| 英文摘要 | The drought index is an important indicator of regional drought condition. The standard deviation of information series was applied to set up the classification of drought index. Since the drought index is dependent random variables, Weighted Markov chain was introduced to predict the future drought index, weighted by the standardized self-coefficients. Drought index of Nanjing City from the year 1959 to 2004 were a specific application with this method and satisfactory results were obtained. Therefore the weighted Markov method provides a new way to predict future drought condition. |
