| 摘 要： | 以试点中的黑龙江省改培型生物防火林带阻隔系统工程为依托,以可燃物载量为指标,探讨了除草剂对改培型生物防火林带土壤理化性质及防火效果的影响。结果表明:施用除草剂(森草净)后,改培型生物防火林带阻隔体系可燃物载量大幅减少,可有效地阻隔地表火的蔓延,减缓高强度林火的蔓延速度,且3 a后该建带方法未对土壤物理性质产生显著影响。

| Abstract: | A study was performed to discuss the effects of chemical herbicide(Sencaoding) on soil physical and chemical pro-perties and fireproof effect of biological fire belts by transformed cultivation in Heilongjiang Province,using surface fuel loading as an index.Results showed that forest floor fuel loading in the biological fire belts by transformed cultivation significantly decreased after herbicide application,which could effectively separate the spread of ground fire.Moreover,the rate of high-intensity forest fire spread could also slow down.No significant changes in soil physical and chemical properties were observed 3 years after initial herbicide application. |
