摘　　要：先对云南古代森林的演化作了概要性的记述。依唯象理论评述"云南森林"的存在,将"森林学"的结构分为四层,由此论述了从一至二,从二至三,以及从三至四的认识过程,最后用马尔科夫过程的"状态与状态转移概率"的数学语言来评述"云南森林"的结构状况。For understanding the evolution of Yunnan forest in ancient time , a brief description was made at the beginning of this paper , and the existence of Yunnan Forest was discussed based on the phenomenological theory . According to this theory , the structure of Forest Science was divided into four levels , and the understanding process from level one to level two , from level two to level three , and from level three to level four was analysis .The struc-ture of Yunnan Forest was evaluated and described in a mathematical language which was State and the Probability of State Transition at the end of this paper .
