| 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%. |
