摘要:

为探讨解决马尾松纯林火灾风险大的问题,采用强度间伐马尾松套种细柄阿丁枫、木荷、闽楠的林相改造试验,对改造20年后的林分进行生物量、林下植被、冠层结构、小气候特征、抗火性能特征值等进行测定。结果表明:易燃可燃物,马尾松纯林为37.91±4.55 t/hm 2,而马尾松细柄阿丁枫、马尾松木荷、马尾松闽楠混交林分别为23.71±2.36,22.54±1.85,21.58±2.03 t/hm 2;林下植被,马尾松纯林以芒萁和杂竹类为主,而混交林以一、二年生的荫性草本为主;在空间结构上,马尾松纯林由马尾松林冠层、林下植被层和凋落物层组成,而混交林由马尾松林冠层、阔叶树林冠层、林下植被层和凋落物层组成;马尾松叶子的着火温度比阔叶树低,油脂含量比阔叶树高;马尾松林分的林内温度比混交林高,林内湿度比混交林低。马尾松林分套种阔叶树后,防火风险显著降低,防火效能从高到低分别为马尾松细柄阿丁枫、马尾松木荷、马尾松闽楠、马尾松纯林。

Abstract:

In order to explore the problem of solving the fire risk of Pinus massoniana,interplanting Altingia gracilipes,Schima superba and Phoebe bournei under the canopy of P.massoniana was tested.After 20 years of stand improvement,the biomass,undergrowth vegetation analysis,canopy structure,microclimate and fire resistance were analyzed,results show that combustible was 37.91±4.55 t/hm 2 in P.massoniana,combustible were found in the mixed forests of P.massoniana with A.gracilipes,S.superba,P.bournei,which were 23.71±2.36 t/hm 2、22.54±1.85 t/hm 2、21.58±2.03 t/hm 2.The undergrowth vegetation of P.massoniana were Dicranopteris dichotoma and miscellaneous bamboo,while the undergrowth vegetation of mixed forest were dominated by one or two-year-old shady herbs.The spatial structure of P.massoniana were composed of forest canopy,undergrowth vegetation and litter layer,while that of mixed forest were composed of forest canopy,broad-leaved forest canopy,undergrowth vegetation layer and litter layer.The ignition temperature of P.massoniana leaves was lower than that of broad-leaved trees,and the oil content was higher than that of broad-leaved trees.The temperature of P.massoniana were higher than those of mixed forest,and the humidity of P.massoniana were higher than those of mixed forest.When broad-leaved trees were intercropped in P.massoniana,the fire-fighting efficiency was significantly improved.The fire-fighting efficiency ranged from high to low as follows:P.massoniana and A.gracilipesP.massoniana and S.superbaP.massoniana and P.bourneiP.massoniana.

Key words: Pinus massoniana, Altingla gracilipes, Schima superba, Phoebe bournei, stand after interplanting, fire prevention efficiency
