摘要
探讨了粮食单产风险的涵义,给出了测度粮食单产风险的方法,并用马尔科夫预测法建立了福建粮食单产风险的预警系统,得出了未来年份福建粮食单产风险的警度。
In this paper, the connotations of the risk of grain yield per hectare are explored and a new method is proposed to measure the risk of grain yield per hectare in Fujian province. Meanwhile, an early warning system of the risk of grain yield is built up and the risk degrees are forecasted by Markov forecasting method.
