黑茶山自然保护区森林可燃物类型的划分

摘要

通过对山西省黑茶山国家级自然保护区森林可燃物类型的划分，为保护区制定防火计划提供数据参考，并逐步探索华北地区森林可燃物类型的划分方法。在黑茶山自然保护区内进行样地设置、调查和可燃物取样等工作，通过对可燃物的负荷量、含水率指标的测定，林火蔓延率、火焰高度和空间分布连续性测定及林分蓄积量的计算等对黑茶山自然保护区森林可燃物类型进行划分，结果显示：黑茶山国家级自然保护区主要划分为极难燃、低等易燃、易燃和极易燃等4个易燃等级和华北落叶松林、阴坡针阔混交林、阴坡油松林、青毛杨林、白桦林、阳坡针阔混交林、阳坡油松林和落叶灌木林等8种可燃物类型。%In this work ,the forest fuel type of Heicha Mountain national nature reserve areas in Shanxi province was divided ,in an attempt to provide reference data for making fire prevention plans in reserve areas ,and gradually ex-plore the forest fuel type classification method of the North China .Setting and investigating the sample areas ,and sampling fuel materials were conducted in Heicha Mountain nature reserves areas .By measuring the fuel load ,mois-ture index and forest fire rate of spread ,flame height ,continuous and spatial distribution ,and forest stand volume , the calculated results showed the forest fuel types in this area were mainly divided into eight kinds of fuel types ,in-cluding Larix principis- rupprechtii ,shady-facing slope mixed coniferous and broad forest ,shady-facing slope Pi-nus tabuliformis forest ,Populus shanxiensis forest ,Betula platyphylla forest ,south-facing slope mixed coniferous and broad forest ,south-facing slope Pinus tabuliformis forest ,fall-leaved shrub forest ,and four flammability rat-ing s .
