| 摘 要： | 以我国南方速生丰产林——杉木纯林为研究对象，采用改进过的Hegyi的简单竞争指数模型对杉木纯林间的竞争强度进行定量分析，并建立单木生长模型，再通过径阶模型将其应用于全林分，将单木生长模型研究扩展到全林分生长模型研究。同时，通过可视化模拟技术，为更加逼真的恢复和重建林分空间结构提供理论依据。

| Abstract: | 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. |
