摘要
文章选择17a生的杉木中龄林样地,进行每木检尺与定位,运用角尺度分析杉木空间分布格局时空变化,研究结果表明,样地内杉木的平均角尺度为0.463,呈均匀分布。对不同径阶的杉木角尺度的分布的研究也表明,杉木基本为均匀分布,但随着胸径变大有转变为随机分布的趋势。
The plot of Cunninghamia lanceolata at the age of 17a was selected and investigated in the half-mature forest, based on the method of tally stem analysis and Coordinate Positioning, angle scale was used to analyze the temporal and spatial variations of the Cunninghamia lanceolata spatial distribution pattern, the results showed that the uniform angle index was 0.463 and even distribution, uniform angle index of different diameter were evenly distributed too, however, with the change in diameter becomes great tendency to random distribution.
