Abstract: 【Objective】Explore the spatial structure characteristics of a Cunninghamia lanceolate coppice forest plot in Longquan City, Zhejiang Province, and to provide a theoretical basis for optimizing spatial structure of the study plot.【Method】We conducted field investigations in the plot and used bivariate distribution of structural parameters to examine the spatial structure of C. lanceolate and Schima superbain this plot.【Result】The results showed that: ① The most tree individuals in this plot were randomly distributed and belonged to weak or moderate mingling degrees, trees with different neighbourhood comparison were approximately equal in number. Only a few trees in medium-sized state were randomly distributed. Moreover, the number of relatived disadvantaged trees was more than that of the advantaged trees.② Almost all the C. lanceolata trees were in moderate mingling degree, which indicated a very few individuals of the C. lanceolata were mixed with other species in the plot. On the same mingling degree, the trees in different dominance status have significant difference in number. ③ S. superba was randomly distributed in the plot, and the most individuals were in the medium or disadvantaged status.【Conclusion】These features revealed that the most tree individuals were lowly mixed in the study plot, to improve C. lanceolatae coppice forest toward random distribution and ideal structure, the stand density and the native tree species need to be adjusted through thinning and replanting.
