摘要
使用河北省塞罕坝机械林场华北落叶松人工林临时标准地资料,探讨了华北落叶松人工林CCF(树冠竞争因子CrownCompetitionFactor的简称)有关特性。该研究有助于全面认识CCF特性以及应用CCF进行林分密度、林分生长收获预估等研究。
A number of characteristics of the CCF of Larix principis-rapprechii plantationare analyzed in this paper by using the data from Saihanba machinery forest farm in Hebeiprovince.And these results are very valuable for detailed knowledge on the CCF characteris-tics and for studing stand density and stand growth prognosis.
