洞庭湖镉迁移转化的马尔可夫模型评价

Evaluation on Migration and Conversion of Cd in the Dongting Lake Based on Markov Model

摘要: 讨论了在现时泥沙、水体、鱼类、藻类的含镉状态下洞庭湖的输入输出通量；并以其为例，在简要介绍马尔可夫链数学方法的基础上，建立了湖泊生态系统中镉迁移转化的马尔可夫链数学模型，初步评价了当洞庭湖不断有镉加入、系统到达状态稳定时各种介质中的镉总量及镉的迁移转化趋势。

Abstract: The input and output fluxes of heavy metal cadmium are studied based on the data of cadmium distribution in media of lake sediment, water body, fishes, algae in the Dongting lake, On the basis of the results from this study, a Markov chain model for the p
