| 摘 要： | 对贵州兴仁梨树坪林场杉木林林火影响下土壤的酶活性进行了研究,结果表明:林火对林地土壤的酶活性会产生极显著的影响.在林火发生的初期,土壤酶活性受到了抑制,之后土壤酶活性得到显著促进,土壤中养分的释放得到加强,但同时也抑制了土壤腐殖物质的积累过程,因此林火发生之后需要及时进行林地清理,并及时补栽造林,以保持林地土壤肥力的可...

| Abstract: | Soil enzyme activity after forest fire was studied in Lishuping forest farm in Xinren County of Guizhou province.Results showed that soil enzyme activity was extremely affected by forest fire.Soil enzyme activity was restrained at the first year but extremely promoted at the 3year,which accelerated the release of soil nutrition but restrained the accumulation of soil humus.It is needed to clean fired forest field and plant new tree immediately for keeping a sustainable soil fertility. |
