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。。
According to the stochastic process principle, a new transfer matrix is constructed and a Markov chain soil nutrient evaluation model is established. Through the trend of nearly two decades of three typical nutrient indicators of organic matter, total N and available K in the plain of Chengdu, the feasibility and advantage of applying Markov in the dynamic assessment of soil nutrients were verified, Provided the basis. .
