【摘要】 通过样地调查和取样分析,分析了林芝县高山松林下各类可燃物的含水率及其资源量。认为林芝县高山松林下可燃物中,死地被物层含水量最低,资源量最大,是高山松林下可燃物的主要组成部分,加之高山松本身含脂量又高,所以高山松林内火险等级高,火灾隐患大。据此,提出了防火建议。更多还原

【Abstract】 With the help of sample plot survey and sampling analysis, the water-containing rate and amount of resources of all kinds of combustibles under alpine pine forest in Nyingchi County are analyzed. It indicates that dead ground covers with the lower water contain and largest resource deposits are the main composition among the combustibles under Pinus densata forest. Moreover, such tree itself contains high pine resin, which leads to high potential risk of forest fire occurrence. Thus, suggestions for fire prevention are also mentioned.更多还原
