摘要
在前期试验所建立的落叶松人工林林分株树密度、林分断面积和林分蓄积生长预估模型的基础上,根据净现值法和内部收益法计算得出落叶松人工林的经济成熟龄,并与林分数量成熟龄、工艺成熟龄进行了对比分析。研究结果对本地区落叶松集约化经营采伐年龄的确定具有一定的指导借鉴意义。
Based on the preliminary tests that established a sub tree density and stand basal area,and stand volume growth prediction modelin Larch Plantation,this paper calculated the economic mature ageaccording to the net present value method and the internal rate of return,and comparative analysis with the stand number of mature age and mature age. The results of the study in the region set which has a certain guiding significance to determine the operation of intensive harvesting age.
