本文利用推广的 Richards 生长模型编制了大岗山实验局杉木人工林的可变密度收获表,在这模型中包括地位指数及密度指数。误差分析表明此表适用于该地区的杉木人工林,这种编表方法是一种较好的方法。
In this paper, the variable density harvest table of Cunninghamia lanceolata plantation in Dagangshan Experimental Bureau was established by using the extended Richards growth model. The model includes the position index and density index. Error analysis shows that this table is suitable for the Chinese fir plantation in this region. This method of tabulation is a good method.
