大兴安岭火烧迹地天然次生林土壤微生物生物量及酶活性特征研究OA北大核心CSTPCD
Characteristics of Soil Microbial Biomass and Enzyme Activities in Different Types of Natural Secondary Forest in the Burned Area of Daxingt'an Mountains
探究火烧迹地植被恢复过程中土壤微生物生物量及酶活性的变化规律,为火烧迹地森林恢复途径选择及恢复成效评价提供科学依据.以大兴安岭重度火烧迹地落叶松母树-白桦林(MB)、林下抚育-白桦林(FB)、无干扰白桦林(BB)3种不同类型的白桦林为研究对象,落叶松人工林(LL)为对照,测定0～5、5～10、10～20 cm土壤微生物生物量碳(MBC)、土壤微生物生物量氮(MBN)和脲酶(URE)、酸性磷酸酶(ACP)、蔗糖酶(SUC)、过氧化氢酶(CAT)活性…查看全部>>
Studying the variation patterns of soil microbial biomass and enzyme activity during the vegetation recovery processes of burned areas,providing a scientific basis for reforestation approaches and effectiveness assessment in burned forests.The three dis-tinct types of Larix gmelinii seed tree-Betula platyphylla forests(MB),understory nursery-Betula platyphylla forests(FB),and Betula platyphylla forests(BB)in the severely burned areas in Daxing'an Mountains w…查看全部>>
