摘　　要：营林用火是在人为控制下为达到预期目的而在指定地点进行安全用火的一种技术手段。通过营林用火,可以降低林内可燃物的积累、防止火灾的发生和蔓延、减少病虫害、改善土壤环境和改善林木生长条件。本文通过针阔混交林地堆烧对土壤温度的影响研究,旨在寻找不同燃烧时间对土壤温度垂直分布指标以及土壤温度对土壤养分的影响程度,为营林用火对照土壤环境的改善提供有力证据。The impact of silvicultural use of fire is a technical means for the safe use of fire in a designated place under the control of man.It can reduce the accumulation of fuel in forest,prevent the occurrence and spread of fire,reduce disease and insect pests,improve soil environment and improve forest growth condition.In this paper,through burning test under the mixed coniferous and broad-leaved forests,in order to study the influence degree of different burning time on vertical distribution indicators of soil temperature and soil nutrient,and provide strong evidence for forest fire control to improve the soil environment.
