中文摘要: 将代表站气象要素累加复合成可以反映黑龙江省主要气象灾害的热量指标、旱涝指标等复合因素,并以此为因子预报全省粮食总产量。经大丰收的1990年和大水灾的1991年粮食总产量预报检验,效果较好,两年平均误差为2.62%。
中文关键词: 复合因素，热量指标，旱涝指标，产量预报
Abstract:The meteorological data are accumulated and compounded to "heat index, drought index and water-logging index ", which can represent the calastrophic meteorology in Heilongjiang Province. In this case,the effects of the chilly injury,drought and water-logging damage are considered for the crop yield forecast. The indices can be used to eliminate the average error calculated from the multi-point meteorological data and increase the efficiency of the meteorological data. The test in 1990 (a pumper year)and 1991 (a heavy water-logging year)show 2. 62%. In July and August 1991,an error at a rate of the crop yield was predicted two and three morths ahead respectively, the average accuracy was above 95%.
