这种世代结构也受火干扰频率、火干扰强度及两者的综合影响。
Cohort structure is strongly affected by fire frequency, fire severity and their interaction.
研究结果如下：（1）在无采伐预案下，火干扰模式为低频率大面积高强度火烧；
The simulation results were: (1) under simulation scenario without harvest, the fire regime was characterized by low frequency, high fire severity and large fire damaged area;
世代数受火干扰频率、火干扰强度及两者的综合影响，相对来说以火干扰强度的影响更为显著。
The fire frequency, fire intensity and their synthetical regime influenced the number of cohort strongly, while the effect of fire intensity was more significant.
火干扰并未完全地破坏森林，仅仅是导致林分中不同地点上林分组成和红松径阶结构的差异明显。
Fire disturbance only led to a significant difference in stand composition and diameter class structure for the stands at different locations, rather than completely destroying the forest.
本文论述了南方林区森林火灾时间分布集中、发生率高、面积小，并以地表火为主的特征；总结了气象卫星资料的林火信息特征和非林火干扰信息规律；
The forest fire in South China is special for its concentrative time-distribution, the high rate of occurence, the limited fire area and mainly with surface fire.
