从林分空间结构指标参数出发,提出了以角尺度为主要调整目标的林分空间结构优化方案。结合林木间伐指数,确定间伐木,并进行间伐后林分空间结构的分析,最终确定间伐强度,结果表明:间伐后林分中林木的空间分布格局由团状分布调整为随机分布,林分平均角尺度ω=0.49,混交度得到提高,林木竞争指数和间伐指数均减小,大小比数基本保持不变,林分调整达到预期目标,林分结构得到优化,由此确定的间伐强度为26.2%。
Based on the index of spatial structure index of forest stand, the optimization scheme of spatial structure of stand was put forward with the goal of adjusting scale as the main goal. According to the thinning index of the forest, the thinning wood was determined and the spatial structure of the thinning was analyzed to determine the thinning intensity finally. The results showed that the spatial distribution pattern of the tree after the thinning was adjusted from the clump distribution to the random distribution, The angle scale ω = 0.49, the degree of mixing increased, the forest competition index and thinning index decreased, the size ratio remained unchanged, the stand adjusted to achieve the desired goal, the stand structure was optimized, the thinning intensity was 26.2 %.
