选择多大的采伐强度对森林的经营起着关键性的作用。
The choice of felling intensity plays the key role in the forest management.
结果表明：采伐强度与林分年平均蓄积生长量和更新株数间呈抛物线关系。
Results showed that the relation equations was parabola equation between cutting intensities and annual average increment and annual average number of regeneration individuals of stands.
影响油锯择伐作业中保留木损伤率的因素很多，经过分析可知采伐强度、林分密度和采伐木单株材积是影响保留木损伤率的主要因素。
Selective cutting intensity, stand density and felling tree volume per stem were considered as the major influencing factors by analyzing related researches at home and abroad.
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;
