摘要/Abstract

摘要： 应用空间直观景观模型(LANDIS)，模拟了小兴安岭友好林业局在有无采伐方案下400年内森林景观的动态变化，并利用统计软件APACK计算代表性树种的分布面积、年龄级和反映物种分布格局的聚集度指数。结果表明：与无采伐相反，采伐下的火干扰模式为高频率小面积低强度火烧；采伐对各种群的分布面积影响不大，但显著改变了种群的年龄结构，主要表现为降低了过熟林的分布面积，而增加了其他年龄级森林的分布面积；采伐降低了各树种的聚集度，导致森林景观一定程度上的破碎化。

Abstract: By using spatially explicit landscape model (LANDIS), the 400 years’ forest landscape changes in Youhao Forestry Bureau in Xiao Xing’an Mountains under forest cutting and non-cutting scenarios were simulated, and the distribution area, age class, and aggregation index of six dominant species were calculated with APACK. The results showed that opposite to noncutting, the fire regime under forest cutting was characterized by high frequency, low fire severity, and small fire damaged area. Cutting had less effect on the distribution of the species, but changed their age structure significantly, being mostly manifested in the decrease of over-matured cohorts and the increase of young, middleaged, quasi-matured, and matured cohorts. Cutting also reduced the aggregation degree of species distribution, resulting in the fragmentation of forest landscape to some extent.
