摘  要:
以浙江临安为研究对象 ,以 1 983、1 989、1 994年森林资源调查的 3期森林分布图为主要信息源 ,以 ARC/INFO作为空间信息处理工具 ,采用马尔柯夫过程模型进行森林景观动态的计算机仿真。结果表明 :森林景观类型的比例与林地利用的经济效益成正比 ,并受市场行情波动的影响较大 ;松林和阔叶林等天然林景观比例减小 ,竹林和经济林等人工林景观比例增大。

摘  要:
With the help of GIS tool of ARC/INFO and based on the information from three successive period forest distribution maps in 1983,1989 and 1994, simulation model of Markov was used to analyse dynamic of forest landscape in Linan,Zhejiang province.Results showed that the area proportion of each forest landscape type was strongly influenced by comparative earnings of land exploitation and would change with fluctuation of market price. The area of natural forest landscapes,such as hard wood forest and pine forest, decreased gradually while the area proportion of artificial forest landscapes, such as bamboo groves and economic forest, increased steadily.
