摘要
对植物空间格局提出独占圆的新概念,证明与独占圆有关的3个引理,从而提出均匀度指标,进一步推导均匀度的理论分布及格局类型检验方法。用高精度仪器测量林木空间位置分布,应用新的均匀度指标进行格局类型检验。新的均匀度指标计算方便,有更好的理论依据和直观性,特别适用于森林择伐对空间格局的控制。
The new concept monopolized circle was put forward to plant pattern, three theorems relating with monopolized circle was proved and then uniform index was put forward, the theoretical distribution and testing method of pattern type was derived. The forest tree＇s positions were measured with high precision instruments and the patterns were tested with new uniform index. The new uniform index is easy to calculate, intuitionistic to understand and rational, which is actually used to control the forest tree＇s pattern in forest thinning.
