色季拉山地被可燃物含水率与火险等级划分

摘要

通过对样地的调查和取样,分析了色季拉山的高山松林、冷杉林和云杉林3种不同林型的林下各类可燃物的含水率,利用地被可燃物含水率和载量随不同林型的变化来预测森林火险等级,并对色季拉山的森林火险等级进行了初步划分.结果表明,高山松林属于五级火险等级,冷杉林和云杉林属于一级火险等级,并结合色季拉山的主要火险因素提出了相应的对策.%The moisture content of burnable materials in the ground cover of Pinus densata, Abies fabri and Picea koraiensis in Segrila Mountain were analyzed through investigation and sampling. Then, the forest fire danger level was divied preliminarily according to the moisture content and the load of burnable materials in ground cover. The results showed that Pinus densata belonged to 5 order fire danger, Abies fabric and Picea koraiensis belonged to 1 order fire level in Segrila Mountain. The corresponding countermeasures were given according to fire factors.
