不炼山造林技术及应用效果

Application of Non-burning site preparation for afforestation

不炼山造林具有防止水土流失、保持土壤肥力、保护生物多样性、保护林区生态环境、减少CO2及烟尘大量排放、预防和减少森林火灾发生等优点,其生态和社会效益均明显高于炼山造林,利大于弊。为了进一步推广应用不炼山造林技术,从科学采伐、林地清理、整地挖穴、树种选择、良种壮苗、混交造林、控草抚育等技术环节总结了应用此项技术的实践经验,并对其推广应用的成效进行了初步评价。

Application of Non-burning site preparation for afforestation is benefit to prevent loss of water and soil erosion,to maintain soil fertility,to protect biodiversity,to reduce emissions of CO2 and to decrease forest fire.The ecological and social benefit was obviously higher than that in site preparation with burning.To promote further the application of no burning for afforestation,we summarized the practical experience in the technology and evaluated the effectiveness from technical procedures scientific slashes,site preparation,species selection,improved breeds and haleness seedlings,the mixed forest and weed control tending.
