| 摘 要： | 以山西省方山县和吉县刺槐人工林为研究对象,在依据调查样地、解析木和气象资料估算其耗水量的基础上,初步界定并拟合了人工林水分生产函数。函数表现为以林分年耗水量为自变量,以林分生物量或蓄积量年增量为因变量的幂函数形式。从模型拟合效果看,在刺槐人工林分密度拟合的幂函数、对数函数、二次多项式和线性回归方程等形式的水分生产函数中,以幂函数形式的拟合效果最好;以林分蓄积量年增量和林分年耗水量表述的水分生产函数拟合效果最好。随着林分密度的变化,水分生产函数表现形式无明显的规律性。

| Abstract: | Based on the data collected from plot survey,sample tree analysis and local meteorological observation data,the water production function was modeled by taking the Robinia pseudoacacia plantations in Fangshan County and Ji County of Shanxi Province as research objects to explore the water consumption of the plantations.The quantity of annual water consumption of the stand was the independent variable,while the stand biomass,or the annual increment of the standing volume was the dependent variable in the fun... |
