徐侠 %J 应用生态学报 %D 2008 %I %X By using sequential fumigation-incubation method, this paper determined the soil labile organic carbon (LOC) content under evergreen broadleaf forest, coniferous forest, sub-alpine dwarf forest, and alpine meadow along an altitude gradient in Wuyi Mountain National Nature Reserve in Fujian Province of China, with its relations to soil microbial biomass carbon (MBC), total organic carbon (TOC), total nitrogen (TN), and fine root biomass (FRB) analyzed. The results showed that soil LOC occupied 3.40%-7.46% of soil TOC, and soil MBC occupied 26.87%-80.38% of the LOC. The LOC under different forest stands increased significantly with altitude, and decreased with soil depth. Soil LOC had very significant correlations with soil MBC, TOC, TN and FRB, and its content was obviously higher at higher altitudes than at lower altitudes. %K 常绿阔叶林 %K 海拔梯度 %K 高山草甸 %K 有效碳 %K 连续熏蒸-培养法 %K 武夷山 %K 不同海拔高度 %K 土壤有效 %K 活性有机碳 %K 变化 %K Wuyi %K Mountain %K altitude %K gradient %K organic %K carbon %K soil %K 低海拔 %K 高海拔 %K 相关 %K 土层深度 %K 结果 %K 关系 %K 土壤全氮 %K 根生物量 %K 总有机碳 %K 微生物量碳 %K 有效碳 %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=90BA3D13E7F3BC869AC96FB3DA594E3FE34FBF7B8BC0E591&jid=42FEDDFE54F8BCD9D5FD1926ABDD7722&aid=A6B6A40D742FA3A662527CA313D55D7A&yid=67289AFF6305E306&vid=2A8D03AD8076A2E3&iid=38B194292C032A66&sid=92DA076AF6760FAC&eid=B34BDD6A690A04C0&journal_id=1001-9332&journal_name=应用生态学报&referenced_num=1&reference_num=30
