%X By using two-way indicator species analysis (TWINSPAN) and detrended correspondence analysis (DCA), the quantitative classification and ordination of Cyclobalanopsis glauca community on Karst hills of Guilin were conducted. Based on the results of TWINSPAN classification, 60 quadrats of C. glauca community were classified into 8 association types, with their community characteristics described. Both DCA ordination and TWINSPAN classification exhibited consistent results. DCA ordination preferably reflected the relationships between association types and environmental gradient: The first axis of DCA mainly reflected the gradient change of slope, and the diagonal line of the two-dimensional ordination diagram of DCA indicated the gradient change of aspect. The species composition and distribution of C. glauca community on Karst hills were mainly affected by the slope.
