浙南山区生物防火阻隔林带营造技术试验

通过生物防火林带结构模式的研究,对泰顺县火灾现场进行实地调查后,研究和分析常绿阔叶林中不同植物种类的抗火性、耐火性和燃烧性,筛选出用于生物防火林带建设的植物种类,并进行生物防火林带造林试验、结构与配置、造林规格及位置的研究.试验表明,由乔木-亚乔木-灌木构成复层结构,配置境界、主、副防火林带,结合山脊、山谷位置的防火林带,能达到理想的生物防火效果;对木荷、杨梅、茶叶等17个树种进行枝叶含水量和抗燃时间的测定的结果表明,杨梅、木荷、女贞、山杜英、甜槠、广玉兰、红花油茶、油茶、茶叶等树种可选为生物防火林带造林,其防火和阻燃性能比较理想.开展生物防火林带造林,经检查造林保存率与成活率均在85%以上,幼树生长良好

Technological Tests of Biological Fireproofing Forest Belt in Mountainous Areas of South Zhejiang

By researching into the model of bio-fire forest structure as well as investigating the fire scene in Taishun County,research and analyze the fire-resistance,fire resistance and flammability of different plant species from evergreen broad-leaved forest,sort out the plant species screened for biological fire belt,and research into biological fire belt afforestation experiment,the structure & configuration,specifications and location of afforestation.Tests showed that the stratified structure of trees-Yaqiao wood-shrubs,configure the realm,Lord,the Deputy Fire Belt,combined with the ridge and valley location of the fire belt,can achieve the desired biological fire;the result of measuring the foliage water content on Schima bayberry,tea and other 17 tree species and the anti-burning time indicates that many plant species are optional for the biological fire belt afforestation such as bayberry,Schima,privet,Elaeocarpus sylvestris,eyrei,magnolia grandiflora,safflower oil,tea,camellia,tea etc.Besides,its fire and flame retardant properties are ideal.By carrying out and checking the biological fire forest reforestation,preservation rate and survival rate reach to more than 85%,and the young trees can grow well.
