摘要: 根据样地调查、解析木和气象资料,拟合了晋西刺槐(Robinia pseudoacacia Linn.)人工林基于耗水量的幂函数密度调控模型。其中,以单株材积连年生长量和单株胸径连年生长量表示的模型拟合效果较好。研究表明,干旱、半干旱区有必要在传统密度控制图基础上,以水分资源环境容量为基点,以不同林龄水分消耗与降水资源平衡原则,制定基于降水量的不同林龄林分密度控制图。

Abstract: According to the sample plot investigation and analysis of wood and meteorological data, the power function of water consumption-based density regulation model for western Shanxi black locust plantations is formulated in this paper. The model fitting with annual increment of individual tree-volume and annual single plant increment of DBH showed a better effect. The results show that different forest stand density control chart should be formulated based on the precipitation for the arid and semi arid areas on the basis of the traditional control chart, with water resources and environmental capacity as the starting point and water consumption of different forest of different ages and precipitation balance as the principle.

Key words: Robinia pseudoacacia, plantation, density control models, Western Shanxi Province
