Thisproject,as one ofthesub-project ofthenational science research project called ‘Development ofthedynamic prediction system ofthecrops yield’,based on the dynamic prediction model,is aimed toresearch and develop thedynamic prediction operation system oftheyield ofthecrops inChina anditssome main production area. The business servicesystem was designed and realized on theground of alatest kind of dynamic prediction technology ofthe crops yield,using meteorological conditions topredict theyield ofstaplecropsdynamically,to maintain,to process and toanalyze related data ofthe yield and toacquire thedataofper unit area yield. Therefore,various crops yield could be forecasted by theyieldprediction business operators who have referred tothedataand alsothestatisticanalysis resultsand some othercorrespondent sources,meanwhile p
