| 摘 要： | 本文提出邻体干扰的改进模型：并提出基株与邻体的确定原则和计测方法。以不同密度的华北落叶松人工林为测试对象，分析干扰指数与基株胸径、材积连年生长量、树冠发育、主干高径比等几个主要生长和形质指标的关系，探讨干扰指数与基株对生境资源利用效率的相关变化规律。结果表明，该指数是计测林木生长状况及在林分中所处地位的数量指标。

| Abstract: | An improved neighbouring tree disturbing model A. Li is described in the paper, meanwhile criterion and measuring method for determining basic tree and neighbouring trees are suggested. Data of different densities of Larix principis-rupprechtii plantations were used to reveal the relationships between disturbing index and the dbh, volume current annual increment, crown development and ratio of height to dbh of the basic tree and to inquire into the variation pattern of the disturbing index with the habit utilization efficiency of the basic tree. The results showed that the disturbing index was a quantitative index for evaluating growth situation of trees and position of trees in the forest. |
