| 摘 要： | 采用空间直观景观模型（LANDIS）模拟大兴安岭呼中林区在无采伐和皆伐、二次渐伐和择伐共4种预案下300年内森林可燃物与林火特征的变化。结果表明：采伐降低了森林细可燃物的载量,但不同采伐方式之间没有明显的差别;采伐增加了粗可燃物的载量,皆伐方式增加最明显;采伐导致了林火面积和火烧频率的增加,增加了森林的起火可能性,择伐...

| Abstract: | By using a spatially explicit landscape model(LANDIS),we simulated the long-term(within 300 years) dynamics of forest fire regime under four scenarios of harvesting modes,i.e.,no cutting,clear cutting,gradual cutting and selective cutting,in the Huzhong Forest Region in Da Xing'an Ling Mountains.Results show that forest harvesting could decrease fine fuel loads,but no significant difference occurs among various harvesting modes.Forest harvesting could increase coarse fuel loads,with the largest increase und... |
