摘　　要：根据固定标准地的调查材料，并对林分的密度指数、相对植距指标、生长空间指标进行分析表明：以带密度指数的扩展Richards生长函数为基础模型编制杉木人工林可变密度收获表效果最佳。Investigations on fixed sample plots and analysis on Stand Density index (SDI)、Relative Spacing Index(RSI)and Growing Stand (GS) of 3 density index inside the modle indicated that to construct the variable density yield table for artificial Cunninghamia lanceolata. the generalized Richards growth model which SDI was contained was the bet model of the rest.
