impact assessment using integrated model in consideration of winter cold status and water condition in various stages of winter wheat got good results.

利用最新的Penman-Monteith参考蒸散估算方法,计算了华北各地历年小麦各发育阶段的相对蒸散。根据水分亏缺引起的不同减产程度,确定冬小麦各发育阶段干旱指标,并据此分析了小麦干旱程度及发生概率。建立了冬小麦干旱影响综合评估模式。结果表明,干旱指标农业意义明确,分析评估符合实际。利用综合考虑冬季严寒和生育期内各阶段水分状况的模式进行农业干旱影响评估的尝试取得了较好的效果。

Based on the expected yield without meteorological damages, a loss estimation method for agrometeorological disasters was introduced. The determinations of expected yield and its reduction by disasters were also discussed. By analysing the relationship between the yield reduction and several factors including intensity of disasters, influenced area and crop sensitivity to disasters, a constructure based statistical model to estimate the yield reduction by damages was established.

该文提出了以无气象灾害时农作物应当达到的期望产量为基础来评估农业气象灾害损失的问题.介绍了期望产量和因灾减产量的确定方法,依据因灾减产量与相应年份农作物不同生长期所发生的气象灾害的强度、覆盖度以及作物对灾害的敏感度等关系,建立起因灾减产量的结构型统计评估模式
