The fast-growing and high-yielding Cunninghamia lanceolata pure stands in south China were used to analyze quantitatively the competition intensity among C.lanceolata stands by adopting improved Hegyi's simple competition index model, and the individual tree growth model was built. Then the Hegyi's simple competition index model was used for whole stand by diameter class model, in order to broaden individual tree growth model to whole stand growth model. Meanwhile, the visual simulation technique could provide a theoretical basis for restoring and rebuilding the stand spatial structure more realistically.
