According to the remote sensing image information of 1998 and 2000 in Fujian Province, the changing state of vegetation species in typical districts of Fuzhou City was drawn, and it was proved that the changing of vegetation species accordes with Markov's course. The dynamic change of vegetation species of Fuzhou City in the following 50 years was predicted by Markov's model. The result indicated that the area proportion of dense woods, mixed needle leaf and broad leaf forest and bush of woods had certain increase, and the area proportion on the economic forest, grass family crops and naked land will have certain reduction. Therefore after the ecological construction for several years, the vegetation productivity of Fuzhou City from the whole aspect, will present the increasing trend and ecological environment towards good condition.
