Abstract: Using the Chinese data base of Foxbase 2.10+ Software,a system of information management has been established for studying the Chinese forests communities,in which the data are inputed with standardizational and numerical method,including vegetation type (subtype);community name;geographic location;altitude;soil type;sample area;community analysis talbe;life form;vertical layer structure and floral element etc. In this system,the data can be processed such as editting,retrivalling, qualificating,reordering,calculating and graphing etc. Especially to operate for plant species diversity analysis,the graph of community vertical structure and the color graphic analysis of life form spectrum and floral element.This system is of simple and fast operation. It is powerful information bases and analysis method for the macroscopic and systematic study of Chinese forest vegetation.
