杉木人工林全林分模型及货币收获表的研制

Study on Chinese Fir Plantation Stand Model and Monetary Yield Table

利用杉木人工林现场实际造材样木以及木材价格、生产成本、税费等技术经济指标测算单木纯收益,并建立单木货币预估模型。以年龄、地位指数、林分密度为辅助变量,选择Korf理论生长方程构建杉木人工林全林分模型,结合单木货币预估模型按经营类型编制杉木人工林林分货币收获表。应用林分货币收获表,既可预估林分在各种年龄时的木材产量及与材积有关的林分因子,同时还体现了林分货币收获量,在森林资源经营、资产化管理和资产评估中有实际应用价值。

A monetary prediction model for single tree timber was established using pure income,which was calculated by technical and economic indexes including actual sample wood of Chinese fir plantation,timber price,cost of production,and expense of taxation.A Chinese fir plantation stand model was built according to Korf theoretical growth equation using age,site index and stand density as auxiliary variables.These tow models were combined to study Chinese fir plantation stand monetary harvest table through working group.The Chinese fir plantation stand monetary harvest table will predict timber yield at each age,stand monetary yield and stand factor about volume of wood.It has actual application value in forestry resource management,asset management and evaluation.
