摘  要:
通过对特金罕山自然保护区可燃物特征类型进行调查分析,结果表明:特金罕山自然保护区各类型林分地表可燃物相对含水率较低,容易发生森林火灾;各林分类型单位面积的地表可燃物载量1 h时滞可燃物>10 h时滞可燃物>100 h时滞可燃物>1 000 h时滞可燃物,1 h时滞可燃物比例约占90%以上,是各森林类型可燃物的主体构成。落叶松人工林单位面积可燃物载量最大,为45.407 t·hm~(-2),已超过发生重特大森林火灾的临界条件(30 t·hm~(-2)),安全隐患极高;其次是山杨、白桦、黑桦混交林及山杨纯林接近临界值,发生森林火灾风险较高。

摘  要:
According to the investigation results of characteristic types of fuels in Tejinhanshan Nature Reserve, the relative moisture content of surface fuels of different forest types in Tejinhanshan Nature Reserve is relatively low, which is prone to forest fire. Characteristics of surface fuels per unit area of each stand type. One hour time-lag fuels> 10 h time-lag fuels>100 h time-lag fuels> 1 000 h time-lag fuels. The proportion of 1 h time-lag fuels is over 90%, and it is the main composition of fuels of each forest type. Among all stand types, larch plantation has the largest load per unit area, and load per unit area is 45.407 t·hm~(-2), which has exceeded the critical condition(30 t·hm~(-2)) for the occurrence of serious and extra-large forest fires, with extremely high security risks. Next, mixed forests of Populus davidiana, Betula platyphylla and Betula dahurica and pure aspen forests are close to the critical value, with relatively high safety in the occurrence of forest fires.
