摘　　要：采用扩展Richards生长函数的方法编制了开化杉木人工林可变密度收获表,并对林分株距指数和密度指数两种密度指标进行了分析,结果认为开化杉木人工林用株距指数这一指标较好。The variable density yield table is established for the Chinese fir plantationin Kaihua county Zhejiang province, which is based on the generalized Richards growth model.The Stand Density Index (SDI) & Spacing Index (SPI) are introduced inside the model and theresults of analyses present that SPI is better than SDI in case of the Chinese fir plantation.
