摘要
根据随机过程原理,构建了新的转移矩阵,建立了一个马尔柯夫链土壤养分评价模型。并通过成都平原有机质、全N、速效K等三种典型养分指标近二十年的变化趋势,以验证马尔柯夫应用于土壤养分动态评价的可行性及优点,从而为土壤养分动态评价的科学化提供了依据。。
Based on the principle of random process, new transfer matrix and model on Markov chain are built. According to the analysis of the trend of three nutrient in the Chengdu plain during past twenty years, the feasibility and superiority of the model were tested. The basis for scientific dynamic assessment for cultivated land quality was provided.
