摘　　要：根据浙江省２１个县（市）２９０块样地的优势解析木和平均解析木数据，以修正的Ｒｉｃｈａｒｄｓ函数为数学模型，用Ｍａｒｑｕａｒｄｔ迭代法求出优势高、平均高和平均胸径生长曲线的拟合方程，从而编制出多形地位指数表和多形林分生长过程表。拟合方程中引入一系列形状系数（Ｂ１、Ｂ２等），因此对该省不同地区、不同生长条件下具有不同线形的马尾松生长曲线，有较好拟合效果。无论在全省或Ⅰ、Ⅱ、Ⅲ类产区（每区含样地９０～１００块），模拟精度都很高，其中复相关系数达０．９９以上，剩余标准差为０．１～０．３。另据Ｒｅｉｎｅｋｅ（１９９３）关于完满立木度同龄纯林胸径与单位面积株数关系的理论，用函数Ｎ＝Ｃ０＋Ｃ１／（Ｃ２＋Ｄ）进行林分胸径一立木株数相关关系模拟，最后编制出浙江省８～１６指数级的马尾松人工林生长过程表。According to the data of 290 oriented plots and 580 analysis trees(both aver-age and dominated ones)from plantation of Pinus massoniana in 21 counties of ZhejiangProvince,and the revised Richards function is selected as a mathematical model.The domina-tion and average height and DBH of the growing process have been simulated by the imitatedequations which calculated through Marquardt repeat replacement method The Multi-formed site index and Growth Processing Tables have been established.A series of form co-efficients are introduced into the equations(such as B1, B2 etc.).So they have fine simulatingeffect to the different formed growth curves of the species in different region of the province.The statistical tests shows:the complex relative coefficients are all higher than 0.99 and theremainder S. D. are 0.1～0.3 in the the province or its three productive regions(Ⅰ2、Ⅱ andmdegree regions,each contained 90～100 plots);In addition the relationship between thedensity per unit area of standard stand(density of the crop is 1.0)and DBH is simulated ac-cording to the theory of Reineke(1933)on full density of stocking and the function of N=C0+C1/(C2+D)has been used.At last,the growing process table of the species in Zhejiang isestablished.
