为了解天然次生林保护对土壤活性有机碳库的影响,采用空间替代时间研究方法,对湘中丘陵区不同演替阶段4种林分类型(杉木人工林、马尾松+石栎针阔混交林、南酸枣落叶阔叶林、青冈+石栎常绿阔叶林)土壤活性有机碳及其与土壤养分相关性进行研究。结果表明:1)各土层总有机碳(TOC)、微生物生物量碳(MBC)、水溶性有机碳(DOC)、易氧化有机碳(EOC)含量均表现为:青冈+石栎常绿阔叶林>南酸枣落叶阔叶林>马尾松+石栎针阔混交林>杉木人工林,在0—30cm 土层,马尾松+石栎针阔混交林、南酸枣落叶阔叶林、青冈+石栎常绿阔叶林TOC含量比杉木人工林分别高出13.40%、19.40%和29.91%,MBC含量分别高出15.62%、32.89%和...

Quantification of soil organic carbon as affected by forest succession can facilitate conservation and restoration of the secondary growth forests and increase understanding of the potential for forest ecosystems to sequester carbon. The active pools of soil organic active carbon and its correlations with soil nutrients were investigated for four forest types in central Hunan, China. The four forest types included Cunninghamia lanceolata plantation(PM), Pinus massoniana + Lithocarpus glaber mixed forests(CL), Choerospondias axillaries deciduous broad leaved forests (CA) and Cyclobalanopsis gla...
