Yang Wang · Anhui nongye kexue · 2011
Based on the annual precipitation data from 1960 to 1990 in Tai'an area,taking the means and standard deviation of information series as the classification standard of precipitation,the past 30 years were classified into five states: drought year,weak drought year,normal year,weak water logging year and water logging year.The weighted-markov chains model was adopted to establish the annual rainfall prediction model,which could be used as the supplement of the original model.The prediction results are satisfactory.A drought will happen after 34 years.
