- 摘要:
- 为降低和预防农业气象灾害的影响,根据黑龙江省1980-2015年农业洪涝和干旱数据建立G(1,1)累加预测模型,并对黑龙江省2015年之后出现的严重级别以上洪涝灾害的年份进行预测。结果表明:在1980-2015年,黑龙江省洪涝灾害发生级别高于严重等级的年份符合G(1,1)累加模型x(1)(k+1)=3.786e0.1752k,该模型精度达到了四级,可以利用此模型进行预测。预测得到2015年后严重洪涝灾害出现的年份为2022年;黑龙江省干旱灾害发生级别高于严重等级的年份符合G(1,1)累加模型x(0)(k+1)=15.849e0.0799k,该模型精度达到了二级,利用此模型预测得到严重干旱灾害出现的年份为2020年。
- Abstract:
- In order to reduce and prevent the impact of agrometeorological disasters. Based on agricultural flood and drought data during the 1980-2015 years in Heilongjiang province, a cumulative prediction model of G(1,1) was established, and the year of flood disaster above Heilongjiang level after 2015 was forecasted. The results showed that in the 1980-2015 years, the flood disaster incidence level in Heilongjiang province was higher than that in the severe grade year, which accorded with the G(1,1) accumulation model x(1)(k+1)=3.786e0.1752k.The accuracy of the model reached four level, which could be predicted by this model. The prediction of major flood disasters after 2015 is the year of 2022; Heilongjiang province drought damage level was higher than the severity of the year with G (1,1) model x(0)(k+1)=15.849e0.0799k,the accuracy of the model reached two, using this model to predict the serious drought disasters occurred in 2020 years.
