The Models for Growth Process of Spruce-fir Forest

摘要：

　　Pass in the Wang Qing in Jilin province Jingouling forestry station to establish temporary study plot,carried on stem analysis,analysis spruce-fir wildwood growth process,discovered spruce-fir DBH for current annual increment at hit maximum for 50 years and 100 years,respectively is 1.14cm and 1.07cm.Height of tree current annual increment at 30 years and 75 years maximum,respectively is 0.49m and 0.66m.In spruce-fir volume of wood growth process,volume of wood current annual increment is higher than average increment.The Quadratic can the good fitting spruce-fir height curve,secondly is Logarithmic,their correlation coefficient respectively is 0.985,0.982 and 0.979,0.935.
