在位于亚热带丘陵区的长沙县大山冲林场选取地域毗邻、环境条件(立地、土壤、气候)基本一致的杉木人工林(CL)和3种次生林:马尾松-柯(又名石栎)针阔混交林(PM-LG)、南酸枣落叶阔叶林(CA)、柯-青冈常绿阔叶林(LG-CG),每种林地随机设置5个20 m×20 m的样地,分别采集表层(0—15 cm)和亚表层(15—30 cm)土壤样品,测定土壤微生物生物量碳(B_C )、氮(B_N)、磷(B_P)和蔗糖酶(INV)、脲酶(URE)、酸性磷酸酶(ACP)、过氧化氢酶(CAT)活性,分析4种林地土壤微生物生物量和酶活性及其与土壤化学性质的关系。结果表明:表层和亚表层土壤B_C、B_N、B_P和ACP活性依次为:CA >LG-CG >PM-LG >CL,INV和URE活性依次为:LG-...

We selected four forest types, comprising of Cunninghamia lanceolata plantation (CL), Pinus massoniana- Lithocarpus glaber coniferous-broad leaved mixed forest (PM-LG), Choerospondias axillaris deciduous broad leaved forest (CA) and Lithocarpus glaber-Cyclobalanopsis glauca evergreen broadleaved forest (LG-CG) in Changsha County, Hunan Province, in a mid-subtropical hilly region of China. Five permanent plots (20 m×20 m) were randomly established in each forest type. Soil samples (0-30 cm) were collected and divided into two layers (0-15 and 1...
