Abstract:

Based on former work, Xinjiang Tianshan forest ecology station and Xinjiang University, set up a large scale permanent plot in northern Picea schrenkiana var. tianschanica forest covering 8 hm² and then all-around investigation on the plot have been carried out favourably in order to make the long-term observation and research. On the base of its foundation and investigation, the three-dimension visualization analysis and management of the basic information of the plot have been realized based on GIS. This study work is essential and useful for the long time management and maintenance, the refreshment and analysis of basic information and investigation data, the detailed illustration of forest community movements of this large scale permanent plot. It also provides a beneficial case for same work about forest ecology.

Key words: Picea schrenkiana var. tianschanica, large scale permanent plot, GIS, three-dimension visualization
