杨树林光肩星天牛数量分布影响因子分析

Influencing Factors of Quantity Distribution of Anoplophora glabripennis in Poplar Forest

通过研究植被覆盖率、郁闭度、林分位置对光肩星天牛数量分布的影响,结果表明:植被覆盖率、郁闭度及林分位置对光肩星天牛有显著影响,随着覆盖率和郁闭度的提高,光肩星天牛数量越少,并且林缘的数量大于林中的数量。

Through studying the influence of vegetation coverage, canopy density and stand position on quantity dis- tribution of Anoplophora glabripennis, the results showed that vegetation coverage, canopy density and stand posi- tion can influence Anoplophora glabripennis obviously. The quantity of Anoplophora glabripennis decrease with the increase of coverage and canopy density, and the quantity of Anoplophora glabripennis at the edge of forest is bigger than the ones inside the forest.
