不同密度大叶相思林的竞争效应
Density-Competitive Effects ofAcacia auriculiformis Stands
摘要
Abstract
The competition index was studied in Acacia auriculiformis stands with different densities to provide theory basis for rational utilization and management of the stands. The results showed that competition index of all the organs in theA. auriculiformisstands tended to decrease with decreasing density. At the same density level, competition index of above-ground was greater than that of below-ground. Significant correlation was found among below-ground, above-ground, and total competition. Coefficients of path analysis, in three densities levels, indicated that the direct influence intensity of above-ground competition on total competition was greater than below-ground competition.关键词
