The impacts of accelerated erosion on soil nutrient loss and microbial quantity following deforestation in the ziwuling area 子午岭地区林地破坏加速侵蚀对土壤养分流失和微生物的影响研究
Severe fires can often cause changes in successional rates and soil hydrologic functions , degradation of soil physical properties , alter c : n ratios , and result in subsequent nutrient loss through accelerated erosion , leaching or denitrification , and alterations in microbial populations and associated process can occur 高强度火烧往往能引起演替频率的改变,土壤物理性质退化,水文功能发生改变,改变c n比,加剧侵蚀、淋溶和反硝化作用,导致养分流火,微生物数量及其相关过程发生变化。
